DEPOWERING AND REPOWERING
Depowering and Repowering Procedure
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 electrical connectors on air bag, safety canopy or side air curtain modules. Failure to follow this instruction may result in
the accidental deployment of these modules, which increases the risk of serious personal injury or death.
-
To reduce the risk of personal injury, do not use any memory saver devices.
NOTE:
-
If a seat equipped with a SRS component is being serviced, the supplemental restraint system (SRS) must be depowered.
-
The air bag warning indicator 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 smart junction box (SJB), located below the RH side of the instrument panel, remove the RH lower cowl trim panel and remove the
restraints control module (RCM) fuse 8 (10A) from the SJB. For additional information, see the Mazda Truck Wiring Diagrams.
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 OFF.
WARNING: Always deplete the backup power supply before repairing or installing any new front or side air bag supplemental restraint
system (SRS) component and before servicing, removing, installing, adjusting or striking components near the front or side impact
sensors or the restraints control module (RCM). Nearby components include 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 1 minute. Be sure to
disconnect auxiliary batteries and power supplies (if equipped). Failure to follow these instructions may result in serious personal injury
or death in the event of an accidental deployment.
6. Disconnect the battery ground cable and wait at least one minute. See BATTERY DISCONNECT.
Repowering Procedure
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.
7. 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.
8. Turn the ignition switch from OFF to ON.
9. Install the RCM fuse 8 (10A) to the SJB and install the RH lower cowl trim panel.
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.
10. Connect the battery ground cable.
11. Prove out the supplemental restraint system (SRS) as follows:
Turn the ignition key from ON to OFF. Wait 10 seconds, then turn the key back to ON and visually monitor the air bag warning indicator with the
air bag modules installed. The air bag warning indicator lights continuously for approximately 6 seconds then turns off. If an air bag supplemental
restraint system (SRS) fault is present, the air bag warning indicator will either:
-
fail to light.
-
remain lit continuously.
-
flash at a 5Hz rate (RCM not configured).
The air bag warning indicator might light until approximately 30 seconds after the ignition switch has been turned from the OFF to the ON
position. This is the time required for the RCM to complete the testing of the SRS. If the air bag warning indicator is inoperative and a SRS fault
exists, a chime sounds in a pattern of 5 sets of 5 beeps. If this occurs, the air bag warning indicator and any SRS fault discovered must be
diagnosed and repaired.
