SUPPLEMENTAL RESTRAINT SYSTEM (SRS) DEPOWERING AND REPOWERING
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.
-
Never probe the electrical connector on a safety canopy module. Doing so can result in safety canopy deployment.
-
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.
-
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.
-
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.
-
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 RH side of the instrument panel, open the kick panel cover and remove the restraints control
module (RCM) fuse 19 (10A) from the CJB.
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 front impact severity sensor is located at the bottom of the hood latch support bracket.
The first row side impact sensors (if equipped) are located in the first row doors, behind the door trim panel.
The second row side impact sensors (if equipped) are located at or near the base of the 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).
Disconnect the battery ground cable and wait at least one minute.
Repowering Procedure
1. 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.
Make sure all restraint system diagnostic tool(s) that may have been installed during the repair have been removed from the vehicle and all SRS
components are connected.
2. Turn the ignition switch from OFF to ON.
3. Install the RCM fuse 19 (10A) to the CJB and close the cover.
4. WARNING: Be sure that nobody is in the vehicle and that there is nothing blocking or set in front of any air bag module when the
battery ground cable is connected.
