Hva betyr feilkoden?

Communication on LIN bus 3 is disturbed, so the central module cannot talk to the siren or the remote receiver. The fault may come from a wire with a short circuit or a break, or from a faulty unit on the bus. The siren and the alarm function are affected.

Open circuit in one of the LIN wires
Short circuit between the LIN wires
Faulty operation of another control module on the same LIN network

Hva du kan gjøre

1Test the alarm with the remote control and listen for the siren
2Follow the wire to the siren with a multimeter for breaks and for short circuits to ground or positive
