DIAGNOSIS SYSTEM (AV CONTROL UNIT)

• 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.

NOTE:
“???” indicates UNKWN.

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” is pressed.
