Was bedeutet der Fehlercode?

Communication on LIN bus 14 has been interrupted, so the central module cannot reach the units on the bus. The cause is either a short circuit or a break in the bus wiring. The driver does not notice it, but the fault should still be investigated.

Mögliche Ursachen

Open circuit in one of the LIN wires
Short circuit between the LIN wires

Was Sie tun können

1Check that the fuses are intact. The owner's manual shows where they are
2If possible, test the car's functions with the buttons and controls to see whether anything behaves oddly. If nothing does, the fault may be intermittent
3Have a workshop with diagnostic equipment read the fault code together with the frozen values, to see when it occurred
4If the bus wiring is broken or shorted, have a workshop repair the wiring
