Theory Of Operation

Each front sensor is secured with a screw to the backs of the right and left vertical members of the radiator support within the engine compartment. Impact sensors perform their own self test using power supplied by the Occupant Restraint Controller (ORC) then communicate this status back to the module. The repair of this fault centers on verifying the integrity of the sensor's internal circuitry and software validity. If the scan tool shows this DTC has a Stored history of setting then the front right impact sensor is to be replaced.
