 Vehicle AV COMM Diagnostics This screen shows the status of systems within the AV COMM (Audio/Video Communications) systems 
AV COMM Diagnosis • Displays the communication status between AV control unit (master unit) and each unit. • The error counter displays “OK” if any malfunction was not detected in the past and displays “0” if a malfunction is detected. It increases by 1 if the condition is normal at the next ignition switch ON cycle. The upper limit of the counter is 39. • The error counter is erased if “Reset” is pressed. NOTE: • Any units with “—” displayed have no history of vehicle connection. • “Audio” and “Amp” indicate the same status because “Amp” indicates the status of the amplifier integrated in the AV control unit. • “STRG SW”, “Amp”“XM” indicate the same status as “Audio”.
