Restraints Control Module (RCM): Installation

  1. Install the RCM.
  2. Install the 3 RCM nuts.
    • Tighten to 12 Nm (9 lb-ft).
  3. Connect the small RCM electrical connector.
    4. NOTE: The RCM has been removed for clarity.
  4. On the large RCM electrical connector, place the connector position assurance lever in the full release position.

  6. Connect the large RCM connector.
      NOTE: 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. Damage to the connector or component may occur.
    • With the large RCM electrical connector uniformly aligned to the RCM, lightly push in until a subtle audible click is heard and a slight resistance is felt.
    • 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.

  7. Install the front floor console. For additional information, refer to INSTRUMENT PANEL AND CONSOLE article.
  8. Repower the SRS. Do not prove out the SRS at this time  . For additional information, refer to Supplemental Restraint System (SRS) Depowering and Repowering  in the General Procedures portion of this article.
  9. Carry out the steps necessary to complete PMI. For additional information, refer to MODULE CONFIGURATION article.
  10. Prove out the 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 warning 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 warning 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 DTCs from the RCM and occupant classification system module (OCSM) using a scan tool.
