Scheme 35

The passive restraints available for this vehicle include the following

1. Dual Front Airbags - Multistage driver and front passenger airbags 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 driver airbag trim cover in the center of the steering wheel and also into the passenger airbag door on the top of the instrument panel trim cover above the upper glove box or storage bin opening. Vehicles with the airbag system can also be identified by the airbag indicator, which will illuminate in the ElectroMechanical Instrument Cluster (EMIC) (also known as the Cab Compartment Node/CCN) from four to six seconds as a bulb test each time the ignition switch is turned to the ON position. A pyrotechnic-type seat belt tensioner is also integral to the front outboard seat belt retractors to work in conjunction with the dual front airbags.
2. Side Curtain Airbags - Side curtain airbags are standard equipment for this vehicle when it is also equipped with dual front airbags. This airbag system consists of passive, inflatable, SRS components and vehicles with this equipment can be readily identified by a molded identification trim button with the SRS - AIRBAG logo located at the top of each B-pillar trim (all models) and C-pillar trim (quad or crew cab and mega cab only) near the headliner.

Scheme 36

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

1. Airbag Indicator - The airbag indicator is integral to the ElectroMechanical Instrument Cluster (EMIC) (also known as the Cab Compartment Node/CCN), which is located on the instrument panel in front of the driver.
2. Clockspring - The clockspring is located near the top of the steering column, directly beneath the steering wheel.
3. Driver Airbag (3) - The driver airbag is located in the center of the steering wheel horn pad, beneath the driver airbag trim cover.
4. Driver Knee Blocker - The driver knee blocker is a structural unit secured to the back side of and integral to the instrument panel steering column opening cover.
5. Front Impact Sensor (1) - Two front impact sensors are used, one left side and one right side. One sensor is located on the back side of each end of the lower radiator support cross member on each side of the cooling module and below the inboard side of each front lamp unit.
6. Occupant Restraint Controller (5) - The Occupant Restraint Controller (ORC) is located on a mounting bracket on the floor panel transmission tunnel below the center section of the front seat, or under the center floor console, as the vehicle is equipped.
7. Passenger Airbag (2) - The passenger airbag is located in the instrument panel, beneath the passenger airbag door integral to the top of the instrument panel trim cover just forward of the upper glove box or storage bin on the passenger side of the vehicle.
8. Passenger Knee Blocker - The passenger knee blocker is a structural reinforcement that is integral to and concealed within the lower glove box door.
9. Seat Belt Tensioner (6) - A seat belt tensioner is integral to both front outboard seat belt retractor units. The seat belt retractor tensioner units are secured to the right and left inner B-pillars and concealed beneath the lower B-pillar trim.
10. Side Curtain Airbag (8) - A side curtain airbag is secured to each inside roof side rail above the headliner, and extends from the A-pillar to near the cab back.
11. Side Impact Sensor - Up to six side impact sensors are used on vehicles with side curtain airbags, up to three on each side of the vehicle. One pressure-type sensor (4) is located on each right and left front door module carrier behind the front door trim panel on some vehicles. In addition, an acceleration-type sensor (7) is located on each inner B-pillar behind the lower B-pillar trim on all models, while quad or crew cab and mega cab models also have one acceleration-type sensor on each inner C-pillar behind the lower C-pillar trim.

The ORC and the EMIC each contain a microprocessor 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 EMIC. 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 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 a Supplemental Restraint System (SRS) 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.

The SRS electrical circuits are continuously monitored and controlled by a microprocessor and software contained within the Occupant Restraint Controller (ORC). An airbag indicator in the ElectroMechanical Instrument Cluster (EMIC) (also known as the Cab Compartment Node/CCN) illuminates from four to six seconds as a bulb test each time the ignition switch is turned to the ON or START positions. 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 (G force) upon the acceleration-type impact sensors, or by a pressure wave within a front door as measured by the pressure-type impact sensor. When an impact is severe enough, the microprocessor in the ORC signals the inflator of the appropriate airbag units to deploy their airbag cushions. The outboard front seat belt retractor tensioners are provided with a deployment signal by the ORC in conjunction with the front airbags. The side curtain 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 knee blockers work in concert with properly fastened and adjusted seat belts to restrain both the driver and the right front seat passenger in the proper position for an airbag deployment. The knee blockers also absorb and distribute the crash energy from the driver and the right front seat passenger to the structure of the instrument panel. The seat belt tensioners remove the slack from the outboard front seat belts to provide further assurance that the driver and right front seat passenger are properly positioned and restrained for an airbag deployment.

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, it stores a fault code or Diagnostic Trouble Code (DTC) in its memory circuit and sends an electronic message to the EMIC 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 or 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. 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.

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.

SERVICE AFTER A SUPPLEMENTAL RESTRAINT 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 the driver airbag is deployed - If the driver airbag has been deployed, the clockspring and the steering column must be replaced.
3. If the passenger airbag is deployed - If the passenger airbag has been deployed, the instrument panel trim cover must also be replaced.
4. If a seat belt tensioner is deployed - The seat belt tensioners are deployed in conjunction with the front airbags, but can also be deployed with side curtain airbags. The seat belt tensioners must be replaced if either front airbag has been deployed, and must be inspected if either side curtain airbag has been deployed.
5. If a side curtain airbag is deployed - If a side curtain airbag has been deployed, the headliner as well as the upper A, B and C-pillar trim 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.

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 and passenger airbags 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. Turn the ignition switch to the ON position.
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 to determine the status of both driver and passenger airbag squibs.

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 37

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 38

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-457806-S36821126102012030200000) 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.

The clockspring (5) for this vehicle is secured near the top of the steering column below the steering wheel. The clockspring also includes an integral, internal turn signal cancel cam, a Steering Angle Sensor (SAS) and, on vehicles equipped with the optional heated steering wheel, a set of internal slip rings. All of these components are serviced as a unit with the clockspring. The clockspring also supports the multi-function switch (1), the Steering Control Module (SCM) internal to the multi-function switch housing (2) and a blank filler (7) for, or the optional adjustable pedal switch, which are secured to the clockspring mounting bracket with integral keyways and latch feature provisions. The multi-function switch, adjustable pedal switch blank filler or the adjustable pedal switch are available for individual service replacement. When combined, these components are sometimes referred to as the Steering Column Control Module (SCCM).

The clockspring case includes integral tabs at the top and bottom for mounting the unit to the steering column housing with two screws, as well as integral provisions for mounting and supporting the multi-function switch, adjustable pedal switch, SAS and heated steering wheel slip rings. The SAS integral to the clockspring includes an electronic circuit board and a microprocessor, which allows it to communicate with other electronic modules in the vehicle over the Controller Area Network (CAN) data bus. The SAS circuitry is contained within a flat, molded plastic case that is secured to the lower surface of the clockspring case that hangs below the steering column.

Within the plastic clockspring case is a spool-like molded plastic rotor with a large exposed hub and an integral turn signal cancel cam. The upper surface of the rotor hub has a large center hole, an engagement dowel or drive pin, a single sleeve containing two short driver airbag squib pigtail wires with connectors, and a connector receptacle that faces toward the steering wheel. On vehicles equipped with the optional heated steering wheel, a third heated steering wheel pigtail wire and connector exits the upper surface of the rotor.

Service replacement clocksprings are shipped pre-centered and with a molded plastic locking pin (4) that snaps into a receptacle on the rotor. The locking pin secures the centered clockspring rotor to the clockspring case and the SAS during shipment and handling, but must be removed from the clockspring after it is installed on the steering column. The locking pin is a one time component and cannot be reinstalled once it has been removed. The clockspring must be replaced if proper centering has been compromised or the tape may be damaged and Diagnostic Trouble Codes (DTCs) or faults may be set within the SAS.

Scheme 51

The lower surface of the clockspring case (1) facing toward the instrument panel includes two receptacles on the left for mounting the multi-function switch (2) and the optional adjustable pedal switch (3). There are two integral connector receptacles (4) on the left lower corner of the clockspring case. Clocksprings with a SAS (5) also have a dedicated connector (6) near the right lower corner of that unit. Vehicles equipped with the optional heated steering wheel also have a dedicated connector (7) to the internal slip rings on the upper right corner of the clockspring case.

Within the plastic case and wound around the rotor spool is a long ribbon-like tape that consists of several thin copper wire leads sandwiched between two thin plastic membranes. The outer end of the tape terminates at the connector receptacles that face the instrument panel, while the inner end of the tape terminates at the driver airbag squib pigtail wires and connector receptacle on the hub of the clockspring rotor that face the steering wheel.

The clockspring cannot be repaired. If damaged, ineffective or if the driver airbag has been deployed, the clockspring must be replaced.

STANDARD PROCEDURE - CLOCKSPRING CENTERING

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 and the SAS integral to the clockspring to the movable steering components so that the tape can operate within its designed travel limits and the SAS can accurately monitor and communicate steering wheel inputs. However, if the clockspring is removed from the steering column or if the steering shaft is disconnected from the steering gear, the clockspring spool and the SAS can change position relative to the movable steering components and relative to each other. The clockspring must be replaced if proper centering has been compromised or the tape may be damaged and Diagnostic Trouble Codes (DTC) or faults may be set within the SAS.

Service replacement clocksprings are shipped pre-centered and with a plastic locking pin installed. This locking pin should not be removed until the clockspring has been installed on the steering column. If the locking pin is removed before the clockspring is installed on a steering column, the clockspring must be replaced with a new unit. Proper clockspring installation must also be confirmed by viewing the SAS Menu Item, Data Display function using a diagnostic scan tool.

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 microprocessor in the Occupant Restraint Controller (ORC).

The ORC microprocessor continuously monitors all of the passive restraint system 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 shared 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 or communication between other modules and devices that provide some features of the Supplemental Restraint System (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 microprocessor in the Occupant Restraint Controller (ORC).

The ORC microprocessor continuously monitors all of the passive restraint system 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 shared left and right sensor plus and minus circuits from the ORC.
