WARNING

SUPPLEMENTAL RESTRAINT SYSTEM

A Supplemental Restraint System (SRS) is standard factory-installed safety equipment on this vehicle. Available supplemental occupant restraints for this vehicle include both active and passive types. Active restraints are those which require the vehicle occupants to take some action to employ, such as fastening and adjusting a seat belt; while passive restraints require no action by the vehicle occupants to be employed. Additional details of each of these subsystems of the SRS can be found elsewhere within this service information.

ACTIVE RESTRAINTS

The active restraints for this vehicle include

1. Child Restraint Anchors - All vehicles are equipped with three, fixed-position child seat upper tether anchors for the rear seating. These upper anchors are integral to the rear shelf panel. Two lower anchors are also provided for each outboard rear seating position. The lower anchors are integral to the rear seat Isofix mounting tube on the rear floor panel and are accessed from the front of the rear seat where the seat back meets the seat cushion.
2. Front Seat Belts - Both front seating positions are equipped with three-point seat belt systems employing a lower B-pillar mounted inertia latch-type emergency locking retractor, a height-adjustable upper B-pillar mounted turning loop, a fixed lower seat belt anchor latch plate secured to an anchor buckle on the inner sill near the base of the B-pillar and a traveling end-release seat belt buckle secured to a bracket near the back of the upper inboard seat track. The driver and passenger side front seat belt buckles include an integral seat belt switch that detects whether the front seat belts have been fastened.
3. Rear Seat Belts - All three rear seating positions are equipped with three-point seat belt systems. Each rear seating position belt employs a package shelf support mounted inertia latch-type emergency locking retractors. The outboard seating positions each have a fixed lower C-pillar mounted anchor, while the center seating position has a fixed lower anchor secured to the rear floor panel with the outboard left seating position seat belt buckle. All three rear seating positions have fixed end-release seat belt buckles secured to the rear floor panel.

Scheme 23

The passive restraints available for this vehicle include the following

1. Active Head Restraints - Inertia-based Active Head Restraints (AHR) are standard equipment for both front seating positions in this vehicle.
2. Dual Front Airbags - A multistage Driver AirBag (DAB) and front Passenger AirBag (PAB) are used in this vehicle. This airbag system consists of passive, inflatable, Supplemental Restraint System (SRS) components and vehicles with this equipment can be readily identified by the SRS - AIRBAG logo molded into the DAB trim cover in the center of the steering wheel and also into the PAB area on the top of the instrument panel above the glove box. Vehicles with the airbag system can also be identified by the airbag indicator, which will illuminate in the Instrument Cluster (IC) (also known as the Instrument Panel Cluster/IPC) from four to six seconds as a bulb test each time the status of the ignition switch transitions to On. Pyrotechnic-type driver and passenger front seat belt retractors and anchor buckle tensioners also work in conjunction with the dual front and side curtain airbags.
3. Knee Airbags - The front airbag system also includes driver and passenger front Knee AirBags (KAB) (also known as Inflatable Knee Blockers/IKB) that are located just below the lower instrument panel reinforcements. These airbags are also passive, inflatable, SRS components and vehicles with this equipment can be readily identified by the SRS - AIRBAG logo molded into the instrument panel trim just above each airbag location.
4. Front Seat Airbags - Front seat integrated Seat AirBags (SAB) (also known as pelvic and thoracic airbags) are standard equipment in these vehicles. This airbag system consists of passive, inflatable SRS components and vehicles with this equipment can be readily identified by a sewn tag with the SRS - AIRBAG logo located on the outboard side of the front seat back trim cover.
5. Rear Seat Airbags - Rear seat integrated Seat AirBags (SAB) (also known as pelvic and thoracic airbags) are optional equipment in these vehicles. This airbag system consists of passive, inflatable SRS components and vehicles with this equipment can be readily identified by a sewn tag with the SRS - AIRBAG logo located on the outboard sides of the rear seat cushion trim cover.
6. Side Curtain Airbags - Side curtain airbags (also known as a Side AirBag Inflatable Curtains/SABIC) are standard equipment in this vehicle. This airbag system consists of passive, inflatable SRS components and vehicles with this equipment can be readily identified by a molded identification SRS - AIRBAG logo located near the top of each B-pillar trim panel.

The SRS includes the following major components, which are described in further detail elsewhere in this service information

1. Active Head Restraints - One Active Head Restraint (AHR) is located atop each front seat back unit.
2. Airbag Indicator - The airbag indicator is integral to the Instrument Cluster (IC) (also known as the Instrument Panel Cluster/IPC), which is located on the instrument panel in front of the driver.
3. Clockspring - The clockspring is located near the top of the steering column, directly beneath the steering wheel.
4. Driver Airbag - The Driver AirBag (DAB) is located in the center of the steering wheel, beneath the DAB trim cover.
5. Front Impact Sensor - Two front impact sensors are used on vehicles equipped with dual front airbags, one left side and one right side. One sensor is located on the back side of each vertical member of the Front End Module (FEM) carrier, just outboard of each side of the cooling module.
6. Knee Airbags - This vehicle is equipped with Knee AirBags (KAB) (also known as Inflatable Knee Blockers/IKB). The KAB are mounted below the lower instrument panel reinforcements on each side of the vehicle.
7. Occupant Classification System - An Occupant Classification System (OCS) is standard equipment for this vehicle. The OCS includes a Seat Weight Sensor (SWS) bladder, a pressure hose and an Occupant Classification Module (OCM) integral to the calibrated passenger front seat cushion.
8. Occupant Restraint Controller - The Occupant Restraint Controller (ORC) is located on the floor panel transmission tunnel, between the dash panel and the instrument panel center stack support.
9. Passenger Airbag - The Passenger AirBag (PAB) is located in the instrument panel, beneath the instrument panel cover and above the glove box on the passenger side of the vehicle.
10. Front Seat Airbag - A front Seat AirBag (SAB) (also known as pelvic and thoracic airbag) is secured to each outboard front seat back frame, where it is concealed beneath the seat back trim cover and foam.
11. Rear Seat Airbag - The optional rear Seat AirBags (SAB) (also known as pelvic and thoracic airbags) are secured to each outboard end of the rear seat cushion pan, where they are concealed beneath the seat cushion trim cover and foam.
12. Seat Belt Tensioner - A seat belt tensioner is integral to both front seat belt retractors and both front seat belt anchor buckle units. The seat belt retractor tensioner units are secured to each lower inner B-pillar and are concealed behind the lower B-pillar trim. The seat belt anchor buckle tensioner units are located on the inner sill near the base of the B-pillar and are concealed behind the inner sill trim.
13. Seat Track Position Sensor - There are two Seat Track Position Sensors (STPS). One sensor is located on the inboard side of one of the seat adjuster tracks on both the driver and the passenger front seats.
14. Side Curtain Airbag - A standard equipment side curtain airbag (also known as a Side AirBag Inflatable Curtain/SABIC) is secured to each inside roof side rail above the headliner, and extends from the A-pillar to just beyond the C-pillar.
15. Side Impact Sensor - Six side impact sensors are used on vehicles equipped with side curtain airbags, three on each side of the vehicle. One acceleration-type sensor is located behind the B-pillar trim near the base of each B-pillar, and one acceleration-type sensor is located behind the quarter panel trim near the base of each C-pillar. One pressure-type sensor is located on each front poor hardware carrier panel, concealed behind each front door inside trim panel.

The ORC, the IPC and the OCM each contain a microcontroller and programming that allow them to communicate with each other using the Controller Area Network (CAN) data bus. This method of communication is used by the ORC for control of the airbag indicator in the IPC. Refer to COMMUNICATION, DESCRIPTION .

Hard wired circuitry connects the SRS components to each other through the electrical system of the vehicle. These hard wired circuits are integral to several wire harnesses, which are routed throughout the vehicle and retained by many different methods. These circuits may be connected to each other, to the vehicle electrical system, and to the SRS components through the use of a combination of soldered splices, splice block connectors, and many different types of wire harness terminal connectors and insulators. Refer to the appropriate wiring information. The wiring information includes wiring diagrams, proper wire and connector repair procedures, further details on wire harness routing and retention, as well as pin out and location views for the various wire harness connectors, splices and grounds.

The Supplemental Restraint System (SRS) is comprised of two primary subsystems: Active Restraints and Passive Restraints. Additional operational details on each of these subsystems of the SRS can be found elsewhere within this service information.

The primary passenger restraints in this or any other vehicle are the standard equipment factory-installed seat belts and child restraint anchors. Seat belts and child restraint anchors are referred to as an active restraint because the vehicle occupants are required to physically fasten and properly adjust these restraints in order to benefit from them.

PASSIVE RESTRAINTS

The passive restraints are referred to as Supplemental Restraint System (SRS) components because they were designed and are intended to enhance the protection for the occupants of the vehicle only when used in conjunction with the seat belts. They are referred to as passive restraints because the vehicle occupants are not required to do anything to make them operate; however, the vehicle occupants must be wearing their seat belts in order to obtain the maximum safety benefit from the factory-installed SRS components. In addition, each front seat occupant must have their Active Head Restraint (AHR) unit properly adjusted in order to obtain its maximum safety benefit.

The SRS electrical circuits are continuously monitored and controlled by a microcontroller and software contained within the Occupant Restraint Controller (ORC). An airbag indicator in the Instrument Cluster (IC) (also known as the Instrument Panel Cluster/IPC) illuminates from four to six seconds as a bulb test each time the status of the ignition switch transitions to On or Start. Following the bulb test, the airbag indicator is turned On or Off by the ORC to indicate the status of the SRS. If the airbag indicator comes On at any time other than during the bulb test, it indicates that there is a problem in the SRS electrical circuits. Such a problem may cause airbags not to deploy when required, or to deploy when not required.

Deployment of the SRS components depends upon the angle and severity of an impact. Deployment is not based upon vehicle speed; rather, deployment is based upon the rate of deceleration as measured by the forces of gravity (also known as G forces) upon the acceleration-type impact sensors, or by a pressure wave within a door as measured by the pressure-type impact sensor. When an impact is severe enough, the microcontroller within the ORC signals the inflator of the appropriate airbag units to deploy their airbag cushions. The Occupant Classification System (OCS) monitors the passenger side front seat to determine whether or not the passenger side front seat is occupied and, if the seat is occupied, classifies the size of the occupant. The Occupant Classification Module (OCM) then provides an additional logic input that is used by the ORC to determine the appropriate force with which the Passenger AirBag (PAB) and seat belt tensioner should be deployed.

The front seat belt retractor tensioners, front seat belt anchor buckle tensioners, the front seat belt adaptive load limiters and the Knee AirBags (KAB) (also known as the Inflatable Knee Blockers/IKB) are provided with a deployment signal by the ORC in conjunction with the front airbags. The side curtain airbags (also known as the Side AirBag Inflatable Curtains/SABIC) and the Seat AirBags (SAB) (also known as pelvic and thoracic airbags) are provided with a deployment signal individually by the ORC based upon a side impact sensor input for the same side of the vehicle.

During a frontal vehicle impact, the KAB units work in concert with properly fastened and adjusted seat belts to restrain both the driver and the front seat passenger in the proper position for an airbag deployment. The KAB units also absorb and distribute the crash energy from the driver and the front seat passenger to the structure of the instrument panel. The seat belt tensioners remove the slack from the front seat belts to provide further assurance that the driver and front seat passenger are properly positioned and restrained for an airbag deployment. The adaptive load limiters for the front seat belts allow the ORC to control the belt pressure applied to the chests of the front seat occupants based upon the impact sensor inputs.

Typically, the vehicle occupants recall more about the events preceding and following a collision than they do of an airbag deployment itself. This is because the airbag deployment and deflation occur very rapidly. In a typical 48 kilometer-per-hour (30 mile-per-hour) barrier impact, from the moment of impact until the airbags are fully inflated takes about 40 milliseconds. Within one to two seconds from the moment of impact, the airbags are almost entirely deflated. The times cited for these events are approximations, which apply only to a barrier impact at the given speed. Actual times will vary somewhat, depending upon the vehicle speed, impact angle, severity of the impact and the type of collision.

When the ORC monitors a problem in any of the SRS circuits or components, including the seat belt tensioners and adaptive load limiter units, it stores a fault code or Diagnostic Trouble Code (DTC) in its memory circuit and sends an electronic message to the IC to turn On the airbag indicator. The hard wired circuits between components related to the SRS may be diagnosed using conventional diagnostic tools and procedures. Refer to the appropriate wiring information. The wiring information includes wiring diagrams, proper wire and connector repair procedures, details of wire harness routing and retention, connector pin out information and location views for the various wire harness connectors, splices and grounds.

However, conventional diagnostic methods will not prove conclusive in the diagnosis of the SRS or the electronic controls and communication between other modules and devices that provide features of the SRS. The most reliable, efficient and accurate means to diagnose the SRS or the electronic controls and communication related to SRS operation, as well as the retrieval or erasure of a DTC requires the use of a diagnostic scan tool and may also require the use of the SRS Load Tool special tool along with the appropriate Load Tool Jumpers and Adapters. Refer to the appropriate diagnostic information.

HANDLING NON-DEPLOYED SUPPLEMENTAL RESTRAINTS

At no time should any source of electricity be permitted near the inflator on the back of a non-deployed airbag or seat belt tensioner. When carrying a non-deployed airbag, the trim cover or airbag cushion side of the unit should be pointed away from the body to minimize injury in the event of an accidental deployment. If the airbag unit is placed on a bench or any other surface, the trim cover or airbag cushion side of the unit should be face up to minimize movement in the event of an accidental deployment.

When handling a non-deployed seat belt tensioner, take proper care to keep fingers out from under the retractor or buckle cover and away from the seat belt webbing or cable where it exits from the retractor or buckle cover. In addition, the Supplemental Restraint System (SRS) should be disarmed whenever any steering wheel, steering column, seat belt tensioner, airbag, impact sensor or instrument panel components require diagnosis or service. Failure to observe this warning could result in accidental airbag deployment and possible personal injury.

All damaged, ineffective or non-deployed airbags and seat belt tensioners which are replaced on vehicles are to be handled and disposed of properly. If an airbag or seat belt tensioner unit is ineffective or damaged and non-deployed, refer to the Hazardous Substance Control System for information regarding the potentially hazardous properties of the subject component and the proper safe handling procedures. Then dispose of all non-deployed and deployed airbags and seat belt tensioners in a manner consistent with state, provincial, local and federal regulations.

SERVICE AFTER A SUPPLEMENTAL RESTRAINT SYSTEM DEPLOYMENT

Any vehicle which is to be returned to use following a Supplemental Restraint System (SRS) component deployment must have the deployed restraints replaced. In addition, the following guidelines MUST be observed.

1. Following ANY major vehicle impact damage in the vicinity of an impact sensor or the ORC - It is critical that the mounting surfaces and mounting brackets for the Occupant Restraint Controller (ORC), front impact sensors and side impact sensors located within the proximity of the impact damage be closely inspected and restored to their original conditions. Because the ORC and each impact sensor are used by the SRS to monitor or confirm the direction and severity of a vehicle impact, improper orientation or insecure fastening of these components may cause airbags not to deploy when required, or to deploy when not required.
2. If an active head restraint is deployed - An inertia-based Active Head Restraint (AHR) unit that is undamaged following a deployment may be reset. These units are designed with the intention of reuse.
3. If the driver airbag is deployed - If the Driver AirBag (DAB) has been deployed, the clockspring and the steering column must also be replaced.
4. If the knee airbags are deployed - If the Knee AirBags (KAB) (also known as Inflatable Knee Blockers/IKB) have been deployed, the instrument panel steering column opening cover (left side) and the glove box (right side) must also be replaced.
5. If the passenger airbag is deployed - If the Passenger AirBag (PAB) has been deployed, the instrument panel upper trim cover must also be replaced.
6. If a front seat airbag is deployed - If a front Seat AirBag (SAB) (also known as a pelvic and thoracic airbag) has been deployed, the front seat back frame, the front seat back foam and the front seat back trim cover on the same side of the vehicle as the deployed airbag must also be replaced.
7. If a rear seat airbag is deployed - If a rear Seat AirBag (SAB) (also known as a pelvic and thoracic airbag) has been deployed, the rear seat cushion pan, the rear seat cushion foam and the rear seat cushion trim cover must also be replaced.
8. If a seat belt tensioner is deployed - The seat belt retractor and anchor buckle tensioners as well as the adaptive load limiters are deployed in conjunction with the front airbags, but can also be deployed with front Seat AirBag (SAB) (also known as a pelvic and thoracic airbag) or side curtain airbags (also known as Side AirBag Inflatable Curtains/SABIC). The seat belt tensioners must be replaced if either front airbag has been deployed, and must be inspected if either front SAB or side curtain airbag has been deployed.
9. If a side curtain airbag is deployed - If a side curtain airbag (also known as a Side AirBag Inflatable Curtain/SABIC) has been deployed, the headliner as well as the deploy brackets on the upper B and C-pillars and the trim on the upper A, B and C-pillars on the same side of the vehicle as the deployed airbag must also be replaced. On vehicles with an optional sunroof, the sunroof drain tubes and hoses must be closely inspected following a side curtain airbag deployment.

The components identified with the deployed SRS components in the preceding list are not intended for reuse and will be damaged or weakened as a result of an airbag deployment, which may or may not be obvious during a visual inspection. All other vehicle components should be closely inspected following any SRS component deployment, but are to be replaced only as required by the extent of the visible damage incurred.

SQUIB CIRCUIT DAMAGE

In addition to the preceding guidelines, be aware that the heat created by the initiator during an airbag or tensioner deployment will cause collateral damage to the connected wiring (squib circuits) and connector insulators. There are two methods by which an airbag or seat belt tensioner may be connected to the vehicle electrical system. The first method involves a short pigtail harness and connector insulator that are integral to the airbag or tensioner unit and are replaced as a unit with the service replacement airbag or seat belt tensioner. This connection method typically requires no additional wiring repair following a deployment.

However, the second connection method involves a wire harness takeout and connector insulator that are connected directly to the airbag or tensioner initiator or squib. These direct-connect type take outs and connector insulators MUST be repaired following an airbag or seat belt tensioner deployment using the approved Supplemental Restraint System Wiring Repairs procedure.

AIRBAG SQUIB STATUS

Multistage airbags with multiple initiators (squibs) must be checked to determine that all squibs were used during the deployment event. The Driver AirBag (DAB) and Passenger AirBag (PAB) in this vehicle are deployed by electrical signals generated by the Occupant Restraint Controller (ORC) through the driver or passenger squib 1 and squib 2 circuits to the two initiators in the airbag inflators. Typically, both initiators are used and all potentially hazardous chemicals are burned during an airbag deployment event. However, it is possible for only one initiator to be used; therefore, it is always necessary to confirm that both initiators have been used in order to avoid the improper handling or disposal of potentially live pyrotechnic or hazardous materials. The following procedure should be performed using a diagnostic scan tool to verify the status of both airbag squibs before either deployed airbag is removed from the vehicle for disposal.

1. Be certain that the diagnostic scan tool contains the latest version of the proper diagnostic software. Connect the scan tool to the 16-way Data Link Connector (DLC). The DLC is located on the driver side lower edge of the instrument panel, outboard of the steering column.
2. Transition the ignition switch to the On status.
3. Using the scan tool, read and record the active (current) Diagnostic Trouble Code (DTC) data.

Using the active DTC information, refer to the Airbag Squib Status table below to determine the status of both DAB squibs and both PAB squibs.

AIRBAG SQUIB STATUS

Note. If none of the Driver or Passenger Squib 1 or 2 open are active codes, the status of the airbag squibs is unknown. In this case the airbag should be handled and disposed of as if the squibs were both live.

Scheme 24

Following a Supplemental Restraint System (SRS) component deployment, the vehicle interior will contain a powdery residue. This residue consists primarily of harmless particulate by-products of the small pyrotechnic charge that initiates the propellant used to deploy a SRS component. However, this residue may also contain traces of sodium hydroxide powder, a chemical by-product of the propellant material that is used to generate the inert gas that inflates the airbag. Since sodium hydroxide powder can irritate the skin, eyes, nose, or throat, be certain to wear safety glasses, rubber gloves, and a long-sleeved shirt during cleanup.

Scheme 25

1. Begin the cleanup by using a vacuum cleaner to remove any residual powder from the vehicle interior. Clean from outside the vehicle and work your way inside, so that you avoid kneeling or sitting on a non-cleaned area.
2. Be certain to vacuum the heater and air conditioning outlets as well. Run the heater and air conditioner blower on the lowest speed setting and vacuum any powder expelled from the outlets. CAUTION: Deployed front airbags having two initiators (squibs) in the airbag inflator may or may not have live pyrotechnic material within the inflator. Do not dispose of these airbags unless you are certain of complete deployment. Refer to the «AIRBAG SQUIB STATUS»(ref-646225-S01950776992014072800000) heading within this information. All damaged, ineffective, or non-deployed Supplemental Restraint System (SRS) components which are replaced on vehicles are to be handled and disposed of properly. If an airbag or seat belt tensioner unit is ineffective or damaged and non-deployed, refer to the Hazardous Substance Control System for information regarding the potentially hazardous properties of the subject component and the proper safe handling procedures. Then dispose of all non-deployed and deployed airbags and seat belt tensioners in a manner consistent with state, provincial, local and federal regulations.
3. Next, remove the deployed SRS components from the vehicle. Refer to the appropriate service removal procedures.
4. You may need to vacuum the interior of the vehicle a second time to recover all of the powder.

SUPPLEMENTAL RESTRAINT STORAGE

Airbags and seat belt tensioners must be stored in their original, special container until they are used for service. Also, they must be stored in a clean, dry environment away from sources of extreme heat, sparks and high electrical energy. Always place or store any airbag on a surface with its trim cover or airbag cushion side facing up, to minimize movement in case of an accidental deployment.

REPAIR PROCEDURE

Scheme 32

The horizontal surface of the instrument panel top pad above the glove box is the most visible part of the Passenger Airbag (PAB). The PAB door is integral to the top of the instrument panel top pad forward of and above the glove box on the instrument panel in front of the front seat passenger seating position.

Located below the PAB door area of the instrument panel top pad, the molded thermoplastic PAB retainer or chute is secured to the underside of the top pad. The retainer defines the PAB door breakout area of the top pad and serves as the receptacle for the PAB cushion and housing. Numerous small window openings on the forward and rearward flanges of the receptacle receive mating hook formations stamped into the airbag housing, which locate and secure the housing to the top pad.

The PAB unit is also secured by a mounting bracket (5) and two screws to the instrument panel structural support. The PAB unit used in this vehicle is a multistage type that complies with revised federal airbag standards to deploy with less force than those used in some prior vehicles. The PAB unit consists of a stamped metal housing (1), the airbag cushion (2), an active vent tether release (3) (domestic market vehicles only) and the two-stage airbag inflator (4). The PAB inflator, the mounting bracket and the airbag cushion are secured to the housing by four studs and four nuts. The airbag housing contains the folded airbag cushion and the cushion retainer. An approximately 66 centimeter (26 inch) wide by 76 centimeter (30 inch) high rectangular fabric cushion is used.

The PAB inflator is a non-azide, pyrotechnic-type unit that is secured to and sealed within the airbag housing. Three dedicated take outs and yellow connectors of the PAB wire harness with keyed, color-coded insulators connect the two inflator initiators and the active vent tether release to a yellow, 6 way connector secured to the mounting bracket. A dedicated take out and connector of the instrument panel wire harness connects the PAB to the vehicle electrical system.

The PAB cannot be repaired, and must be replaced if deployed, ineffective or in any way damaged. The PAB door and chute or retainer are serviced only as a unit with the instrument panel top pad. If the PAB is deployed, the top pad must also be replaced.

FRONT

Each front Seat AirBag (SAB) (also known as a pelvic and thoracic airbag) is deployed individually by an electrical signal generated by the Occupant Restraint Controller (ORC) to which it is connected through left or right front SAB line 1 and line 2 (or squib) circuits. When the ORC sends the proper electrical signal to the pyrotechnic-type SAB inflator, the electrical energy generates enough heat to initiate a small pyrotechnic charge which ignites chemical pellets within the inflator.

Once ignited, these chemical pellets burn rapidly and produce a large quantity of inert gas. The inflator is sealed to the SAB cushion and a diffuser in the inflator directs all of the inert gas into the folded SAB cushion, causing the cushion to inflate. As the cushion inflates it will split the fabric wrap, the pouch (intensifier) integral to the seat back trim cover and the outboard side of the seat back trim cover. The cushion then expands into the area between the outboard side of the front seat and the front door to form a cushion to protect the front seat occupant during a side impact collision.

Following the SAB deployment, the cushion slowly deflates by venting the inert gas through the loose weave of the cushion fabric, and through a vent in the cushion. After venting is achieved, the deflated cushion hangs down loosely from the outboard side of the front seat back.

The ORC monitors the condition of the front SAB through circuit resistance, and will illuminate the airbag indicator in the Instrument Panel Cluster (IPC) and store a Diagnostic Trouble Code (DTC) for any fault that is detected. Proper diagnosis of the front SAB inflator and squib circuits requires the use of a diagnostic scan tool and may also require the use of the SRS Load Tool special tool along with the appropriate Load Tool Jumpers and Adapters. Refer to the appropriate diagnostic information.

REAR

Each rear Seat AirBag (SAB) (also known as a pelvic and thoracic airbag) is deployed individually by an electrical signal generated by the Occupant Restraint Controller (ORC) to which it is connected through left or right rear SAB line 1 and line 2 (or squib) circuits. The hybrid-type inflator assembly for each SAB contains a small canister of highly compressed inert gas. When the ORC sends the proper electrical signal to the SAB inflator, the electrical energy creates enough heat to ignite chemical pellets within the inflator.

Once ignited, these chemicals burn rapidly and produce the pressure necessary to rupture a containment disk in the inert gas canister. The inflator and inert gas canister are sealed and connected so that all of the released gas is directed into the folded SAB cushion, causing the cushion to inflate. As the cushion inflates it will split the fabric wrap, the intensifier and the outboard side of the seat cushion trim cover, then expand into the area between the outboard side of the rear seat and the rear door to form a cushion to protect the rear seat occupant during a side impact collision.

Following the rear SAB deployment, the cushion slowly deflates by venting the inert gas through the loose weave of the cushion fabric and through a vent in the cushion. After venting is achieved, the deflated cushion hangs down loosely from the outboard side of the rear seat cushion.

The ORC monitors the condition of the rear SAB through circuit resistance, and will illuminate the airbag indicator in the Instrument Panel Cluster (IPC) and store a Diagnostic Trouble Code (DTC) for any fault that is detected. Proper diagnosis of the rear SAB inflator and squib circuits requires the use of a diagnostic scan tool and may also require the use of the SRS Load Tool special tool along with the appropriate Load Tool Jumpers and Adapters. Refer to the appropriate diagnostic information.

Scheme 38

Side curtain airbags (also known as Side AirBag Inflatable Curtains/SABIC) are standard factory-installed equipment for this vehicle. These airbags are passive, inflatable, Supplemental Restraint System (SRS) components. The side curtain airbag system is designed to reduce injuries to the vehicle occupants in the event of a side impact collision. Each side curtain airbag cushion provides full coverage of the side glass on the same side of the vehicle as the monitored impact.

Each vehicle is equipped with two individually controlled side curtain airbag units. These side curtain airbag units are concealed and mounted above the headliner where they are each secured to one of the roof side rails. Each folded airbag cushion is contained within a fabric wrap and suspended from four plastic clamp hangers that are spaced along the roof rail from the A-pillar at the front of the vehicle to the C-pillar at the rear of the vehicle. A long tether (1) extends down the A-pillar from the front of the side curtain airbag cushion, while a shorter tether (4) extends back to over the C-pillar. The end of each tether is secured to a slot in the sheet metal with a plastic push-in fastener.

The hybrid-type inflator (3) for each side curtain airbag is secured to the roof rail above the B-pillar and is connected to the airbag cushion by a long tubular manifold. The inflator bracket has an integral hook formation (2) on one end. The inflator is initially hung from the roof rail by the hook formation, then plastic push-in fasteners secure the clamp hangers and the body of the airbag cushion to the roof rail and to stamped metal deploy brackets at the top of the B-pillar and C-pillar. Finally, the entire assembly is secured with screws (5) to the roof rail.

The airbag inflator is connected to the vehicle electrical system through a dedicated take out and connector of the body wire harness near the top of the B-pillar. The body wire harness connects the side curtain airbag unit to the Occupant Restraint Controller (ORC).

The side curtain airbag units cannot be adjusted or repaired and must be replaced if deployed, ineffective or in any way damaged. Once a side curtain airbag has been deployed, the complete side curtain airbag unit, the deploy brackets, the headliner, the A-pillar trim as well as all other visibly damaged components must be replaced.

The inner surface of the clockspring rotor hub has keyway features that are engaged by lug features on the outer circumference of the steering wheel hub. These interlocking features allow the steering wheel to drive the clockspring and also unlock the clockspring rotor when the steering wheel has been properly installed.

Wound around the rotor spool within the case are long ribbon-like tapes that consist of several thin copper wire leads sandwiched between two thin plastic membranes. The outer end of the tapes terminate at the terminal pins that are housed within a connector receptacle integral to the SCCM mounting housing and face the instrument panel, while the inner ends of the tapes terminate at the pigtail wires and connector receptacle on the hub of the clockspring rotor that face the steering wheel. The outer surface of the rotor spool hub within the clockspring case also has the integral lobes of the turn signal cancel cam.

The clockspring also has an interconnect with terminal pins that engage a mating interconnect receptacle integral to the SCCM mounting housing. This interconnect features several circuits which pass through the clockspring to connect the SCM to the vehicle electrical system.

The clear plastic clockspring rotor has an outer band that has a translucent or frosted appearance except for a small, clear inspection window area. The clockspring tape has several black squares that are only visible through the clear inspection window when the clockspring is properly centered. If these squares are not visible through the inspection window, clockspring centering has been compromised and the entire clockspring must be replaced with a new unit.

The service replacement clockspring is shipped with the clockspring pre-centered and with a red molded plastic locking tab installed. The locking tab secures the centered clockspring rotor to the clockspring case during shipment and handling, but must be removed after the clockspring is installed on the steering column and before the steering wheel can be installed. The clockspring cannot be repaired. If the clockspring is ineffective, damaged, if clockspring centering is compromised or if the Driver AirBag (DAB) has been deployed the entire clockspring unit must be replaced. Refer to CLOCKSPRING, STANDARD PROCEDURE .

STANDARD PROCEDURE - CLOCKSPRING CENTERING

Scheme 52

Like the clockspring in a timepiece, the clockspring tape has travel limits and can be damaged by being wound too tightly during full stop-to-stop steering wheel rotation. To prevent this from occurring, the clockspring is centered when it is installed on the steering column. Centering the clockspring indexes the clockspring tape to the movable steering components so that the tape can operate within its designed travel limits. However, if the steering shaft is disconnected from the steering gear, the clockspring rotor spool can change position relative to the fixed steering components.

Clockspring centering must always be confirmed by viewing the inspection window (2) on the clockspring rotor (1). If the black squares (3) on the clockspring tape are not visible through the inspection window, clockspring centering has been compromised and the clockspring must be replaced with a new unit. Refer to CLOCKSPRING, REMOVAL .

The service replacement clockspring is shipped pre-centered and with a red plastic locking tab installed. This locking tab should not be removed until the clockspring has been properly installed on the steering column. If the locking tab is removed before the clockspring is installed on a steering column, clockspring centering must be confirmed by viewing the black squares on the clockspring tape through the inspection window on the clockspring rotor. If the black squares of the clockspring tape are not visible through the inspection window, clockspring centering has been compromised and the clockspring must be replaced with a new unit. Refer to CLOCKSPRING, INSTALLATION .

IMPACT SENSORS

Remote or satellite impact sensors are mounted in various strategic locations of the vehicle. These sensors are mounted remotely from the impact sensor that is internal to the Occupant Restraint Controller (ORC). Sensors at the front of the vehicle provide an additional logic input for use by the Occupant Restraint Controller (ORC) to control the front airbags and the seat belt pretensioners. Sensors on each side of the vehicle provide an additional logic input for use by the ORC to control the side curtain airbags, seat airbags and the seat belt pretensioners. Two types of sensors are used in this vehicle. They are the acceleration-type and the pressure-type, which are described in further detail elsewhere within this service information.

Scheme 56

Remote or satellite acceleration-type impact sensors (1) are mounted in various locations in the vehicle. These sensors are mounted remotely from the impact sensor that is internal to the Occupant Restraint Controller (ORC). Sensors at the front of the vehicle provide an additional logic input for use by the ORC to control the front airbags and the seat belt pretensioners. Sensors on each side of the vehicle provide an additional logic input for use by the ORC to control the side curtain airbags, the seat belt pretensioners and the seat (also known as pelvic and thorax) airbags.

Although the front and side acceleration-type impact sensors are similar in appearance and construction, they may not be interchangeable. The front impact sensors may monitor acceleration forces on a different axis than those monitored by the side impact sensors. Each sensor is secured to its mounting location by a single screw or by a nut and a weld stud. The front sensors are located on each vertical support member of the Front End Module (FEM) carrier between the cooling module and the front lamp unit. A side sensor is located on each inner B-pillar and each inner C-pillar and concealed behind the interior trim.

Each sensor housing has an integral connector receptacle (3), an integral locator pin with a latch feature (4) and an integral mounting hole with a metal sleeve (2) to provide crush protection. A cavity in the center of the molded plastic impact sensor housing contains the electronic circuitry of the sensor which includes an electronic communication chip and an electronic acceleration sensor. Potting material fills the housing, which is laser welded to seal and protect the internal electronic circuitry and components.

The front impact sensors are each connected to the vehicle electrical system through dedicated take outs and connectors of the headlamp and dash wire harness, while the side impact sensors are connected through dedicated take outs and connectors of the body wire harness.

The acceleration-type impact sensors cannot be repaired or adjusted and, if damaged or ineffective, they must be replaced.

Scheme 57

Two pressure-type front door side impact sensors (2) are used on this vehicle, one each for the left and right sides of the vehicle. These sensors are mounted remotely from the impact sensor that is internal to the Occupant Restraint Controller (ORC). Each side sensor is secured with two screws and is sealed by a resilient gasket (1) to the front door hardware module carrier on the front door inner panel. The sensors are concealed behind the front door trim panel within the passenger compartment.

The right and left front door side impact sensors are identical in construction and calibration. The impact sensor housing has an integral connector receptacle (3), two integral mounting tabs, and an integral hood-like water shield (4). The water shield extends through a hole in the front door module carrier into the interior of the door cavity and protects the sensor orifice from contamination.

A cavity in the center of the molded plastic impact sensor housing contains the electronic circuitry of the sensor, which includes an electronic communication chip and the pressure sensor. The housing cavity is filled with a potting material to seal and protect the internal electronic circuitry and components. The pressure-type side impact sensors are each connected to the vehicle electrical system through a dedicated take out and connector of the front door wire harness.

The pressure-type side impact sensors cannot be repaired or adjusted and, if damaged or ineffective, they must be replaced.

Two types of impact sensors are used in this vehicle. They are the acceleration-type and the pressure-type. Additional operational details of each of these sensor types is described in further detail elsewhere within this service information.

ACCELERATION TYPE

The acceleration-type impact sensors are electronic accelerometers that sense the rate of vehicle deceleration, which provides verification of the direction and severity of an impact. Each sensor also contains an electronic communication chip that allows the unit to communicate the sensor status as well as sensor fault information to the microcontroller within the Occupant Restraint Controller (ORC).

The ORC microcontroller continuously monitors all of the Supplemental Restraint System (SRS) electrical circuits to determine the system readiness. If the ORC detects a monitored system fault, it sets a Diagnostic Trouble Code (DTC) and controls the airbag indicator operation accordingly. The impact sensors each receive battery current and ground through dedicated left and right sensor plus and minus circuits from the ORC. The impact sensors and the ORC communicate by modulating the voltage in the sensor plus circuit.

The hard wired circuits between the impact sensors and the ORC may be diagnosed using conventional diagnostic tools and procedures. Refer to the appropriate wiring information. However, conventional diagnostic methods will not prove conclusive in the diagnosis of the impact sensors or the electronic controls and communication between other modules and devices that provide some features of the SRS. The most reliable, efficient and accurate means to diagnose the acceleration-type impact sensors or the electronic controls and communication related to impact sensor operation requires the use of a diagnostic scan tool. Refer to the appropriate diagnostic information.

PRESSURE TYPE

The pressure-type front door side impact sensors recognize a side impact in the front door area by monitoring changes in pressure within the front door cavity. A sudden pressure wave is created as the door collapses during an impact event. Each sensor also contains an electronic communication chip that allows the unit to communicate the sensor status as well as sensor fault information to the microcontroller within the Occupant Restraint Controller (ORC).

The ORC microcontroller continuously monitors all of the Supplemental Restraint System (SRS) electrical circuits to determine the system readiness. If the ORC detects a monitored system fault, it sets a Diagnostic Trouble Code (DTC) and controls the airbag indicator operation accordingly. The impact sensors each receive battery current and ground through dedicated left and right sensor plus and minus circuits from the ORC. The impact sensors and the ORC communicate by modulating the current in the sensor plus circuit.

The hard wired circuits between the pressure-type front door side impact sensors and the ORC may be diagnosed using conventional diagnostic tools and procedures. Refer to the appropriate wiring information. However, conventional diagnostic methods will not prove conclusive in the diagnosis of the impact sensors or the electronic controls and communication between other modules and devices that provide features of the SRS. The most reliable, efficient and accurate means to diagnose the pressure-type impact sensors or the electronic controls and communication related to impact sensor operation requires the use of a diagnostic scan tool. Refer to the appropriate diagnostic information.
