What does this fault code mean?
The keyless vehicle module (KVM) monitors the connection to the outer antennas on the right side of the car when the car reaches a certain speed. The code is stored when the signal from the antenna circuit is faulty, or when it is missing altogether. The keyless functions then work poorly or stop working.
Possible causes
- At least one of the outer right-hand antennas is faulty or not connected
- One of the outer right-hand antennas is faulty
- The outer right-hand antenna is damaged
What you can do
- 1Read and note the code, clear it and road test the car to see whether it returns
- 2Disconnect the battery negative lead and inspect the wiring to the antennas in the right door handle for damage and chafing
- 3Use a multimeter to check that the wires to the antennas have no short to ground or supply voltage, and no open circuit
- 4Make sure the connections at the antennas and at the KVM are firmly seated and free from oxidation
- 5Have a workshop with diagnostic equipment check the antennas and the KVM and replace the faulty part
Symptoms you may notice1
- Keyless functions do not work at all or work poorly
