Co oznacza ten kod błędu?
The keyless vehicle module (KVM) monitors the link to the remote keyless entry receiver, which picks up the key fob signals and handles the keyless functions. The code is stored when the module registers that the signal is incorrect. Because the receiver no longer responds correctly, the remote control stops working, and both the cabling and the receiver need checking.
