Removal and Installation

WARNING: To reduce the risk of personal injury, do not use any memory saver devices.

CAUTION: 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 service kit is installed. A scan tool is used to trigger the active command to carry out the OCS system reset.

NOTE:
- If a seat equipped with a supplemental restraint system (SRS) component is being serviced, the supplemental restraint system (SRS) must be depowered.
- The air bag warning lamp illuminates when the restraints control module (RCM) fuse is removed and the ignition switch is ON. This is normal operation and does not indicate a supplemental restraint system (SRS) fault.
- The SRS must be fully operational and free of faults before releasing the vehicle to the customer.

All seats
1. Position the seat to access all the seat track-to-floor pan bolts and the safety belt anchor.
2. Depower the SRS.
3. Remove the front seat.
4. Remove the seat track.
5. Release the cushion trim cover J-clips on the sides of the seat to access the roll pins.
6. Drive out the 2 large roll pins toward the front of the seat cushion pan.
7. Drive out the 2 small roll pins toward the rear of the seat cushion pan.

Power seat recliner
8. Disconnect the power seat backrest adjuster electrical connector.
9. Remove the 3 power seat backrest adjuster bolts.

All seats
10. Remove the manual/power seat backrest adjuster.
11. To install, reverse the removal procedure.
12. Install the seat.
13. Repower the SRS. Do not prove out the SRS at this time.

Passenger seat

14. WARNING: Do not separate the OCS system components.

CAUTION:
- It is necessary to carry out the OCS system reset when a front passenger seat cushion is disassembled, a new trim cover is installed or an OCS service kit is installed. A scan tool is used to trigger the active command to carry out the OCS system reset.
- Make sure the seat is completely assembled before carrying out the OCS system reset.
- The following precautions must be taken before carrying out the OCS system reset.

- Make sure the OCS system components are connected and no faults are present.
- Make sure the OCS system is not at a temperature below 0 °C (32°F) or above 45°C (113°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, 0°C to 45°C (32°F to 113°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 carrying out the OCS system reset process.

NOTE:
- For best results, the OCS system should be at or near room temperature, 10°C to 29°C (50°F to 85°F).
- If the first attempt to carry out the OCS system reset is unsuccessful, a second attempt must be made.

Carry out the OCS system reset active command using the scan tool.
- With the front passenger seat empty, use a scan tool to trigger the active command.

15. NOTE: The ignition switch must be cycled after the OCS system reset.

Cycle the ignition switch from ON to OFF.

All seats
16. Prove out the supplemental restraint system (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 indicator with the air bag modules installed. The air bag indicator will light continuously for approximately 6 seconds and then turn off. If an air bag supplemental restraint system (SRS) fault is present, the air bag 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 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 indicator and any SRS fault discovered must be diagnosed and repaired.

Clear all continuous DTCs from the restraints control module using a scan tool.
