Supplemental Restraint System (SRS) Depowering and Repowering: Repower

WARNING: This page is about a different car, the 2018 Ford Fiesta. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: The SRS must be fully operational and free of faults before releasing the vehicle to the customer.
  1. Install the BCM fuse 20 (10A).
  2. Connect the battery. Refer to: Battery Disconnect and Connect .
  3. Sit in the driver seat in an upright position. Make sure no objects are between you and the driver airbag, driver lower airbag, side airbag or side air curtain.

    Dimension: 10.0 in (25.4 cm)

  4. Move the driver seat to the rearmost position.
  5. Turn the ignition from OFF to ON.
    • Prove out the SRS as follows: 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 airbag modules 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, "Airbag Malfunction Service Now" displays in the message center. If this occurs, diagnose and repair the airbag warning indicator and any SRS faults.

  7. Using a scan tool, clear all Continuous Memory Diagnostic Trouble Codes (CMDTCs) from all modules.
