Depower
WARNING:
Incorrect repair techniques or actions can cause an
accidental Supplemental Restraint System (SRS) deployment. Never
compromise or depart from these instructions. Failure to precisely
follow all instructions could result in serious personal injury from an
accidental deployment.
-
WARNING:
Before beginning any service procedure in this
manual, refer to health and safety warnings in section 100-00 General
Information. Failure to follow this instruction may result in serious
personal injury.
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.
No SRS Fault Present (with ignition ON, airbag warning indicator stays off after prove out)
-
WARNING:
Turn the ignition OFF and wait one minute to
deplete the backup power supply. Ignition must remain OFF until repair
is complete. Failure to follow this instruction may result in serious
personal injury or death in the event of an accidental deployment.
Turn the ignition OFF and wait one minute before continuing vehicle service.
SRS Fault Present
-
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.

blade 10A fuse at the GWM position to allow the scan tool to communicate
with the vehicle network.

-
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.
