Supplemental Restraint System (SRS) Deactivation And Reactivation: Deactivation

WARNING: This page is about a different car, the 2009 Mercury Grand Marquis and 2009 Ford Crown Victoria. However, it is still accessible from the selected car via links, so may be relevant.
WARNING: Always carry or place a live air bag module with the air bag and deployment door/trim cover/tear seam pointed away from the body. Do not set a live air bag module down with the deployment door/trim cover/tear seam face down. Failure to follow these instructions may result in serious personal injury in the event of an accidental deployment.
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 correct Restraints Control Module (RCM) fuse is removed and the ignition switch is ON.
NOTE: The Supplemental Restraint System (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 below the LH side of the instrument panel, remove the cover and the RCM fuse 22 (10A) from the CJB. For additional information, refer to the appropriate SYSTEM WIRING DIAGRAMS article .
  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.

    See 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 & CABLES article.
    7. NOTE: A tool that has a blunt end, such as a 4.0 mm (0.15 in) Allen wrench, is better able to disengage the steering wheel spring clip from the driver air bag module locking pins.
  7. Using a 4 mm (0.15 in) Allen wrench or suitable tool, place 2 marks on the tool as an aid to remove the driver air bag module. One mark should be approximately 35 mm (1.37 in) from the end of the tool with the second mark approximately 45 mm (1.77 in) from the end of the tool.

    NOTE: The steering wheel rear cover has internal guides that assist in directing the tool to the correct location. Allow the steering wheel rear cover to guide the tool, minimal force is needed.
  8. Gently  insert the tool into a steering wheel rear cover upper access hole until the end of the tool comes into contact with an obstruction. The 45 mm (1.77 in) mark on the tool should be even or close to even with the steering wheel rear cover. If the 45 mm (1.77 in) mark on the tool is not even or close to even with the steering wheel rear cover, remove the tool from the steering wheel and carry out the step once again to correctly position the tool.
    • If the 45 mm (1.77 in) mark on the tool goes into the steering wheel rear cover, the tool was directed past the steering wheel spring clip. Use a tool of a slightly larger diameter or, using the internal guides of the steering wheel rear cover, insert the tool to the 45 mm (1.77 in) mark and proceed to the next step.

    NOTE: The steering wheel is removed for clarity. The upper corner of the steering wheel rear cover is cut away to show the internal guides and the steering wheel spring clip.
  9. With the tool correctly positioned, remove the tool approximately 2-3 mm (0.07-0.11 in) from the access hole then gently push the tool forward (toward front of vehicle). This puts the tool in the best position to disengage the steering wheel spring clip from the driver air bag module locking pin.

    GF0013424Courtesy of FORD MOTOR CO.
    NOTE: Make sure to disengage the steering wheel spring clip from the driver air bag module locking pin before gently pulling the corresponding corner of the driver air bag module. No or very little force is needed to separate the corresponding corner of the driver air bag module from the steering wheel once the spring clip is disengaged from the locking pin.
    NOTE: When the steering wheel spring clip is disengaged from the first locking pin, the corresponding corner of the driver air bag module will only separate 2-4 mm (0.07-0.15 in) from the steering wheel. The driver air bag module will separate more noticeably as subsequent locking pins are disengaged.
  10. Push the tool deeper into the access hole (approximately 4-8 mm [0.15-0.31 in]) with enough force to disengage the steering wheel spring clip from the driver air bag module locking pin. The corresponding corner of the driver air bag module should pop up once the spring clip is disengaged from the locking pin. Gently  pull the corresponding corner of the driver air bag module to make sure the locking pin does not reengage the spring clip. Remove the tool from the access hole. Discontinue pulling on the corresponding corner of the driver air bag module.
    • If the corresponding corner of the driver air bag module does not easily separate from the steering wheel, the spring clip is not disengaged from the locking pin. Repeat the necessary steps to correctly position the tool and disengage the spring clip from the locking pin.
