What does this fault code mean?
The telephone module (PHM) communicates with its own built-in GPS receiver. The fault is stored when communication with the GPS receiver stops, and the cause is a damaged telephone module. This code should be checked last among the codes in the telephone module, because tracing the fault requires other codes to be cleared.
