the process.
-
Make sure a minimum 8-second time period has passed after cycling the ignition switch ON before carrying out the OCS system reset process.
Carry out the Occupant Classification Sensor (OCS) system reset.
7. If the first system reset attempt was unsuccessful, carry out a thorough visual inspection of the following and repair any concerns found.
-
OCS system connector and wiring for damage
-
Pressure sensor hose for kinks and/or damage
-
Seat-related wiring harness and body wiring harness terminals and connectors for damage
8. NOTE: The ignition switch must be cycled after the OCS system reset.
Carry out a second OCS system reset. If the second attempt is unsuccessful, install a new OCS system service kit. For additional information, refer
to Occupant Classification System Service Kit in Restraint Systems.
9. 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 detected, the air bag warning indicator will:
- fail to light.
- remain lit continuously.
- flash.
The flashing might not occur 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 Restraints Control Module (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 and Occupant Classification System Module (OCSM) using a scan tool.
