REMOVAL
WARNING: 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 front seat, the seat weight sensors, the
passenger or driver seat track position sensor and the 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 9077, and the Occupant
Classification System Verification Test. Refer to the appropriate diagnostic procedures.
1. Disconnect and isolate the battery negative cable.
WARNING: Wait two minutes for the airbag system reserve capacitor to discharge before beginning any airbag system or component service.
Failure to do so may result in accidental airbag deployment, serious or fatal injury.
2. Reach under the front edge of the passenger side front seat cushion to access and remove the two screws (4) that secure the Occupant
Classification Module (OCM) to the OCM bracket (1) on the passenger front seat track riser (5).
3. Lift the OCM upward far enough to disengage the locating pins on the module from the bracket, then pull the OCM down far enough to access the
module wiring connections.
4. Disconnect the two electrical connectors (3) from the OCM (2).
5. Remove the OCM (2) from under the passenger front seat.
