Depowering Procedure

WARNING: This page is about a different car, the 2007 Ford Ranger. However, it is still accessible from the selected car via links, so may be relevant.
WARNING: Never probe the electrical connectors on air bag, safety canopy or side air curtain modules. Failure to follow this instruction may result in the accidental deployment of these modules, which increases the risk of serious personal injury or death.
WARNING: To reduce the risk of accidental deployment, do not use any memory saver devices. Failure to follow this instruction may result in serious personal injury or death.
NOTE: The air bag warning indicator illuminates when the restraints control module (RCM) fuse is removed and the ignition switch is ON. This is normal operation and does not indicate an SRS fault.
NOTE: The SRS must be fully operational and free of faults before releasing the vehicle to the customer.
  1. Turn all vehicle accessories OFF.
  2. Turn the ignition switch to OFF.
  3. At the smart junction box (SJB), located below the RH side of the instrument panel, remove the RH lower cowl trim panel and remove the restraints control module (RCM) fuse 8 (10A) from the SJB. For additional information, refer to the Wiring Diagram Manual.
  4. Turn the ignition ON and visually monitor the air bag warning indicator for at least 30 seconds. The air bag warning indicator will remain lit continuously (no flashing) if the correct RCM fuse has been removed. If the air bag warning indicator does not remain lit continuously, remove the correct RCM fuse before proceeding.
  5. Turn the ignition OFF.
    6. WARNING: Always deplete the backup power supply before repairing or installing any new front or side air bag supplemental restraint system (SRS) component and before servicing, removing, installing, adjusting or striking components near the front or side impact sensors or the restraints control module (RCM). Nearby components include doors, instrument panel, console, door latches, strikers, seats and hood latches.

    Refer to DESCRIPTION AND OPERATION  for location of the RCM and impact sensor(s).

    To deplete the backup power supply energy, disconnect the battery ground cable and wait at least 1 minute. Be sure to disconnect auxiliary batteries and power supplies (if equipped).

    Failure to follow these instructions may result in serious personal injury or death in the event of an accidental deployment.

  6. Disconnect the battery ground cable and wait at least one minute. For additional information, refer to BATTERY, MOUNTING AND CABLES article.
