Occupant Restraint Controller: Removal
WARNING:
On vehicles equipped with the Occupant Classification System (OCS), never replace both the Occupant Restraint Controller (ORC) and the Occupant Classification Module (OCM) at the same time. If both require replacement, replace the OCM first. Then perform the Airbag System test (Refer to ELECTRICAL/RESTRAINTS - DIAGNOSIS AND TESTING - AIRBAG SYSTEM) including an ignition-On time of at least one minute before replacing the ORC. Both the ORC and the OCM store OCS calibration data, which they transfer to one another during the first minute of ignition-On time after one of them is replaced. If both modules are replaced at the same time, an irreversible fault will be set in both modules.
- Open hood, 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, personal injury or death.
- Wait two minutes for the system reserve capacitor to discharge before beginning any system or component service.
