Depowering Procedure

WARNING: This page is about a different car, the 2006 Mercury Grand Marquis and 2006 Ford Crown Victoria. However, it is still accessible from the selected car via links, so may be relevant.
WARNING: Always wear safety glasses when repairing an air bag supplemental restraint system (SRS) vehicle and when handling an air bag module. This will reduce the risk of injury in the event of an accidental deployment.
WARNING: Never probe the connectors on the air bag module. Doing so can result in air bag deployment, which can result in personal injury.
WARNING: To reduce the risk of personal injury, do not use any memory saver devices.
NOTE: If a seat equipped with a seat mounted side air bag and/or a safety belt pretensioner (if equipped) system is being serviced, the supplemental restraint system (SRS) must be depowered. 
NOTE: The air bag warning lamp illuminates when the RCM fuse is removed and the ignition switch is ON. This is normal operation and does not indicate a supplemental restraint system (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 central junction box (CJB), located on the LH end of the instrument panel, open the kick panel cover and remove the restraints control module (RCM) fuse 22 (10A) from the CJB. For additional information, refer to the SYSTEM WIRING DIAGRAMS - CROWN VICTORIA or SYSTEM WIRING DIAGRAMS - GRAND MARQUIS .
  4. Turn the ignition ON and visually monitor the air bag indicator for at least 30 seconds. The air bag indicator will remain lit continuously (no flashing) if the correct RCM fuse has been removed. If the air bag indicator does not remain lit continuously, remove the correct RCM fuse before proceeding.
  5. Turn the ignition OFF.
    6. WARNING: To avoid accidental deployment and possible personal injury, the backup power supply must be depleted before repairing or replacing any front or side air bag supplemental restraint system (SRS) components and before servicing, replacing, adjusting or striking components near the front or side air bag sensors, such as doors, instrument panel, console, door latches, strikers, seats and hood latches.
    The front impact severity sensors are located at the top and in front of each side of the radiator core support.
    The side impact sensors (if equipped) are located at or near the base of the B-pillars.
    To deplete the backup power supply energy, disconnect the battery ground cable and wait at least one minute. Be sure to disconnect auxiliary batteries and power supplies (if equipped).
  6. Disconnect the battery ground cable and wait at least one minute. For additional information, refer to BATTERY, MOUNTING AND CABLES .
