Occupant Classification Module: Installation
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, 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, and the Occupant Classification System Verification Test. Refer to the appropriate diagnostic procedures.
- Carefully position the Occupant Classification Module (OCM) (4) to the OCM bracket (1) on the underside of the passenger side front seat cushion frame. When the OCM is correctly positioned, the connector receptacles on the module will be pointed inboard in the vehicle.
- Install and tighten the two screws (2) that secure the OCM to the OCM bracket. Tighten the screws to 2 N.m (15 in. lbs.).
- Reconnect the two seat wire harness connectors (3) to the OCM connector receptacles located on the inboard facing side of the module. Be certain that the latches on both connectors are each fully engaged.
- 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. (Refer to ELECTRICAL/RESTRAINTS - STANDARD PROCEDURE - VERIFICATION TEST) .
- 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.
