Was bedeutet der Fehlercode?
Although the code is named too high signal, it means that the right-hand GDL module receives too little supply voltage. A broken signal wire between the CEM and the module can give the same message, so both are checked.
Mögliche Ursachen
- Supply voltage to the right-hand GDL module is too low
- Open circuit in the signal wire running to the right-hand GDL module
Was Sie tun können
- 1With the ignition off, check that the connectors at the right-hand module are clean, firmly fitted and undamaged
- 2Use a multimeter to check that the signal wire between the CEM and the right-hand module is not broken and has no contact with ground
- 3Check that the right-hand module has a good earth connection, meaning the earth connection is tight and clean
- 4With the engine running and the low beam on, use a multimeter to check that the supply voltage is not below normal. The supply is shared with the left-hand module
- 5If the fault remains, have a workshop check the supply and the signal wire
Symptome, die Sie bemerken können1
- The low beam does not work
