Removal and Installation
NOTICE: To prevent system failure, it is necessary to carry out the Occupant Classification Sensor (OCS) system reset when a front passenger seat cushion is disassembled, a new trim cover is installed or an OCS system service kit is installed. A scan tool is used to carry out the OCS system reset.
NOTE: The air bag warning indicator illuminates when the correct Restraints Control Module (RCM) fuse is removed and the ignition switch is ON.
NOTE: The Supplemental Restraint System (SRS) must be fully operational and free of faults before releasing the vehicle to the customer.
NOTE: Note all wire harness routing for correct installation.
All seats
1. Remove the front seat. For additional information, refer to Seat - Front Seat - Front.
2. Remove the clip and recline handle.
3. Remove the screw at the rear of the cushion side shield. Pull out on the side of the cushion side shield, release the retaining clips and pin-type retainer and separate the side shield.

6. Separate the side air bag module electrical connector and wire harness from the power seat track bracket.
7. Release the cushion trim cover rear J-clip, disconnect the power lumbar electrical connector and separate it from the cushion frame.
8. Disconnect the power seat track motor electrical connector, separate the main seat electrical connector and wire harness from the power seat track bracket and position the wire harness aside.
9. Disconnect the safety belt buckle switch and separate the pin-type retainer from the seat track.
10. Release all cushion trim cover to cushion frame retainers.
11. Remove the 4 nuts and power seat track.
- Lift the cushion foam pad to access the power seat track nuts.
- To install, tighten to 36 Nm (27 lb-ft).
12. Remove the bolts and safety belt buckle and bracket.
- To install, tighten to 42 Nm (31 lb-ft).
13. To install, reverse the removal procedure.
14. Install the seat. For additional information, refer to Seat - Front Seat - Front.
15. Repower the SRS. If the passenger seat has been serviced, do not prove out the SRS at this time. For additional information, refer to Supplemental Restraint System (SRS) Depowering and Repowering in the General Procedures of Air Bag Systems.
Passenger seat
16. WARNING: Make sure the front passenger seat repair is complete, the seat and all attached components (head restraint, seat side shield, etc.) are correctly assembled, and the seat is correctly installed to the vehicle before carrying out the System Reset. Failure to follow these instructions may result in incorrect operation of the occupant classification sensor (OCS) system and increases the risk of serious personal injury or death in a crash.
WARNING: Install a new occupant classification sensor (OCS) system service kit as a complete assembly. Never install only part of the kit components. Failure to follow this instruction may result in incorrect operation of the OCS system and increases the risk of serious personal injury or death in a crash.
NOTICE: To prevent system failure, the following precautions must be taken before carrying out the Occupant Classification Sensor (OCS) system reset:
- Make sure the voltage to the Occupant Classification System Module (OCSM) is above 8 volts and less than 18 volts.
- Make sure the OCS system is not at a temperature below 6°C (42°F) or above 36°C (97°F) when initiating the OCS system reset process. If the vehicle has been exposed to extreme cold or hot temperatures, the vehicle must be exposed and kept at a temperature within the limits, 6°C to 36°C (42°F to 97°F) for a minimum of 30 minutes.
- Make sure nothing is present on the passenger seat before carrying out the OCS system reset and nothing is placed on the seat during the process.
- Make sure a minimum 8-second time period has passed after cycling the ignition switch ON before the carrying out the OCS system reset process.
Carry out the Occupant Classification Sensor (OCS) system reset.
17. 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
18. 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 Sensor in Air Bag Systems.

19. 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 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.
