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 the airbag warning indicator either fails to light, remains lit continuously or flashes, an SRS
fault is present. 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. Go to step 5.
-
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. Go to step 5
-
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. Go to step 4.
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

Each door has a backup power system which
allows the door to function if your vehicle
has no power. The system has a limited
number of operations before the power is
depleted and turns off. When the system
turns off, the door remains open and
unlatched and does not close.
If your vehicle has no power and the backup
power system is turned off, you can close
