Scheme 3

1. Except when doing electrical inspections, always turn the ignition switch OFF, ground the SCS line with the HDS to take the PCM out of active status, disconnect the negative cable from the battery, then wait for 3 minutes before starting work. NOTE: The SRS memory is not cleared even if the ignition switch is turned OFF or the battery cables are disconnected from the battery.
2. Use replacement parts which are manufactured to the same standards and quality as the original parts. Do not install used SRS parts. Use only new parts when making SRS repairs.
3. Carefully inspect any SRS part before you install it. Do not install any part that shows signs of being dropped or improperly handled, such as dents, cracks or deformation.
4. Before removing any of the SRS parts (including the disconnection of the connectors), always disconnect the SRS connector.
5. Use only a digital multimeter to check the system. If it is not a Honda multimeter, make sure its output is 10 mA (0.01 A) or less when switched to the lowest value in the ohmmeter range. A tester with a higher output could cause accidental deployment and possible injury.
6. Do not put objects on the front passenger's airbag.
7. The original audio system and the navigation system have a coded theft protection circuit. Be sure to get the client's anti-theft codes before disconnecting the negative cable from the battery.
8. Before returning the vehicle to the client, enter the anti-theft codes for the audio system and the navigation system.
9. If you disconnect the battery cable, the power tilt and telescopic steering wheel system needs to be reset when you reconnect the battery cable. Do the Steering Column Position Memorization (see «STEERING COLUMN POSITION MEMORIZATION»(/acura/rl/ii-2004-2008/remont/manual-power-steering/#power-steering-system-electronic-power-steering-system__steering-column-position-memorization) ).

DTC (Diagnostic Trouble Codes)

The self-diagnostic function of the SRS system allows it to locate the causes of system problems and then store this information in memory. For easier troubleshooting, this data can be retrieved via a data link circuit.

1. When you turn the ignition switch ON (II), the SRS indicator comes on. If it goes off after 6 seconds, the system is normal, and is not currently detecting any abnormality.
2. If there is an abnormality, the system locates and defines the problem, stores this information in memory, and turns the SRS indicator on. The data remains in memory even when the ignition switch is turned off or if the battery is disconnected.
3. The data is stored in memory as a diagnostic trouble code (DTC).
4. DTCs are either latching or resetting depending on the malfunction. With resetting DTCs, the SRS indicator goes off the next time the ignition switch is turned ON and the system is normal, but the DTC is still stored. With latching DTCs, the SRS indicator does not turn OFF until the malfunction is repaired and the DTC is cleared.
5. When you connect the HDS to the data link connector (DLC), you can retrieve a more detailed DTC in the Honda Systems "SRS" menu.
6. After reading and recording the DTC, proceed with the troubleshooting procedure for that code.

Precautions

1. Use only a digital multimeter to check the system. If it's not a Honda multimeter, make sure its output is 10 mA (0.01 A) or less when switched to the smallest value in the ohmmeter range. A tester with a higher output could damage the airbag circuit or cause accidental airbag deployment and possible injury.
2. Whenever the ignition switch is ON (II), or has been turned OFF for less than 3 minutes, be careful not to bump the SRS unit; the airbags could accidentally deploy and cause damage or injuries.
3. Before you remove the dashboard wire harness A or the right side wire harness, disconnect the driver's airbag connector, the front passenger's airbag connector, both side airbag connectors, both side curtain airbag connectors, and both seat belt tensioner connectors.
4. Make sure the battery is sufficiently fully charged. If the battery is dead or low, measured values may not be correct.
5. Do not touch a tester probe to the terminals in the SRS unit or harness connectors, and do not connect the SRS unit terminals or the sensor terminals with a jumper wire. Use only the backprobe set and the multimeter. Backprobe spring-loaded lock type connectors correctly.

SYMPTOM TROUBLESHOOTING INDEX

Airbags

The SRS is a safety device which, when used with the seat belt, is designed to help protect the driver and front passenger in a frontal impact exceeding a certain set limit. The system consists of the SRS unit, including safing sensor and impact sensor (A), the cable reel (B), the driver's airbag (C), the front passenger's airbag (D), side airbags (E), side curtain airbags (L), seat belt tensioners (I), front impact sensors (J), side impact sensors (first) (F), and side impact sensors (second) (K).

Since the driver's and front passenger's airbags use the same sensors, both normally inflate at the same time. However, it is possible for only one airbag to inflate. This can occur when the severity of a collision is at the margin, or threshold, that the SRS unit determines whether or not the airbags will deploy. In such cases, the seat belt will provide sufficient protection, and the supplemental protection offered by the airbag would be minimal.

Scheme 39

Front Passenger's Weight Sensors

The front passenger's weight sensor unit (M) is under the front passenger's seat along with the front passenger's weight sensors (N). The weight sensors detect the weight on the seat, and send the information to the front passenger's weight sensor unit. If the total weight is about 65 lbs (30 kg) or less, the front passenger's weight sensor unit sends a signal to the SRS unit to prevent the passenger's airbag from deploying. When the passenger's airbag is disabled, the passenger airbag cutoff indicator on the center panel comes on to alert the driver that the front passenger's airbag will not deploy in a front-end collision.

Driver's Seat Position Sensor

The driver's seat position sensor (0) is under the driver's seat on the left side. When the driver's seat is moved to its full forward position, the deployment of the driver's airbag is moderated to decrease its force of impact during a front-end collision.

Rear Safing Sensor

The rear safing sensor (P) is located under the middle of the rear seat. The rear safing sensor performs the same basic function as the safing sensor in the SRS unit. It measures sideways G force, such as the force the vehicle would receive in a side collision in the rear, and sends that information to the SRS unit. The SRS unit uses that information, and the information from the second side impact sensors to determine the side that is impacted and the force. If the threshold is met, the SRS unit deploys the side airbag, the side curtain airbag and the seat belt tensioner on that side.

Side Airbags

The side airbags (E) are in each front seat-back. They help protect the upper torso of the driver or front seat passenger during a moderate to severe side impact. Side impact sensors (first) (F) in each door sill, side impact sensors (second) (K) in each rear door sill, rear safing sensor under the rear seat (P), and the SRS unit safing sensor detect such an impact and instantly inflate the driver's or the passenger's side airbag. Only one side airbag will deploy during a side impact. If the impact is on the passenger's side, the passenger's side airbag will deploy even if there is no passenger.

Side Curtain Airbags

The side curtain airbags (L) are in each side of the roof. They help protect the head of the driver, front passenger, and passengers in the rear outer seats during a moderate to severe side impact. Side impact sensors (first) (F) in each front door sill, side impact sensors (second) (K) in each rear door sill, rear safing sensor (P) under the rear seat, and the SRS unit detect such an impact and instantly inflate the driver's or the passenger's side curtain airbag. A side impact causes the side curtain airbag and the side airbag on the impacted side to deploy at the same time.

Seat Belt Tensioners

The seat belt tensioners are linked with the SRS airbags to further increase the effectiveness of the seat belt. In a front-end collision, the tensioners instantly retract the belt firmly to secure the driver and front passenger in their seats.

OPDS

The side airbag system also includes an occupant position detection system (OPDS). This system consists of sensors (G) and a OPDS unit (H) in the front passenger's seat-back. The OPDS unit sends occupant height and position data to the SRS unit. If the OPDS unit determines that the front passenger is of small stature (for example, a child) or the front passenger is leaning into the side airbag deployment path, the SRS unit will automatically disable the passenger's side airbag. The SRS unit will also disable the airbag when the OPDS detects certain objects on the seat. When the side airbag is disabled, the side airbag cutoff indicator on the instrument panel alerts the driver that the passenger's side airbag will not deploy in a side impact. When the object is removed, or the passenger sits upright, the side airbag cutoff indicator will go off after a few seconds, alerting the driver that the passenger's side airbag will deploy in a side impact.

Side Airbag Cutoff Indicator/OPDS Operation

The indicator comes on if the front passenger's seat is occupied by a small adult or child who is leaning into the deployment path, or an object (grocery bag, briefcase, purse, etc.) is in the seat. This indicates the passenger's side airbag is off and will not deploy; there is no problem with the side airbag. If the passenger sits upright or moves to another seat, or you remove the object from the seat, the light should go off. There will be some delay between the occupant's repositioning, and when the indicator will turn on or off.

Passenger Airbag Cutoff Indicator

The indicator comes on if the weight of the front passenger is about 65 lbs or less. This indicates the passenger's front airbag is off and will not deploy. The front airbag is shut off to reduce the chance of airbag-caused injuries.

SRS Operation

The main circuit in the SRS unit senses and judges the force of impact and, if necessary, ignites the inflator charges. If battery voltage is too low or power is disconnected due to the impact, the voltage regulator and the back-up power circuit will keep voltage at a constant level.

For the SRS to operate

Seat Belt Tensioners

1. A front impact sensor or side impact sensor must activate and send electric signals to the microprocessor.
2. The microprocessor must compute the signals and send them to the tensioners.
3. The charges must ignite and deploy the tensioners.

Driver's and Front Passenger's Airbag(s)

1. A front impact sensor must activate and send electric signals to the microprocessor.
2. The microprocessor must compute the signals and send them to the airbag inflator(s).
3. The inflators that receives signals must ignite and deploy the airbags.

Side Airbag(s)

1. A side impact sensor must activate and send electric signals to the microprocessor.
2. The microprocessor must compute the signals and send them to the side airbag inflator(s). However, the microprocessor cuts off the signals to the front passenger's side airbag if the OPDS unit determines if the front passenger's seat is occupied by a small adult or a child who is leaning into the deployment path, or if an object (grocery bag, briefcase, purse, etc.) is in the deployment path of the side airbag.
3. The inflator that receives the signal must ignite and deploy the side airbag.

Side Curtain Airbag(s)

1. Side impact sensors must activate and send electrical signals to the microprocessor.
2. The microprocessor must compute the signals and send them to the side curtain airbag and side airbag inflator(s).
3. The inflator that receives the signals must ignite and deploy the side curtain airbag and side airbag at the same time.

Scheme 40

Self-diagnosis System

A self-diagnosis circuit is built into the SRS unit; when the ignition switch is turned ON (II), the SRS indicator comes on and goes off after about 6 seconds if the system is operating normally.

If the indicator does not come on, or does not go off after 6 seconds, or if it comes on while driving, it indicates an abnormality in the system. The system must be inspected and repaired as soon as possible.

For better serviceability, the SRS unit memory stores a DTC that relates to the cause of the malfunction, and the unit is connected to the data link connector (DLC). This information can be read with the HDS when it is connected to the DLC (16P) (see GENERAL TROUBLESHOOTING INFORMATION ).

Note. Before you disconnect the negative cable from the battery for troubleshooting, make sure you have the anti-theft codes for the audio system and the navigation system.

E-pretensioner ('06-08 Models)

When at a risk of a collision, the e-pretensioner system, working with the collision mitigation braking system (CMBS), retracts the driver's and front passenger's seat belt several times slightly to provide a tactile warming to the driver. And when a collision is imminent, the e-pretensioner system retracts the seat belt tightly to help reduce injury from the impact. The e-pretensioner system also works when the driver brakes hard and the brake assist system is turned on.

CMBS and E-pretensioner Operation ('06-08 Models)

Approaching a vehicle ahead: When driving, the millimeter wave radar detects a vehicle ahead, and the system provides audible and visual warnings if it detects a risk of collision.

Scheme 41

Closing on a vehicle ahead: The system applies light braking, and increases seat belt tension slightly to provide a tactile warning to the driver. The front passenger does not feel the tactile warning.

Scheme 42

Collision unavoidable: The system activates strong braking, and securely tightens both the driver's and front passenger's seat belts to help reduce injury caused by the impact.

Scheme 43

The mechanical portion of the e-pretensioner consists of the motor and the gear sections. When the collision mitigation brake or the brake assist system signals are input, the motor in the retractor section is driven to rewind or retract. If the system judges that the driving situation is safe, the tension on the seat belts is released. The e-pretensioners used in conjunction with the conventional tensioners.

Scheme 44

E-pretensioner Unit ('06-08 Models)

The e-pretensioner unit operates the motor-driving controls based on F-CAN data it receives from the adaptive cruise control unit, VSA modulator-control unit, and the PCM. Also the e-pretensioner unit receives seat belt buckle switch signals from the SRS unit by an interactive communication function. The e-pretensioner unit has a self-diagnostic function, and if it detects a malfunction, it sends its information to the SRS unit. The SRS indicator is then turned on by the SRS unit.

Airbag and Tensioner Disposal

Special Tools Required

Deployment tool 07HAZ-SG00500

Before scrapping any airbags, side airbags, side curtain airbags, or seat belt tensioners (including those in a whole vehicle to be scrapped), the part(s) must be deployed. If the vehicle is still within the warranty period, the Acura District Parts and Service Manager must give approval and/or special instruction before deploying the part(s). Only after the part(s) have been deployed (as the result of vehicle collision, for example), can they be scrapped. If the parts appear intact (not deployed), treat them with extreme caution. Follow this procedure.

Deploying Airbags in the vehicle

If an SRS equipped vehicle is to be entirely scrapped, its airbags, side airbags, side curtain airbags, and seat belt tensioners should be deployed while still in the vehicle. These parts should not be considered as salvageable parts and should never be installed in another vehicle.

Scheme 397

1. Turn the ignition switch OFF, then disconnect the negative cable from the battery, then wait for 3 minutes before starting work.
2. Confirm that each airbag, side airbag, side curtain airbags, or seat belt tensioner is securely mounted.
3. Confirm that the special tool is functioning properly by following the check procedure on the tool label. Driver's Airbag
4. Remove the access panel (A) from the steering wheel, then disconnect the driver's airbag 4P connector (B) from the cable reel. Front Passenger's Airbag
5. Remove the glove box, then disconnect the front passenger's airbag 4P connector (A) from dashboard wire harness A. Side Airbag
6. Disconnect the side airbag 2P connector (A) from the floor wire harness. Side curtain airbag
7. Disconnect the left or right side wire harness 2P connector (A) from the side curtain airbag. Seat belt tensioner
8. Disconnect the floor wire harness 4P connector (A) from the seat belt tensioner. Pull the seat belt out all the way and cut it.
9. Cut off each connector, strip the ends of the wires, and connect the deployment tool alligator clips (A) to the wires. Place the deployment tool at least 30 feet (10 meters) away from the vehicle. NOTE: The driver's and front passenger's airbags have dual inflators. Twist each pair of unlike colored wires together, and clip an alligator clip to each pair.
10. Connect a 12 volt battery to the tool. If the green light on the tool comes on, the igniter circuit is defective and cannot deploy the component. Go to «DISPOSAL OF DAMAGED COMPONENTS»(/acura/rl/ii-2004-2008/remont/airbag/#srs-supplemental-restraint-system__disposal-of-damaged-components) . If the red light on the tool comes on, the component is ready to be deployed.
11. Push the tool's deployment switch. The airbags and tensioners should deploy (deployment is both highly audible and visible: a loud noise and rapid inflation of the bag, followed by slow deflation). If the components deploy and the green light on the tool comes on, continue with this procedure. If a component does not deploy, and the green light comes ON, its igniter is defective. Go to «DISPOSAL OF DAMAGED COMPONENTS»(/acura/rl/ii-2004-2008/remont/airbag/#srs-supplemental-restraint-system__disposal-of-damaged-components) . During deployment the airbags can become hot enough to burn you. Wait for 30 minutes after deployment before touching the airbags.
12. Dispose of the complete airbag. No part of it can be reused. Place it in a sturdy plastic bag (A), and seal it securely. Dispose of the deployed airbag according to your local regulations.

Deploying Components Out of the Vehicle

If an intact airbag or tensioner has been removed from a scrapped vehicle, or has been found defective or damaged during transit, storage, or service, it should be deployed as follows

Scheme 398

1. Confirm that the deployment tool is functioning properly by following the check procedure Deploying Airbags in the Vehicle on the tool label.
2. Position the airbag face up, outdoors, on flat ground, at least 30 feet (10 meters) from any obstacles or people.
3. Follow steps 9 through 12 of the in-vehicle deployment procedure. NOTE: The driver's and front passenger's airbags have dual inflators. Twist each pair of unlike colored wires together, and clip an alligator clip to each pair.

Disposal of Damaged Components

1. If installed in a vehicle, follow the removal procedure for the driver's airbag (see «DRIVER'S AIRBAG REPLACEMENT»(/acura/rl/ii-2004-2008/remont/airbag/#srs-supplemental-restraint-system) ), front passenger's airbag (see «FRONT PASSENGER'S AIRBAG REPLACEMENT»(/acura/rl/ii-2004-2008/remont/airbag/#srs-supplemental-restraint-system) ), side airbag (see «SIDE AIRBAG REPLACEMENT»(/acura/rl/ii-2004-2008/remont/airbag/#srs-supplemental-restraint-system) ), side curtain airbag (see «SIDE CURTAIN AIRBAG REPLACEMENT»(/acura/rl/ii-2004-2008/remont/airbag/#srs-supplemental-restraint-system) ), and seat belt tensioner (see «FRONT SEAT BELT REPLACEMENT»(/acura/rl/ii-2004-2008/remont/restraints-control-systems/#seat-belts__front-seat-belt-replacement) ).
2. In all cases, make a short circuit by cutting, stripping, and twisting together the two inflator wires. NOTE: The driver's and front passenger's airbags have dual inflators. The like color wires go to the individual inflators.
3. Package the component in exactly the same packaging that the new replacement part came in.
4. Mark the outside of the box "DAMAGED AIRBAG NOT DEPLOYED," "DAMAGED SIDE AIRBAG NOT DEPLOYED," "DAMAGED SIDE CURTAIN AIRBAG NOT DEPLOYED," "DAMAGED SEAT BELT TENSIONER NOT DEPLOYED" so it does not get confused with your parts stock.
5. Contact your Acura District Parts and Service Manager for how and where to return it for disposal.

Deployment Tool Check

1. Connect the yellow clips to both the switch protector handles on the tool.
2. Push the operation switch: The green light should come on, indicating that the tool is operating properly and is ready for use. If the red light stays on, the tool is faulty, and another one must be used for the procedure.
