Description And Operation: Description
The Occupant Restraint Control (ORC) module, located on the floor tunnel under the instrument panel 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:
- 3 activations of the tensioners, Europe-Middle East-Africa (EMEA) only
- 2 activations of the tensioners, NAFTA only
- 3 activations of the side airbags, EMEA only
- 2 activations of the side airbags, NAFTA only
- 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.
In EMEA versions the front passenger airbag can be deactivated via the vehicle menu. A dedicated LED indicates its deactivation.
The yaw or lateral acceleration sensor is installed inside the ORC module and is used for the correct operation of the vehicle dynamic stability functions.
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.
