Pinpoint Test H: The Rear Video Is Inoperative
Normal Operation
For vehicles without navigation, with the gear selector in REVERSE (R) position, a reverse voltage signal is sent to the auto-dimming interior mirror and the video camera supplying power to the system. The video camera signal is sent to the auto-dimming interior mirror. The video signal from the video camera displays an image on the LH side of the auto-dimming interior mirror.
For vehicles with navigation, with the gear selector in the REVERSE (R) position, a reverse voltage signal is sent to the video camera supplying power to the camera. A reverse signal is also sent from the Instrument Panel Cluster (IPC) 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 Front Display Interface Module (FDIM).
- DTC C1001:01 (Vision System Camera: General Electrical Failure)- a continuous DTC that sets in the ACM (Audio Control Module) 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)
- FDIM (Front Display Interface Module) (with navigation)
