Occupant Restraint Controller - Installation

INSTALLATION

WARNING:
- To avoid serious or fatal injury on vehicles equipped with airbags, disable the Supplemental Restraint System (SRS) before attempting any steering wheel, steering column, airbag, Occupant Classification System (OCS), 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 SRS. Failure to follow these instructions may result in accidental airbag deployment.
- To avoid serious or fatal injury, never strike or drop the Occupant Restraint Controller (ORC), as it can damage the impact sensor or affect its calibration. The ORC contains the impact sensor, which enables the system to deploy the Supplemental Restraint System (SRS) components. If an ORC is accidentally dropped during service, the module must be scrapped and replaced with a new unit. Failure to observe this warning could result in accidental, incomplete, or improper SRS component deployment.







1. Position the Occupant Restraint Controller (ORC) (1) over the three weld studs (5) on the top of the floor panel transmission tunnel. When the ORC is correctly positioned, the arrow on the ORC label will be pointed forward in the vehicle.
2. Install and tighten the three nuts (2) that secure the ORC to the three weld studs. Tighten the nuts to 10 N.m (7 ft. lbs.).
3. Reconnect the instrument panel (3) and body (4) wire harness connectors for the ORC to the ORC connector receptacles located on the right facing side of the module. Be certain that the latches on both connectors are each fully engaged.
4. Reinstall the floor console into the vehicle.
5. Do not reconnect the negative cable to the battery at this time. The Supplemental Restraint System (SRS) Verification Test procedure should be performed following service of any SRS component. (Refer to - Restraints - Standard Procedure).

NOTE: If the ORC is being replaced with a new unit or if the ORC software has been re-flashed, the Electronic Stability Control (ESC) system will require re-initialization using a diagnostic scan tool. Refer to the appropriate diagnostic procedures.
