WARNING: This page is about a different car, the 2012 Ford Pickup, 2012 Ford F550 Super Duty, 2012 Ford F450 Super Duty, and 2012 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.

When the ignition switch is in the RUN position, the video camera receives voltage. For vehicles without navigation, with the gear selector in REVERSE (R), a reverse signal message is sent to the auto-dimming interior mirror over the Local Interconnect Network (LIN), enabling the system. The LIN is a dedicated single wire communication line that sends and receives network messages from the Body Control Module (BCM) to the auto-dimming interior mirror for the video camera, compass and electrochromatic mirror systems. For vehicles with navigation, with the gear selector in REVERSE (R), a reverse signal is sent from the BCM to the Audio Control Module (ACM) over the Medium Speed Controller Area Network (MS-CAN), enabling the system. A pair of shielded wires carries the video signal from the video camera and displays an image on the left portion of the auto-dimming interior mirror (for vehicles without navigation) or in the display of the ACM (for vehicles with navigation).

DTC C1001:01 (Vision System Camera: General Electrical Failure) - a continuous DTC that sets in the ACM when no video signal is detected for more than 3 seconds when the vehicle is in REVERSE (R).

This pinpoint test is intended to diagnose the following:

Fuse
Wiring, terminals or connectors
Video camera
Auto-dimming interior mirror (without navigation)
ACM (for vehicles with navigation)
