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.
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.
• If it resets, the error counter is erased.
Delete Unit Connection Log
Deletes any unit connection records and error records from the AV
control unit memory. (Clear the records of the unit that has been
