Ford Fiesta: Supplemental Restraint System / Restraints Control Module (RCM). Removal and Installation

Removal

  WARNING: The following procedure prescribes critical repair steps required for correct restraint system operation during a crash. Follow all notes and steps carefully. Failure to follow step instructions may result in incorrect operation of the restraint system and increases the risk of serious personal injury or death in a crash.

NOTE: Carrying out PMI will not enable the 911 assist option that is disabled. The RCM and APIM must be configured correctly to fully support 911 assist functionality.

NOTE: Removal steps in this procedure may contain installation details.

1. NOTE: This step is only necessary when installing a new component.

   NOTE: The PMI process must begin with the current RCM installed. If the current RCM does not respond to the diagnostic scan tool, the tool may prompt for As-Built Data as part of the repair.

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

Installation

1. To install, reverse the removal procedure.
   

1. Repower the SRS . Do not prove out the SRS at this time if installing a new RCM .
   Refer to: Supplemental Restraint System (SRS) Depowering and Repowering (501-20B Supplemental Restraint System, General Procedures).
   

1. 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.
   

1. Prove out the SRS by turning 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 will fail to light, remain lit continuously, or flash.
   

1. 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 airbag 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 airbag warning indicator and any SRS faults.
   

1. Clear all continuous Diagnostic Trouble Codes (DTCs) from the RCM and OCSM using a diagnostic scan tool.
