What does this fault code mean?
The KVM (keyless vehicle module) monitors the antennas fitted to the car. The code is stored when one of the inner antennas gives too weak a signal. The keyless function then stops working completely or only partly, because the antennas are used to detect the key inside the car.
Possible causes
- A wire to the inner antennas has contact with ground
- One of the antennas is faulty
What you can do
- 1Read the code, clear it and check whether it returns
- 2With the ignition on, check that the wiring to the inner antennas is undamaged, not chafed or pinched, and that the connectors are secure
- 3Use a multimeter to check that the wire to each inner antenna is not in contact with ground (the body)
- 4With the car stationary, move the connectors and the wiring harness and see whether the fault follows the movement
- 5Have a workshop with diagnostic equipment check the antennas and replace the faulty one if the wiring is sound
Symptoms you may notice1
- Keyless functions do not work at all or work poorly
