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.
NOTE:
“???” indicates UNKWN.
Delete Unit Connection Log
