Restraints Control Module (RCM): Installation

WARNING: This page is about a different car, the 2018 Ford Focus. However, it is still accessible from the selected car via links, so may be relevant.
WARNING: Incorrect repair techniques or actions can cause an accidental Supplemental Restraint System deployment. Make sure the restraint system is depowered before reconnecting the component. Refer to the Supplemental Restraint System depowering General Procedure in sSupplemental Restraint System (SRS) Depowering and Repowering . Failure to precisely follow depowering instructions could result in serious personal injury from an accidental deployment.
  1. To install, reverse the removal procedure.
  2. If the SRS was depowered, repower the SRS. For a new RCM, do prove out the SRS at this time. Refer to: Supplemental Restraint System (SRS) Depowering and Repowering  .
  3. NOTE: This step is only necessary when installing a new component.

    Using a diagnostic scan tool, complete the PMI process for the RCM following the on-screen instructions.

  4. Using a diagnostic scan tool, carry out the ABS module initialization following the on-screen instruction.
    • Prove out the SRS: Turn the ignition from ON to OFF. Wait 10 seconds, then turn the ignition back to ON and monitor the airbag warning indicator with the airbags installed. The airbag warning indicator illuminates continuously for approximately 6 seconds and then turns off. If a SRS fault is present, the airbag warning indicator either fails to light, remains lit continuously or flashes.

    • The flashing may 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 airbag warning indicator is inoperative and a SRS fault exists, a message will display in the IPC indicating that a SRS fault is present. If this occurs, diagnose and repair the airbag warning indicator and any SRS faults.

  6. Using a scan tool, clear all CMDTC from all modules.
