Hva betyr feilkoden?
Disturbance on the LIN bus stops the central module from reaching the siren or the remote receiver. The cause may lie in the wiring, in a faulty unit, in a short circuit or in a break in the wires. The siren may then sound erratically or go silent completely, and the alarm cannot be controlled.
Mulige årsaker
- Open circuit in one of the LIN wires
- Internal fault in another control module on the same part of the LIN network
- Short circuit between the LIN wires
Hva du kan gjøre
- 1Test the alarm twice with the remote control and see whether the siren responds each time
- 2With a multimeter, check the wires to the siren and the remote receiver for breaks and for contact with ground or voltage
- 3Look at the connections at the siren and the remote receiver for corrosion or loose connectors
- 4Clear the fault code and road test to see whether it returns
- 5If the wires are intact, have a workshop find which unit is silent and replace it
Symptomer du kan merke2
- The siren works intermittently or not at all
- The alarm cannot be armed or disarmed
