Cover, Seat Cushion, Manual: Installation
Disable the airbag system before attempting any front seat diagnosis or service. Disconnect and isolate the negative battery (ground) cable and wait two minutes for the airbag system capacitor to discharge before performing further diagnosis or service. This is the only sure way to disable the airbag system. Failure to follow these instructions may result in accidental airbag deployment and possible serious or fatal injury.
The Occupant Classification System (OCS) is used in the passenger side front seat of vehicles manufactured for domestic markets. Vehicles manufactured for export markets use the Occupant Detection Sensor (ODS) instead of the OCS on the passenger side front seat.
All of the components of the OCS including the Occupant Classification Module (OCM), the Seat Weight Sensor (SWS), the plastic insulator SWS pad, the passenger seat cushion foam, the passenger seat cushion trim, the electronic pressure sensor, the OCS pressure hose, and the heat mat and vent bag (if equipped), are serviced only as a factory-calibrated and assembled unit.Any time any one of these components requires replacement for any reason, the entire calibrated OCS must be replaced and re-zeroed. Refer to the appropriate diagnostic information.
- For passenger seat equipped with OCS, position the NEW seat foam assembly onto the seat frame.
- Refer to specific instructions related to OCS installation (Refer to 08 - Electrical/8E - Electronic Control Modules/MODULE, Occupant Classification/Installation).
- For driver seat: Position the seat cover onto the seat foam and install NEW hog rings.
- Position the seat foam assembly onto the seat frame.
- Carefully align the seat venting pad to the vent motor and snap them together. Check that they are fastened together fully.
- Connect the seat heater wire harness connector.
- Fasten the trim cover retainers to the seat frame.
- Install the side shields. Refer to SIDE SHIELDS, SEAT, POWER, INSTALLATION .
- Install the seat. Refer to SEAT, REAR, INSTALLATION .
- If servicing the passenger seat, do not connect the negative battery cable at this time. The Supplemental Restraint System (SRS) Verification Test procedure should be performed following service of any SRS component. Refer to STANDARD PROCEDURE .
- Following successful completion of the SRS Verification Test procedure, perform the OCM System Verification Test procedure found in the diagnostic scan tool under Miscellaneous Functions. Refer to the appropriate diagnostic procedures.
- If this Electronic Control Unit (ECU) is being replaced with a new unit, a diagnostic scan tool MUST be used to align the PROXI configuration data into the new ECU. Follow the routine outlined in the diagnostic scan tool for PROXI Configuration Alignment under Body Control Module (BCM) Miscellaneous Functions menu.
