Removal and Installation
WARNING:
- The safety belt pretensioner is a pyrotechnic device. Never probe a pretensioner electrical connector. Doing so could result in pretensioner or air bag deployment and could result in personal injury.
- Never probe the connectors on the air bag module. Doing so can result in air bag deployment, which can result in personal injury.
- To reduce the risk of personal injury, do not use any memory saver devices.
CAUTION: If replacing only the front passenger seat cushion trim cover, the occupant classification sensor must be rezeroed.
NOTE:
- If a seat equipped with a supplemental restraint system (SRS) component is being serviced, the 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.
- Occupant classification sensor (OCS) system components (seat cushion foam pad, bladder with pressure sensor and electronic control unit) are calibrated to each other and are serviced as an assembly. The OCS system components are not to be installed separately. If a new OCS system, OCS system component or seat cushion foam pad are needed, a new OCS system service kit (seat cushion foam pad, bladder with pressure sensor and electronic control unit) must be installed as an assembly.
- To identify between a production OCS system and a service OCS system (OCS service kit) inspect the electronic control unit (ECU) electrical connector. A production OCS system allows the disconnect of the ECU electrical connector. A service OCS system (OCS service kit) has the ECU electrical connector glued to the ECU, it cannot and should not be disconnected or altered.
- The SRS must be fully operational and free of faults before releasing the vehicle to the customer.
Manual seats
1. Depower the SRS.
Power seats
2. Remove the affected seat and depower the SRS.
3. Remove the front seat backrest.
All seats
4. NOTE: Disconnect and release any remaining electrical connectors and pin-type retainers necessary to separate the seat cushion frame from the seat track and riser.
Remove the 4 seat track-to-seat cushion frame bolts and remove the seat cushion.
- To install, tighten to 25 Nm (18 lb-ft).
5. Release the J-clips.
6. Remove the seat cushion hog rings (2 shown), if equipped and remove the seat cushion trim cover.
7. To install, reverse the removal procedure.
Power seats
8. Install the front seat backrest.
9. Install the affected seat and repower the SRS. Do not prove out the SRS at this time.
Manual seats
10. Repower the SRS. Do not prove out the system at this time.
Passenger seats
11. CAUTION:
- There are 3 occupant classification sensor (OCS) system service kits available for this vehicle (base seat, heated seat and climate controlled seat). Always make sure the correct OCS service kit is installed.
- It is necessary to rezero the OCS system when a front passenger seat cushion is disassembled, a new trim cover installed, a seat side shield removed or an OCS service kit is installed. A scan tool is used to trigger the active command to carry out rezeroing of the OCS system.
- Make sure the seat is completely assembled before rezeroing.
- The following precautions must be taken before rezeroing the OCS system:
- 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 rezeroing 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 rezeroing and nothing is placed on the seat during the rezeroing process.
- Make sure a minimum 8 second time period has passed after cycling the ignition switch ON before the rezeroing process.
NOTE:
- For best results in rezeroing, the OCS system should be at or near room temperature, 10°C to 29°C (50°F to 85°F).
- The heater mat on the front passenger seat cushion is not serviceable separately. If a new heater mat is needed on the front passenger seat cushion a new occupant classification sensor (OCS) service kit, equipped with a heater mat, must be installed.
- If the first attempt to rezero the OCS system is unsuccessful, a second attempt must be made.
Rezero the occupant classification sensor.
- With the front passenger seat empty, use a scan tool to trigger the active command and rezero the occupant classification sensor.
12. NOTE: The ignition switch must be cycled after rezeroing the OCS system.
Cycle the ignition switch from ON to OFF.

13. 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.
