Supplemental Restraint System (SRS) Deactivation and Reactivation: Deactivation

WARNING: This page is about a different car, the 2005 Mercury Mountaineer and 2005 Ford Explorer. 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: The safety belt pretensioner is a pyrotechnic device. Always wear safety glasses when repairing an air bag equipped vehicle and when handling a safety belt buckle pretensioner or safety belt retractor pretensioner. Never probe a pretensioner electrical connector. Doing so could result in pretensioner or air bag deployment and could result in personal injury.
WARNING: Never probe the connectors on the safety canopy module. Doing so can result in safety canopy deployment.
WARNING: The restraint system diagnostic tool is for restraint system service only. Remove from vehicle prior to road use. Failure to remove could result in injury and possible violation of vehicle safety standards.
WARNING: Do not handle, move or change the original horizontal mounting position of the restraints control module (RCM) while the RCM is connected and the ignition switch is ON. Failure to follow these instructions may result in the inadvertent deployment of the safety canopy and risk of 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 restraints control module (RCM) fuse F2.19 (10A) from the CJB. For additional information, refer to SUPPLEMENTAL RESTRAINTS for the Explorer and SUPPLEMENTAL RESTRAINTS for the Mountaineer.
  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 or RCM, such as doors, instrument panel, console, door latches, strikers, seats and hood latches.
    The side impact sensors (if equipped) are located at or near the base of the B-pillars and C-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 1 minute. For additional information, refer to BATTERY, MOUNTING AND CABLES .
  7. Remove the 2 steering wheel back cover plugs (one shown).

  9. Remove the driver air bag module.
    1. Release the 2 retaining tabs. Disconnect the driver air bag module electrical connector.
      • Label the driver air bag module squib number on the driver air bag module electrical connector before disconnecting.
    2. Release the 2 retaining tabs. Disconnect the driver air bag module electrical connector.
      • Label the driver air bag module squib number on the driver air bag module electrical connector before disconnecting.
    3. Disconnect the horn switch electrical connector.
    4. Remove the driver air bag module.

    14. Vehicles without safety canopies 

    CAUTION: Do not deactivate the safety canopy module circuit by removing the safety canopy bridge resistor from the safety canopy electrical connector.
  14. If the safety canopy bridge resistor is removed, an open circuit fault will be generated by the restraints control module (RCM).

    If a restraint system diagnostic tool is installed at the safety canopy electrical connector, a low resistance fault will be generated by the RCM.

    15. Vehicles with safety canopies 

  15. Remove the RH C-pillar trim panel.
    1. Pull out and release the retaining clips.
    2. Pull out and release the retainer.
    3. Lower the door opening weatherstrip, slide the C-pillar trim panel up, releasing the retainers and remove the C-pillar trim panel.
