What does this fault code mean?
The infotainment control module (ICM) and the integrated audio module (IAM) exchange a video signal over an LVDS link. The code is set when ICM detects a break in that signal. Although it is labelled bus off, the code describes an open circuit in the video path to video input D.
Possible causes
- Incorrect sync signal from the LVDS input at the control module
- Loose contact in the video cable where it enters the control module
- Damaged wire between the control module and the LVDS input
What you can do
- 1Check that the fuses are intact. Their positions are in the owner's manual or on the fuse box cover
- 2Test the affected functions with buttons, controls or a short drive
- 3Check the connectors at the LVDS input and the audio module are firmly seated and free from oxidation
- 4With a multimeter, confirm the video wire is continuous between the two modules. With a diagnostic tool, run the quick test and check whether the code returns
