Hva betyr feilkoden?
The fault is stored when the signal to the horn relay is too high while the horn is not activated. The fault concerns an open circuit or poor contact in the connections.
Mulige årsaker
- Contact resistance, oxidation or poor contact in the connections
- Open circuit in the relay drive circuit
Hva du kan gjøre
- 1Check that the fuse for the horn is intact
- 2Press the horn to see whether it works, then clear the fault code and road test
- 3Check the connectors at the horn relay and at the CEM, and clean or press in any that are loose
- 4Use a multimeter to check that the wire to the relay is continuous between the connector ends
- 5If the fault returns, have a workshop with diagnostic equipment fault-trace the CEM, the relay and the wiring
Symptomer du kan merke1
- The horn does not work
Hva feilen kan påvirke2
- The function switches off permanently after 100 driving cycles where the fault was detected
- Erasing the fault codes resets the output
