Restraints Control Module (RCM) Removal/Installation
RESTRAINTS CONTROL MODULE (RCM) REMOVAL/INSTALLATION
Removal
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 and cause serious personal injury or death.
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.
CAUTION:When installing a new restraints control module (RCM), it is necessary to carry out programmable module installation (PMI). See Module Configuration. Failure to follow these instructions may result in component damage and/or system failure.
NOTE:The air bag warning indicator illuminates when the correct RCM fuse is removed and the ignition is ON.
NOTE:The SRS must be fully operational and free of faults before releasing the vehicle to the customer.
1. If installing a new restraints control module (RCM), carry out the steps necessary to prepare for programmable module installation (PMI). See Module Configuration.
2. Depower the system. See Supplemental Restraint System (SRS) Depowering And Repowering.
3. Remove the 2 front LH floor console screws and position the carpet aside to access the RCM bolts.
4. Remove the lower LH center instrument panel finish panel.
- Remove the pin-type retainer.
- Release the 2 retainer hooks from the instrument panel brace.
5. Disengage the lock tab, press and disconnect the small RCM electrical connector.
6. Disconnect the large RCM electrical connector.
a. Pinch the thumb tab and pivot the connector position assurance lever all the way back until it stops.
b. Pull out and disconnect the RCM electrical connector.
7. Remove the 3 bolts and RCM.
Installation
1. Position the RCM and install the 3 bolts.
- Tighten to 11 Nm {1.1 kgf-m, 97 in-lbf}.
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.
2. Make sure the connector position assurance lever is in the full release position before attempting to connect the connector.
3. Position the large RCM electrical wiring connector into the RCM.
- 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.
- Pivot the connector position assurance lever toward the RCM, drawing the connector in to 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 and push the lock tab in.
6. Position back the carpet on the LH and RH tunnel to its original position.
7. Install the lower LH center instrument panel finish panel.
- Attach the 2 retainer hooks to the instrument panel brace.
- Install the pin-type retainer.
8. Position the carpet into place and install the 2 front LH floor console screws.
9. Repower the system. See Supplemental Restraint System (SRS) Depowering And Repowering.
10. When installing a new RCM, carry out the steps necessary to complete programmable module installation (PMI). See Module Configuration.
11. Prove out the supplemental restraint system (SRS) as follows:
Turn the ignition switch from ON to OFF. Wait 10 seconds, then turn the ignition switch back to ON and visually monitor the air bag indicator with the air bag modules installed. The air bag warning indicator will light continuously for approximately 6 seconds and then turn OFF. If an air bag SRS fault is present, the air bag warning indicator will:
- fail to light.
- remain lit continuously.
- flash at a 5 Hz rate (RCM not configured).
The air bag warning indicator might not light until approximately 30 seconds after the ignition switch has been turned from the OFF to the ON position. This is the time required for the RCM to complete the testing of the SRS. If the air bag indicator is inoperative and a SRS fault exists, a chime will sound in a pattern of 5 sets of 5 beeps. If this occurs, the air bag warning indicator and any SRS fault discovered must be diagnosed and repaired.
Clear all continuous diagnostic trouble codes (DTCs) from the RCM.
