Occupant Classification Module - Installation

INSTALLATION

WARNING: To avoid serious or fatal injury on vehicles equipped with airbags, disable the Supplemental Restraint System (SRS) before attempting any steering wheel, steering column, airbag, Occupant Classification System (OCS), seat belt tensioner, impact sensor or instrument panel component diagnosis or service. Disconnect and isolate the battery negative (ground) cable, then wait two minutes for the system capacitor to discharge before performing further diagnosis or service. This is the only sure way to disable the SRS. Failure to follow these instructions may result in accidental airbag deployment.







NOTE: All of the components of the Occupant Classification System (OCS) including the Occupant Classification Module (OCM), the Seat Weight Sensor (SWS) (also known as the seat weight bladder), the upper and lower protective plastic liners, the passenger seat cushion foam, the electronic pressure sensor and the OCS pressure hose are serviced only as a factory-calibrated and assembled unit. Any time any one of these components requires replacement for any reason, discard all of the removed OCS components including the OCM with integral and internal electronic pressure sensor, the pressure hose, the SWS, the upper and lower protective plastic liners and the seat cushion foam and replace them with the entire contents of the factory-calibrated OCS service replacement package.

1. Position the Seat Weight Sensor (SWS) (also known as the seat weight bladder) (3), the upper and lower protective plastic liners (8), the retainer (7), the Occupant Classification System (OCS) pressure hose and the Occupant Classification Module (OCM) with integral electronic pressure sensor (4) to the top of the seat cushion pan (6) as a unit.
2. Lift the back of the SWS and liners far enough to access and insert the OCM and pressure hose through the clearance hole to the underside of the seat cushion pan. Be certain the pressure hose is not pinched or kinked.
3. Install the two push-in plastic fasteners (2) that secure the SWS and liners to the seat cushion pan.
4. Position the foam (1) onto the seat cushion pan.
5. Reinstall the trim cover onto the passenger seat cushion..
6. From the underside of the seat cushion, snap the OCM (4) onto the blade of the stamped metal mounting bracket (5) beneath the inboard front corner of the seat cushion. Route the pressure hose away from sharp or moving objects and be certain the hose is not kinked.
7. Reconnect the seat wire harness connector to the OCM beneath the inboard front corner of the seat cushion.
8. Reinstall the passenger seat into the vehicle.
9. Do not reconnect the negative cable to the battery at this time. The Supplemental Restraint System (SRS) Verification Test procedure should be performed following service of any SRS component. (Refer to - Restraints - Standard Procedure).
10. 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.
