Description And Operation: Description
The Occupant Restraint Control (ORC) module, located on the floor of the central tunnel under the dashboard center console, monitors the impact and occupant sensors and activates restraint system devices in the event of an impact. The ORC also contains impact sensors that are used to determine the level of deployment and to verify the information received from the remote sensors.
An arrow printed on the ORC label indicates the installation orientation. The arrow must point toward the front of the vehicle. The ORC must be installed correctly for correct restraint system operation.
The ORC module will set a specific DTC which cannot be deleted, not even using the diagnostic tool. This will happen when you reach:
- 2 activations of the tensioners
- 2 activations of the side bags
- 1 activation of the tensioners plus the front airbags; all versions
- Any other combination of the above mentioned cases until one of the limits is reached.
When one of the above mentioned limits is reached, the ORC module will have to be replaced.
The impact sensor and safing sensor internal to the ORC are calibrated for the specific vehicle, and are only serviced as a unit with the ORC. In addition, there are unique versions of the ORC for vehicles with or without certain optional Supplemental Restraint System (SRS) components. The ORC cannot be repaired or adjusted and, if damaged or ineffective, it must be replaced.
