Occupant Classification Module - Removal

REMOVAL

WARNING: To avoid serious or fatal injury 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.





1. Disconnect and isolate the battery negative cable. Wait two minutes for the system capacitor to discharge before further service.

2. Reach under the front edge of the passenger side front seat cushion to access and disconnect the two seat wire harness connectors from the Occupant Classification Module (OCM) (1) connector receptacles located on the forward-facing end of the module.

3. Remove the two screws (3) that secure the OCM to the top of the mounting bracket (4) on the inboard passenger side front seat riser (2).

4. Remove the OCM from under the passenger side front seat cushion.
