Hva betyr feilkoden?
The module (REM) monitors the siren (BBS) through check messages. The fault is stored if the siren does not answer the communication or answers with incorrect information, and the result can then be a false alarm.
Mulige årsaker
- Open circuit in the signal wire to the siren
- Faulty connectors in the rear electronic module (REM), the central electronic module (CEM) or the siren
- Leaking battery acid in the siren, which causes interference on the LIN network
- Internal fault in the siren
Hva du kan gjøre
- 1Use a multimeter to check that the signal wire to the siren has no break and is not shorted to ground or to supply voltage
- 2Look at the siren for signs of leaking battery acid, and check that the connectors are secure
- 3Clear the fault code, close all doors, activate the alarm and read whether the fault code comes back
- 4If the fault remains, have a workshop replace the siren
Symptomer du kan merke2
- False alarm
- If the siren has an angle sensor: the angle sensor does not activate
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
