Theory Of Operation

Each front sensor is secured with a screw to the back of the front end module carrier on either side of the cooling module and inboard of the headlamp 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 left impact sensor is to be replaced.
