Removal and Installation

WARNING: Never probe the electrical connectors on air bag, safety canopy or side air curtain modules. Failure to follow this instruction may result in the accidental deployment of these modules, which increases the risk of serious personal injury or death.

WARNING: Never probe the electrical connectors on safety belt buckle/retractor pretensioners or adaptive load limiting retractors. Failure to follow this instruction may result in the accidental deployment of the safety belt pretensioners or adaptive load limiting retractors, which increases the risk of serious personal injury or death.

WARNING: If the seat side air bag cover has been damaged or separated from its mounting, or if the air bag material has been exposed, install a new seat side air bag module. Never try to repair the seat side air bag module. Failure to follow these instructions may result in the seat side air bag deploying incorrectly, which increases the risk of serious personal injury or death in a crash.

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 installed or an OCS system service kit is installed. A scan tool is used to carry out the OCS system reset.

All seats

1. Remove the front seat. For additional information, refer to Seat - Front Seat - Front.

2. Driver power seat, remove the power seat track. For additional information, refer to Seat Track - Front Seat Track - Front.

3. If equipped, pull out and remove the manual recliner handle.

4. Passenger power seat, remove the seat control switch knob.

5. If equipped with 2-way power seat track, remove the rear screw and separate the side shield.

6. If equipped with manual seats, remove the rear screw and side shield.

7. If equipped with 2-way power seat track, remove the seat control switch and side shield.
- Disconnect the seat control switch electrical connector.

8. Release the cushion trim cover J-clip at the back of the trim cover.

9. Release the hook-and-loop strip at the rear of the cushion trim cover.

10. If equipped, disconnect the backrest heated seat element electrical connector.

11. Disconnect and separate the side air bag module electrical connector and wire harness from the cushion pan.

12. Drive out the 2 small roll pins holding the backrest adjuster to the latch/backrest.

13. Remove the 2 cushion-to-lower latch/backrest frame bolts and remove the backrest frame.

14. To install, reverse the removal procedure.

15. Install the seat. For additional information, refer to Seat - Front Seat - Front.

16. Repower the Supplemental Restraint System (SRS). If the passenger seat was 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

17. 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 OCS system reset.

18. 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

19. 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 Air Bag Systems.

20. 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 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 and OCSM using a scan tool.
