process.
NOTE: If the first attempt to carry out the OCS system reset is unsuccessful, a second attempt must be made. If the second attempt to carry out the
OCS system reset is unsuccessful, a new OCS system service kit must be installed.

28. Prove out the 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 will light continuously for approximately 6 seconds and then turn off. If an air bag SRS
fault is present, the air bag warning indicator will:
-
fail to light.
-
remain lit continuously.
-
flash at a 5Hz rate (RCM not configured).
The air bag warning indicator might not 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 will sound 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.
Clear all continuous DTCs from the RCM using a scan tool.
