Depower
Refer to: Health and Safety Precautions (100-00 General Information, Description and Operation) .
- Determine if a SRS fault is present. Turn the ignition OFF and wait 10 seconds, then turn the ignition ON and monitor the airbag warning indicator. The airbag warning indicator illuminates continuously for approximately 6 seconds and then turns off. Continue to monitor the airbag warning indicator for approximately 30 seconds as this is the time required for the RCM to complete testing of the SRS .
- If a SRS fault is present the airbag warning indicator either fails to light, remains lit continuously or flashes. The flashing may not occur until approximately 30 seconds after the ignition has been turned from OFF to ON. If this occurs, diagnose and repair any SRS faults before proceeding with other repairs.
- If after the ignition has been turned ON for 30 seconds the airbag warning indicator remains unlit with no chime or SRS message displayed in the message center, no SRS fault is present.
- If the airbag warning indicator is inoperative and a SRS fault exists, a chime sounds in a pattern of 5 sets of 5 beeps or a message displays in the message center. If this occurs, diagnose and repair the airbag warning indicator and any SRS faults before proceeding with other repairs.
Turn the ignition OFF and wait one minute before continuing vehicle service.
- Turn the ignition OFF.
- Remove the RCM fuse or if equipped, BECMB fuse(s). Refer to Wiring Diagram Cell 11/Section 700-01 for fuse and relay information.
- For a vehicle equipped with a 3 blade BECMB / GWM fuse, install a 2 blade 10A fuse at the GWM position to allow the scan tool to communicate with the vehicle network.
- Turn the ignition ON.
- Using a diagnostic scan tool, carry out a Network Test. Verify that the RCM and, if equipped, BECMB does not respond to the Network Test. If the RCM or BECMB pass the Network Test, remove the correct RCM or BECMB fuse and repeat the Network Test to verify before proceeding.
- Turn the ignition OFF.
- Disconnect the battery.
Refer to: Battery Disconnect and Connect (414-01 Battery, Mounting and Cables, General Procedures) .
