Normal Operation
WARNING: This page is about a different car, the 2014 Lincoln MKX and 2014 Ford Edge. However, it is still accessible from the selected car via links, so may be relevant.
When the ignition is on, the video camera receives voltage through BCM fuse 34 (10A). When the gear selector in reverse, the FCDIM receives the reverse signal from the Body Control Module (BCM) over the Medium Speed Controller Area Network (MS-CAN), enabling the rear video image display. The video camera also receives the reverse signal message from BCM over the Local Interconnect Network (LIN). The LIN is a dedicated single wire communication line that carries messages between the BCM and the video camera. A pair of shielded wires carries the video signal from the video camera to the FCDIM .
- DTC B115E:08 (Camera Module: Bus Signal/Message Failure) - an on-demand DTC that sets in the BCM when there is a LIN communication fault from the video camera.
- DTC C1001:01 (Vision System Camera: General Electrical Failure) - a continuous DTC that sets in the FCDIM when no video signal is detected from the video camera when the vehicle is in reverse.
This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Fuse
- Video camera
- FCDIM
- BCM
