Supplemental Restraint System (SRS) Deactivation and Reactivation: Deactivation

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: Carry a live air bag module with the air bag and trim cover pointed away from your body. This will reduce the risk of injury in the event of an accidental deployment.
WARNING: Do not set a live air bag module down with the trim cover face down. This will reduce the risk of injury in the event of an accidental deployment.
WARNING: After deployment, the air bag surface can contain deposits of sodium hydroxide, a product of the gas generant combustion that is irritating to the skin. Wash your hands with soap and water afterwards.
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 supplemental restraint system (SRS) component is being serviced, the 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.

    All vehicles 

  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 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).
  7. Disconnect the battery ground cable and wait at least one minute. For additional information, refer to BATTERY, MOUNTING AND CABLES .
  8. 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.

  9. 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.
  10. 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.
  11. 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.

  13. 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.
  14. 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.
  15. 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.

  16. 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.
  17. Working on the same side of the steering wheel, gently  insert the tool into a steering wheel rear cover lower access hole until the end of the tool comes into contact with an obstruction. The 35 mm (1.37 in) mark on the tool should be even or close to even with the steering wheel cover. If the 35 mm (1.37 in) mark on the tool is not even or close to even with the steering wheel cover, remove the tool from the access hole and carry out the step once again to correctly position the tool.
    • If the 35 mm (1.37 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 35 mm (1.37 in) mark and proceed to the next step.
