Depowering Procedure
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.
-
Never probe the connectors on the air bag module. Doing so can result in air bag deployment, which can result in personal injury.
-
To reduce the risk of personal injury, do not use any memory saver devices.
CAUTION: To avoid potential damage to the restraints control module (RCM), make sure the RCM and bracket assembly is secured to the
floor pan and the SRS is depowered before either disconnecting or reconnecting the RCM electrical connectors.
NOTE:
-
The air bag warning lamp illuminates when the restraints control module (RCM) fuse is removed and the ignition switch is ON. This is normal
operation and does not indicate a supplemental restraint system (SRS) fault.
-
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 below the LH side of the instrument panel, remove the cover and the restraints control module (RCM)
module fuse 20 (10A) from the CJB.
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 switch to 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.
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).
