Occupant Classification Module: Removal
WARNING:
To avoid personal injury or death, on vehicles equipped with airbags, disable the supplemental restraint system before attempting any steering wheel, steering column, airbag, occupant classification system, 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 supplemental restraint system. Failure to take the proper precautions could result in accidental airbag deployment.
NOTE:
A non-calibrated Occupant Classification Module (OCM) is available for separate service replacement. The OCM and all of the other components of the Occupant Classification System (OCS) including the passenger side front seat, the seat weight sensors, and the passenger seat adjusters, cushion, back, frame, foam, springs, and wiring harness are a factory-calibrated and assembled unit. Any time any one of these components is removed or replaced for any reason, the OCM must be re-calibrated using a diagnostic scan tool, the Occupant Classification Seat Weight special tool, and the Occupant Classification System Verification Test. Refer to the appropriate diagnostic procedures.
- Disconnect and isolate the battery negative cable. Wait two minutes for the system capacitor to discharge before further service.
- Remove the passenger side front seat from the vehicle. (Refer to BODY/SEATS/SEAT - FRONT - REMOVAL) .
- Disconnect the seat wire harness (2) connector from the Occupant Classification Module (OCM) connector receptacle (3) located on the forward facing side of the module.
- Remove the two screws (4) that secure the OCM to the bracket (1) on the underside of the passenger side front seat riser frame.
- Remove the OCM from the passenger side front seat.
