Was bedeutet der Fehlercode?

The keyless vehicle module (KVM) monitors the antennas once the car is moving fast enough. The code is stored when the signal from one of the inner antennas becomes too weak. The inner antennas share one driver circuit in the module, and the keyless functions then work poorly or not at all.

Mögliche Ursachen

A wire to one of the inner antennas has a short to ground
One of the inner antennas is faulty

Was Sie tun können

1Read the code, clear it and test the keyless functions with the ignition on
2With the ignition off, inspect the wiring to the inner antennas for damage and chafing, and make sure the connectors are secure
3Use a multimeter to check that the wires to the antennas are not in contact with ground (the body)
4With the car stationary, gently move the connectors and the wiring harness and see whether the fault follows
5Have a workshop with diagnostic equipment check the antennas and replace the faulty one if the wiring is sound
