Hva betyr feilkoden?
The central electronic module (CEM) supplies the number plate lighting and monitors the output. The fault shows that the signal from the output is too high, which can be caused by a short to voltage or a break in the wiring.
Mulige årsaker
- Contact resistance, oxidation or a loose connection in the connections
- Break in the signal wire
- The signal wire is shorted to voltage
- The supply wire is shorted to voltage
Hva du kan gjøre
- 1Clear the code and check whether it returns when the number plate light is switched on
- 2Check that the fuse for the number plate lighting is intact
- 3Check that the connectors at the lamp are fully engaged and not corroded
- 4Use a multimeter (ignition off, connector unplugged) to check that the wire is not at battery voltage and has no break
- 5If you have a diagnostic tool, activate the number plate lighting with the tool and check whether it comes on
- 6If the fault remains, have a workshop check the wiring and the lamp
Symptomer du kan merke1
- The number plate lighting does not work
Hva feilen kan påvirke2
- The function is switched off permanently after several operating cycles in which the fault was detected
- Clearing the fault codes resets the output
