What does this fault code mean?
This code concerns the BLIS system, where a camera sits in each external mirror. The passenger door module (PDM) talks to the camera on the passenger side over LIN and monitors the power supply to the LED. The fault code is stored when the supply wire to the LED is shorted to ground.
Possible causes

What you can do
- 1Start the engine and activate the BLIS system; check that the LED flashes three times
- 2Look at the LED connector and wire for chafing or damage

- 4If the fault code does not return, no further action is needed; otherwise have a workshop check the LED and its wiring
