DIAGNOSIS SYSTEM (AV CONTROL UNIT)

AV COMMUNICATION

When “AV communication” of “CAN Diag Support Monitor” is selected, the following function will be performed.

ECU IDENTIFICATION

The part number of AV control unit is displayed.

SELF DIAGNOSIS RESULT

• In CONSULT-III self-diagnosis, self-diagnosis results and error history are displayed simultaneously.
• The timing is displayed as “0” if any of the error codes [U1000], [U1010], [U1300] or [U1310] are detected.

The counter increases by 1 if the condition is normal at the next ignition switch ON cycle.
