Restraints Control Module (RCM): Installation

1.

To install, reverse the removal procedure.

2.

Repower the SRS.
Do not prove out the SRS at this time. Refer to Supplemental Restraint System (SRS) Depowering and Repowering - With Intelligent Access (IA) or Refer to Supplemental Restraint System (SRS) Depowering and Repowering - Without Intelligent Access (IA) .

3.

PMI is required when installing a new RCM. Refer to the scan tool instructions to carry out PMI.

4.

Prove out the SRS : Turn the ignition from ON to OFF. Wait 10 seconds, then turn the ignition back to ON and monitor the air bag warning indicator with the air bag modules installed. The air bag warning indicator illuminates continuously for approximately 6 seconds and then turns off. If a SRS fault is present, the air bag warning indicator will:
- fail to light.
- remain lit continuously.
- flash.
- The flashing might not occur until approximately 30 seconds after the ignition has been turned from OFF to ON. This is the time required for the RCM to complete the testing of the SRS. If the air bag warning indicator is inoperative and a SRS fault exists, a chime sounds in a pattern of 5 sets of 5 beeps. If this occurs, diagnose and repair the air bag warning indicator and any SRS faults.

5.

Clear the CMDTCs from the RCM and OCSM using the scan tool.
