DISASSEMBLY
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.
CAUTION: If replacing only the front passenger seat cushion trim cover, the occupant classification sensor must be rezeroed.
NOTE:
- 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 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.
- Repair is made by installing a new part only. If the new part does not correct the condition, install the original part and perform the diagnostic procedure again.
- When installing a new occupant classification sensor (OCS) service kit, refer to Air Bag Systems for the OCS service kit installation procedure.
- Power seat is shown, manual seat is similar.
1. WARNING: To avoid accidental deployment and possible personal injury, the backup power supply must be depleted before repairing or replacing any front or side air bag supplemental restraint system (SRS) components and before servicing, replacing, adjusting or striking components near the front or side air bag sensors or RCM, such as doors, instrument panel, console, door latches, strikers, seats and hood latches.
The front impact severity sensor is located under the hood latch bracket.
The first row side impact sensors (if equipped) are located under the seat, beneath the carpet.
The second row side impact sensors (if equipped) are located at or near the base of the C-pillar.
To deplete the backup power supply energy, disconnect the battery ground cable and wait at least one minute. Be sure to disconnect auxiliary batteries and power supplies (if equipped).
Disconnect the battery ground cable and wait at least one minute.
2. WARNING: To reduce the risk of serious personal injury, read and follow all warnings, cautions, notes, and instructions the supplemental restraint system (SRS) deactivation/reactivation procedure.
Deactivate the supplemental restraint system (SRS).
3. WARNING: To reduce the risk of serious personal injury, read and follow all warnings, cautions, notes, and instructions in the seat removal and installation procedure.
Remove the passenger seat.

ASSEMBLY
1. NOTE: Make sure the battery negative cable is still disconnected before continuing with the assembly portion of this procedure.
To assemble, reverse the disassembly procedure.
2. WARNING: To reduce the risk of serious personal injury, read and follow all warnings, cautions, notes, and instructions in the seat removal and installation procedure.
NOTE: Make sure the battery ground cable is still disconnected before proceeding with the installation portion of this procedure.
Install the passenger seat.
3. CAUTION:
- 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 vehicle has not been exposed to temperatures below 6°C (42°F) or above 36°C (97°F) within four hours prior to the rezeroing process. If the vehicle has been exposed to temperatures outside the temperature limits (6-36°C), the vehicle must be exposed and kept at a temperature within the limits for a minimum of four hours.
- 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 five second time period has passed after cycling the ignition switch ON before the rezeroing process.
- There are three 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.
NOTE:
- The heated seat element on the front passenger seat cushion is not serviceable separately. If a new heated seat element is needed on the front passenger seat cushion a new occupant classification sensor (OCS) service kit, equipped with a heated seat element, must be installed.
- It is necessary to rezero the OCS system when a front passenger seat cushion is disassembled, the new trim cover or a seat side shield is 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.
- When using a New Generation STAR (NGS) Tester you must use the appropriate memory card with the latest update to carry out this function. To rezero the OCS system:
- select "SERVICE BAY FUNCTIONS"
- select "RCM"
- select "SYSTEM RESET"
- select the vehicle from the menu
- view the on-screen information, then press "TRIGGER"
The NGS screen will then display "OCS RESET: REZERO." Press "DONE" (button 8) to rezero the OCS system. The NGS will return to the vehicle menu once rezeroing of the OCS system is complete.
NOTE: To rezero the OCS system using the Worldwide Diagnostic System (WDS):
- select the "Toolbox" icon
- select "Body" from the menu
- select "Restraints" from the menu
- select "Seat Weight Sensor ReZero"
After selecting "Seat Weight Sensor ReZero", follow the on-screen prompts to carry out rezeroing of the OCS system.
NOTE: 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.
4. NOTE: The ignition switch must be cycled after rezeroing the OCS system. Cycle the ignition switch from ON to OFF.
5. WARNING: The restraint system diagnostic tool is for restraint system service only. Remove from vehicle prior to road use. Failure to remove could result in injury and possible violation of vehicle safety standards.
With the restraint system diagnostic tools still installed at the remaining deployable devices, prove out the supplemental restraint system (SRS).
6. Disconnect the battery ground cable and wait at least one minute.
7. WARNING: To reduce the risk of serious personal injury, read and follow all warnings, cautions, notes, and instructions in the supplemental restraint system (SRS) deactivation/reactivation procedure.
Reactivate the supplemental restraint system (SRS).
8. Connect the battery ground cable.
9. WARNING: The restraint system diagnostic tool is for restraint system service only. Remove from the vehicle prior to road use. Failure to remove could result in injury and possible violation of vehicle safety standards.
With all the restraint system diagnostic tools removed, prove out the supplemental restraint system (SRS).
