Normal Operation

WARNING: This page is about a different car, the 2010 Mercury Mariner and 2010 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.

With the ignition switch in the RUN position, the video camera receives voltage. For vehicles without navigation, with the gear selector in REVERSE (R) position, a reverse voltage signal is sent to the auto-dimming interior mirror. For vehicles with navigation, with the gear selector in REVERSE (R) position, a reverse signal is sent from the Instrument Cluster (IC) to the Audio Control Module (ACM) over the Medium Speed Controller Area Network (MS-CAN), enabling the system. The video signal from the video camera displays an image on the left portion of the auto-dimming interior mirror (for vehicles without navigation) or displays an image on 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:

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