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: For parts identification and location, refer to Seat — Exploded View, Front in this section.

NOTE: Note all wire harness routing for correct installation.

1. Remove the seat. For additional information, refer to Seat — Front in this section.

2. Remove the clip and recline handle.
   • Access the clip from between the cushion cover and side shield.
   • Use a suitable tool to pull the clip forward and release.

3. Remove and discard the cushion side shield.
   • Remove the screw at the rear of the cushion side shield.
   • Separate the side shield and retainers from the seat.
   • Disconnect the electrical connector. Remove the seat control switch knob and seat control switch.
   • If equipped, disconnect the electrical connector and remove the power lumbar switch.
   • Remove and discard the cushion side shield.
   • Remove any remaining retainers from the seat and discard the one-time use retainer clips.

4. Disconnect the seat position sensor and detach the wire harness retainer.
   • If installing a new seat track, remove the bolt and seat position sensor.

5. Separate the side air bag module electrical connector and wire harness from the seat track bracket.

6. For heated seat or if equipped with power lumbar, release the cushion cover rear J-clip, disconnect the electrical connector(s) and separate the wire harness from the cushion frame.

7. Disconnect the seat track motor electrical connector, and separate the seat wire harness from the seat track motor and seat track bracket.

8. Disconnect the safety belt buckle electrical connector and separate the wire harness from the seat track.

9. Release all cushion cover retainers from the cushion frame.

10. Lift the cushion foam pad for access and remove the 4 nuts and seat track.

11. If a new seat track is being installed, remove the bolt and safety belt buckle.

Installation

All seats

1. If installing a new seat track, install the safety belt buckle and bolt.
   • Tighten to 42 Nm (31 lb-ft).

2. Install the seat track and 4 nuts.
   • Tighten to 36 Nm (27 lb-ft).

3. If installing a new seat track, install the seat position sensor and bolt.
   • Tighten to 6 Nm (53 lb-in).

4. Install the seat wire harness as noted during removal, connect all the electrical connectors and attach all the wire harness retainers.

5. Attach the side air bag module wire harness to the seat track bracket and connect the electrical connector.

6. Attach all the cushion cover retainers to the cushion frame.

7. Install a new cushion side shield.
   • Install the seat control switch, knob and electrical connector.
   • If equipped, install the power lumbar switch and connect the electrical connector.
   • Make sure all the side shield retainers are correctly installed to the side shield.
   • Install the side shield and retainers to the seat.
   • Install the side shield screw.

8. Install the retainer to the recline handle and install to the seat.

9. Install the seat. If a passenger seat has been serviced, do not prove out the Supplemental Restraint System (SRS) at this time. For additional information, refer to Seat — Front in this section.

Passenger seat

10.  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 using System Reset to rezero the seat weight. Failure to follow these instructions may result in incorrect operation of the occupant classification system (OCS) 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 ON before carrying out the OCS system reset.
    Carry out the Occupant Classification Sensor (OCS) system reset.

11. If the first system reset attempt was unsuccessful, make sure no OCSM DTCs are present. If DTC C1941 is the only one retrieved, it will clear upon a successful system reset. All other OCS system DTCs must be diagnosed and repaired before carrying out the OCS system reset.

12. Carry out a thorough 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

13. Carry out a second OCS system reset. If the system reset was unsuccessful, install a new OCS system service kit. For additional information, refer to the Removal and Installation procedures in Section 501-20B .

14. Prove out the Supplemental Restraint System (SRS) as follows:
    Turn the ignition from ON to OFF. Wait 10 seconds, then turn the ignition 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 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 RCM and OCSM CMDTCs .
