Possible Causes

NOTE: Most faults are due to connector and/or wiring concerns. Carry out a thorough inspection and verification before proceeding with the pinpoint test.
NOTE: Only disconnect or reconnect SRS components when instructed to do so within a pinpoint test step. Failure to follow this instruction may result in incorrect diagnosis of the SRS.
NOTE: Always make sure the correct SRS component is being installed. Parts released for other vehicles may not be compatible even if they appear physically similar. Check the part number listed in the Ford parts catalog to make sure the correct component is being installed. If an incorrect SRS component is installed, DTCs may set.
NOTE: The SRS must be fully operational and free of faults before releasing the vehicle to the customer.
  1. L1: RETRIEVE RCM DTCS 
    WARNING: Before beginning any service procedure in this article, refer to Safety Warnings in General Information article. Failure to follow this instruction may result in serious personal injury.
    NOTE: Diagnose all network-related (lost communication) DTCs first.

    Yes No
    This fault cannot be cleared until it is corrected and the DTC is no longer retrieved on-demand during self-test.
    For DTC B00A0:09, B00A0:63 or B00A0:68, RETRIEVE and DIAGNOSE the OCSM DTCs.

    Go to  L5.
  4. L4: VERIFY THE RCM CONFIGURATION 
    NOTE: It is necessary to exit the guided diagnostics to use the IDS to carry out the PMI process.
    • Carry out PMI for the RCM. Manually enter As-Built data. Refer to the diagnostic scan tool instructions when carrying out PMI.
    • Carry out the RCM self-test.
    • Is DTC B00A0:4A retrieved on-demand during self-test? 
    Yes No
    Go to  L5. The fault is corrected.
    Go to  L6.
  5. L5: REPLACE THE RCM
