Co oznacza ten kod błędu?
The central electronic module (CEM) feeds the right low beam through an output. The code is set if the signal to the low beam lamp is too high or missing entirely, which can be caused by a short to voltage or an open circuit in the signal wire.
Możliwe przyczyny
- The signal cable to the right low beam lamp is shorted to voltage
- Open circuit on the signal cable
Co możesz zrobić
- 1Read and clear the code, then switch on the low beam and see whether the lamp lights
- 2Check that the fuse for the right low beam is intact
- 3Use a multimeter to see whether the signal cable has voltage with the ignition off
- 4Use a multimeter to check that the signal cable is continuous between its two ends
- 5If the wire is intact, have a workshop with diagnostic equipment check the module output
Objawy, które możesz zauważyć3
- Warning symbol and text message in the display
- The bulb failure warning in the instruments comes on or behaves abnormally
- The right low beam does not work
