Module, Occupant Restraint Control (Orc): Installation
To avoid serious or fatal injury on vehicles equipped with side curtain airbags, disable the Supplemental Restraint System (SRS) before attempting any Occupant Restraint Controller (ORC) diagnosis or service. The ORC may contain a rollover sensor, which enables the system to deploy the side SRS components in the event of a vehicle rollover event. If an ORC containing a rollover sensor is accidentally rolled during service while still connected to battery power, the side SRS components will deploy. 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 take the proper precautions could result in accidental airbag deployment.
To avoid serious or fatal injury on vehicles equipped with airbags, disable the Supplemental Restraint System (SRS) before attempting any steering wheel, steering column, airbags, airbag curtains, knee blocker, seat belt tensioner, impact sensor or instrument panel component diagnosis or service. Disconnect the Intelligent Battery Sensor (IBS)/negative battery cable assembly from the negative battery post, 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 take the proper precautions could 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.
The ORC module and the bracket will be replaced with a new ORC and bracket together. Do not replace the ORC module separately.
- Position the Occupant Restraint Controller (ORC) module and bracket as unit for installation.NOTE:
In order to avoid rotation of the bracket during installation, the vehicle-forward right side bolt (1) and vehicle-rearward left side bolt (3) need to be hand started.
- Following the torque sequence for the bolts, you will need to torque the bolts to the proper torque specifications. Refer to TECHNICAL SPECIFICATIONS
.
- After latching the wire harness connectors to the ORC, latch the Connector Position Assurance (CPA) connector on both connectors (1).CAUTION:
The lever arms of the wire harness connectors for the ORC MUST be in the unlatched position before they are inserted into their connector receptacles on the ORC or they may become damaged.
- Install the center console. Refer to CONSOLE, CENTER, INSTALLATION .
- Do not connect the negative battery cable at this time. The Supplemental Restraint System (SRS) Verification Test procedure should be performed following service of any SRS component. Refer to SUPPLEMENTAL RESTRAINT SYSTEM VERIFICATION TEST .
Service replacement ORC modules are shipped in a LOCKED OUT state and after installed will set an ORC UNLOCKED - ALL DEPLOYMENT DISABLED fault. Use a diagnostic scan tool to access the ORC module and go to the MISCELLANEOUS FUNCTIONS menu item to perform the MODULE INITIALIZATION procedure to erase the fault and initialize the new replacement ORC.
