Hva betyr feilkoden?
The interior motion sensor (MMS) checks its own function when the alarm is activated. If it finds an internal fault, it sends an error message to the CEM, which then sets the fault code. The fault is therefore in the motion sensor itself and not in the wiring.
Mulige årsaker
- Internal fault in the motion sensor
Hva du kan gjøre
- 1Check that the motion sensor has a good power supply
- 2Activate the alarm and see whether the sensor triggers, then clear the fault code and road test
- 3If the code returns after the road test the fault is permanent; if it does not return the fault may have been intermittent
- 4Check that the connectors at the motion sensor are secure and not corroded
- 5If the fault is permanent, the motion sensor needs replacing, which is a job for a workshop
Symptomer du kan merke2
- The alarm does not respond when the sensor should trigger it
- A message appears in the text display
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
