What does this fault code mean?
The keyless vehicle module (KVM) measures the antenna signal while the car is being driven. If one or more inner antennas give too weak a signal, the code is stored, and the keyless functions can become poor or disappear entirely.
Possible causes
- One of the inner antennas has a wire in contact with ground
- One of the antennas is broken
What you can do
- 1Read the code, clear it and check whether it returns
- 2Disconnect the battery negative lead, then inspect the wiring to the inner antennas for damage, chafing and pinching
- 3Use a multimeter to check that the wires to the inner antennas are not connected to ground (the body)
- 4Make sure the connectors are firmly seated and free from corrosion
- 5Have a workshop with diagnostic equipment check the antennas and replace the broken antenna if the wiring is sound
Symptoms you may notice1
- Keyless function is reduced or absent
