What does this fault code mean?
The signal from the GPS antenna is registered as too high, and the fault is intermittent, so it may have come and gone. It applies to cars in the EU/OS version. A message appears in the text display when it happens. The cause can be a short circuit to supply voltage in the antenna cable.
