Restraints Control Module (RCM): Installation

WARNING: This page is about a different car, the 2005 Lincoln Town Car. However, it is still accessible from the selected car via links, so may be relevant.
    WARNING: The tightening torque of the air bag restraints control module (RCM) retaining bolts is critical for correct system operation.

  2. Connect the small RCM electrical connector.
    1. Install the bolt.
    2. Connect the small RCM electrical connector.
  3. Make sure the connector position assurance lever is all the way back and in the full release position before attempting to connect the connector.

    4. CAUTION: Putting the large RCM electrical connector into the RCM on an angle can cause bad electrical connections and damage components.
    NOTE: The RCM has been removed for clarity.

  4. Position the large RCM electrical connector into the RCM.
      CAUTION: Do not push the connector on to where the lever pivots and seats itself. Light pressure is needed to get the connector into position on the RCM before using the lever to fully seat the connector.
    • 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.
    5. NOTE: The RCM has been removed for clarity.

  5. 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 is locked in place.
  6. Install the insulator on top of the RCM.
  7. Install the ashtray bracket.
    1. Position the ashtray bracket to the instrument panel.
    2. Install the screws.

  10. Repower the SRS. Do not prove out the system at this time  . For additional information, refer to SUPPLEMENTAL RESTRAINT SYSTEM (SRS) DEPOWERING AND REPOWERING .
    11. NOTE: When a new RCM is first installed in the vehicle, module configuration must be carried out. The diagnostic trouble code (DTC) B2477 will be stored in the RCM memory (continuous fault) and will flash lamp fault code (LFC) 54 (or higher priority code if one exists) on the air bag indicator. The DTC B2477 cannot be cleared from memory until RCM configuration has been carried out.
  11. If a new RCM is being installed, configure the RCM. For additional information, refer to MODULE CONFIGURATION .
  12. Prove out the supplemental restraint system (SRS) as follows:

    Turn the ignition key from ON to OFF. Wait 10 seconds, then turn the key back to ON and visually monitor the air bag indicator with the air bag modules installed. The air bag indicator will light continuously for approximately six seconds and then turn off. If an air bag supplemental restraint system (SRS) fault is present, the air bag indicator will either:

    • fail to light.
    • remain lit continuously.
    • flash.

    The flashing might not occur 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 restraints control module (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 five sets of five beeps. If this occurs, the air bag indicator and any SRS fault discovered must be diagnosed and repaired.

    Clear all continuous DTCs from the restraints control module using a diagnostic tool.
