Hva betyr feilkoden?

The central module has detected that LIN communication with the siren or the remote receiver is blocked. The fault may lie in the wiring, in a damaged communication device or in another control module on the same network. As a result the siren works erratically or not at all, and the alarm cannot be operated.

Mulige årsaker

Internal fault in another control module on the same part of the LIN network
Open circuit in one of the LIN wires
Short circuit between the LIN wires

Hva du kan gjøre

1Try locking and unlocking the car with the remote control, and listen for the siren
2With a multimeter, check that the wire to the siren has no break and no contact with the car body or the battery positive
3Make the same check on the wire to the remote receiver
4Have a workshop read which control module does not respond, and replace it

Symptomer du kan merke2

The siren sounds erratically or not at all
