What does this fault code mean?
The front display module reads the picture feed arriving at video input 2, and the fault code is set when that feed is wrong. A broken signal cable or a short to earth or supply voltage can be behind the fault. The front display does not work while the fault is active.
Possible causes
- Open circuit on the signal cable
- The signal cable is shorted to earth
- The signal cable is shorted to supply voltage
What you can do
- 1Check that the fuses are intact. Their location is in the owner's manual or on the cover of the fuse box
- 2Road test the car or use the controls to see whether the display works
- 3Use a multimeter to check that the signal cable to video input 2 is intact and not shorted to earth or supply voltage
