- Park the vehicle on level ground.
- Make sure the occupant classification sensor (OCS) system is stabilized at a temperature in the range of 5°C to 48°C (41°F to 118°F) and is not exposed to temperatures outside that range.
- Make sure the front passenger seat is empty and dry.
- Make sure the front passenger seat repair is complete and all attached components (head restraint, seat side shield) are correctly installed.
- Make sure nothing is placed in the map pockets (if equipped) of the front passenger seat.
- Make sure nothing is underneath the front passenger seat.
- Make sure no non-factory installed items (seat covers, DVD screens) are on or contacting the front passenger seat. If any non-factory items were installed to the seat, remove the item(s) and communicate to the customer that any alteration/modification to the front passenger seat may affect performance of the OCS system. Refer to the Owner's Literature.
- Make sure the seat is correctly installed in the vehicle.
- Make sure the passenger safety belt buckle is unbuckled.
Make sure the vehicles electrical system voltage is below 18 volts and above 11.5 volts before continuing.
- Position the front passenger seat in the first position.
- Position the seat backrest in the upright position.
- Position the seat in the full forward position of seat track travel.
- Position the seat height to its highest position (power seat only).
- Remove hysteresis from the front passenger seat by firmly hitting the back of the seat head restraint 3 times.
- Turn the ignition to the OFF position.
- Carry out the Zero Seat Weight Test.
- If the system passed, proceed to Step 6 .
- If the system did not pass (DTC B00A0:67 Occupant Classification System: Signal Incorrect After Event), proceed to Step 8. If DTC B00A0:54 is also stored in the OCSM , go to the OCCUPANT CLASSIFICATION SYSTEM MODULE (OCSM) DTC CHART for diagnostic direction of this DTC.
- Position the front passenger seat to the second position.
- Position the seat in the full rearward position of seat track travel.
- Position the seat height to its lowest position (power seat only).
- Carry out the Zero Seat Weight Test.
- If the system passed, repair is complete, proceed to Step 9.
- If the system did not pass (DTC B00A0:67 Occupant Classification System: Signal Incorrect After Event), proceed to Step 8 . If DTC B00A0:54 is also stored in the OCSM , go to the OCCUPANT CLASSIFICATION SYSTEM MODULE (OCSM) DTC CHART for diagnostic direction of this DTC.
- Inspect the following for causes of a unsuccessful Zero Seat Weight Test.
- Make sure the front passenger seat is empty and there is nothing underneath the seat. Remove any items from the seat that were not factory installed and make sure that the seat is correctly installed in the vehicle.
- Make sure the seat wiring harnesses are routed and secured correctly and are not twisted, pinched, pulling down or pushing up on any seat component. Refer to Seat Cushion Wire Harness Routing - Front Passenger Cushion in GENERAL PROCEDURES .
- Make sure the OCS weight sensor bolt protection brackets are correctly installed to the seat track and are not contacting the cushion side shield, wire harness or any other surrounding parts.
- Make sure the seat track and backrest frame are not bent, twisted or damaged.
- Move the seat and backrest to all seating positions. Make sure the seat track does not bind or have any resistance when moved to all seating positions. Make sure that there are no obstructions contacting any seat component when the seat is moved to all seating positions.
- Make sure the seat is assembled correctly and all fasteners are tightened to specifications.
- If a concern was found, repair as necessary, proceed to Step 1.
- If no concern was found, install a new passenger seat track assembly with OCS weight sensor bolts. For additional information, refer to REMOVAL AND INSTALLATION .
- Prove out the SRS
as follows:
Turn the ignition from ON to OFF. Wait 10 seconds, then turn the ignition 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 (RCM not configured).
The air bag warning indicator might not light until approximately 30 seconds after the ignition 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.
Repair any unresolved DTCs.
Clear all continuous DTCs from the RCM and OCSM using a scan tool.
Failure to follow these instructions may result in incorrect operation of the OCS system and increases the risk of serious personal injury or death in a crash.
