Seat Occupant Classification Module - Air Bag: Service and Repair
Installation
INSTALLATION
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. Reach under the front edge of the passenger side front seat cushion to carefully position the Occupant Classification Module (OCM) (1) to the top
of the mounting bracket (4) on the inboard passenger side front seat riser (2). When the OCM is correctly positioned, the connector receptacles on
the module will be pointed forward.
2. Install and tighten the two screws (3) that secure the OCM to the mounting bracket. Tighten the screws to 2 Nm (20 in. lbs.).
3. Reconnect the two seat wire harness connectors to the OCM connector receptacles located on the forward-facing end of the module. Be certain
that the latches on each connector are fully engaged.
4. Do not reconnect the battery negative cable at this time. The supplemental restraint system verification test procedure should be performed
following service of any supplemental restraint system component.
5. Following successful completion of the supplemental restraint system verification test procedure, perform the Occupant Classification System
Verification Test using a diagnostic scan tool. Refer to the appropriate diagnostic procedures.
