Hva betyr feilkoden?
The CEM has found the horn relay shorted to ground. The horn does not work in this case. The fault is most often caused by a broken relay.
Mulige årsaker
- A damaged relay
Hva du kan gjøre
- 1Check the horn fuse in the engine bay fusebox. If it has blown, replace it once
- 2Replace the horn relay with an identical one. If the horn then works, the old relay was probably faulty
- 3Check that the connectors at the relay and at the CEM are seated and not corroded
- 4With the relay removed, use a multimeter to check that the horn wire is not short-circuited to ground
- 5After the work, test the horn and check that the code does not return
Symptomer du kan merke1
- The horn does not work
