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 status 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.
