Air Bag Control Module: Service and Repair




Restraints Control Module (RCM)









Removal

WARNING: If a vehicle has been in a crash, inspect the restraints control module (RCM) and the impact sensor (if equipped) mounting areas for deformation. If damaged, restore the mounting areas to the original production configuration. A new RCM and sensors must be installed whether or not the air bags have deployed. Failure to follow these instructions may result in serious personal injury or death in a crash.

WARNING: Do not handle, move or change the original horizontal mounting position of the restraints control module (RCM) while the RCM is connected and the ignition switch is ON. Failure to follow this instruction may result in the accidental deployment of the Safety Canopy(R) and cause serious personal injury or death.

NOTICE: When installing a new Restraints Control Module (RCM), it is necessary to carry out Programmable Module Installation (PMI) Programming and Relearning. System failure may occur if PMI is not performed. For additional information, refer to Information Bus.

NOTE: When installing a new Restraints Control Module (RCM) always make sure the correct RCM is being installed. If an incorrect RCM is installed, DTCs will be set.

NOTE: The air bag warning indicator illuminates when the correct RCM fuse is removed and the ignition is ON.

NOTE: The Supplemental Restraint System (SRS) must be fully operational and free of faults before releasing the vehicle to the customer.

NOTE: Carrying out Programmable Module Installation (PMI) will not enable the 911 assist option that is disabled. The RCM and Accessory Protocol Interface Module (APIM) must be configured correctly to fully support 911 assist functionality.

1. When installing a new RCM, carry out the appropriate steps necessary for the Programmable Module Installation (PMI) procedure. Programming and Relearning

2. Depower the SRS. For additional information, refer to Supplemental Restraint System (SRS) Depowering and Repowering Supplemental Restraint System (SRS) Depowering and Repowering.

3. Remove the floor console.

4. Disconnect the selector lever cable from the ball stud located on the shifter and remove the cable from the retaining clips.





5. Remove the 4 bolts (2 each side) from the inner floor console support.

6. Remove the bolts from the inner floor console support-to-instrument panel.

7. Disconnect the electrical connectors from the front inner floor console support.

8. Remove the floor console.

9. Press to release the locking tab and disconnect the small RCM electrical connector.





10. Disconnect the large RCM electrical connector.

1. Pinch the thumb tab and pivot the connector position assurance lever all the way back until it stops.

2. Pull out and disconnect the RCM electrical connector.





11. Remove the 3 bolts and RCM.

Installation

1. WARNING: Always tighten the fasteners of the restraints control module (RCM) and impact sensor (if equipped) to the specified torque. Failure to do so may result in incorrect restraint system operation, which increases the risk of personal injury or death in a crash.

Install the RCM and the 3 bolts.
- Tighten to 12 Nm (106 lb-in).

2. Make sure the large RCM connector position assurance lever is in the full release position before attempting to connect the connector.





3. NOTICE: Placing the large Restraints Control Module (RCM) electrical wiring connector into the RCM on an angle, may cause bad electrical connections and damaged components.

Position the large RCM electrical connector into the RCM.

- NOTICE: Do not push the connector to the point where the lever pivots and seats itself. Light pressure is needed to get the connector into position on the Restraints Control Module (RCM), before using the lever to fully seat the connector. Failure to follow these instructions may cause component or connector damage.

With the large RCM electrical connector uniformly aligned to the RCM, lightly push in until a subtle audible click is heard and slight resistance is felt.





4. Connect the large RCM electrical connector.
- Using the connector position assurance lever, pivot it toward the RCM drawing the connector into the RCM.
- Make sure the thumb tab is engaged to the retainer on the RCM and locked in place.





5. Connect the small RCM electrical connector.

6. Install the inner floor console support.

7. Install the 4 bolts (2 each side) to the inner floor console support.
- Tighten to 12 Nm (106 lb-in).

8. Install the screws to the inner floor console support bracket-to-floor instrument panel.
- Tighten to 12 Nm (106 lb-in).

9. Install the selector lever cable in the selector lever housing.

10. NOTE: When installing the selector lever cable, make sure that the selector lever cable locking tabs are locked in place and the cable end is snapped onto the ball stud. Press the selector lever cable into the bracket and listen for the cable to click in place. Pull back on the selector lever cable to make sure that it is locked into the bracket. Also make sure that the selector lever cable end is correctly installed onto the ball stud. Pull back on the selector lever cable end to make sure that the cable end is correctly installed.

Connect the selector lever cable end to the floor shifter.

11. Attach the electrical connectors to the front inner floor console support bracket.

12. Install the floor console.

13. Repower the SRS. For additional information, refer to Supplemental Restraint System (SRS) Depowering and Repowering Supplemental Restraint System (SRS) Depowering and Repowering.

14. If a new RCM was installed, carry out the appropriate steps to complete the Programmable Module Installation (PMI) procedure. Programming and Relearning
