Depowering Procedure
WARNING: This page is about a different car, the 2005 Mercury Montego, 2005 Ford Freestyle, and 2005 Ford Five Hundred. 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:
Never probe the electrical connector on a safety canopy module. Doing so can result in safety canopy deployment.
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 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.
- Turn all vehicle accessories OFF.
- Turn the ignition switch to OFF.
- At the smart junction box (SJB), located below the LH side of the instrument panel, remove the cover and the restraints control module (RCM) fuse F2.21 (7.5A) from the SJB. For additional information, refer to the Wiring Diagram Manual.
- 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.
- Turn the ignition switch to OFF.
- Disconnect the battery ground cable (14301) and wait at least 1 minute. For additional information, refer to BATTERY, MOUNTING AND CABLES .
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 on the radiator support bracket near the front headlamp assemblies.
The first row side impact sensors (if equipped) are located at or near the base of the B -pillars.
The second row side impact sensors (if equipped) are located on the C-pillar.
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).
