What does this fault code mean?
The AM/FM tuner module (AFM) keeps watch on the signal from the antenna amplifier. It has registered a signal that is too high on the wiring from the amplifier, which sets the code. The fault can be checked while the radio is switched on, and the radio works poorly or not at all.
