What does this fault code mean?
The KVM (keyless vehicle module) monitors the antennas on the right side of the car once it reaches a certain speed. The code is stored when no signal comes from the outer right-hand antennas. The keyless functions then work poorly or not at all.
Possible causes
- Part of the circuit for the outer right-hand antennas is not connected
- One of the outer right-hand antennas is faulty
- The outer right-hand antenna is damaged
What you can do
- 1Read the code, clear it and road test the car
- 2Disconnect the battery negative lead and check that the antennas in the right door handle are connected and that the wiring is complete
- 3Use a multimeter to check that there is no open circuit in the wiring between the KVM and the outer right-hand antennas
- 4Check the connection to the KVM and to the antenna for loose contact and oxidation
- 5Have a workshop with diagnostic equipment check and replace whichever part is faulty, the antenna or the module
Symptoms you may notice1
- Keyless functions do not work at all or work poorly
