The parking assistance camera module (PAC) receives the picture from the rear camera. The fault is set when the control module gets no video signal from the rear camera. The fault can come from poor contact or oxidation at the connections to the rear camera, an open or short circuit in the wire, or a damaged rear camera or parking assistance camera module (PAC).
