Vehicle CAN Diagnosis

• CAN communication status and error counter is displayed.
• 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.

AV COMM Diagnosis

• Displays the communication status between AV control unit (mas-

ter 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.

[BOSE AUDIO WITH NAVIGATION]

DIAGNOSIS SYSTEM (AV CONTROL UNIT)

• 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 AV control unit.

• “STRG SW”, “Amp” and “XM” indicate the same status as “Audio”.

Hands-Free Phone

The hands-free phone reception volume adjustment, microphone
and speaker test, and memory erase functions are also available.

Camera Cont. (With Rear View Monitor)

The two functions of “Connection Confirmation” and “Adjust Offset of Rear View Camera” are available.
CONNECTION CONFIRMATION
Steering angle sensor, reverse signal and vehicle speed sensor can
be inspected.
