DIAGNOSIS SYSTEM (AV CONTROL UNIT)

• Use this mode to adjust the guide line display position of the rear

view monitor if necessary after removing the rear view monitor

camera.

CAUTION:

After the adjustment, never perform other operations for one

minute.

Factory Configuration Confirmation

• Configuration stored in the AV control unit can be checked.

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” is pressed.

NOTE:

“???” indicates UNKWN.

• 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:

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

removed.)

Initialize Settings

“User Data Initialization” and “Accessory Number Initialization” are

possible.

CAUTION:

• Never perform Accessory Number Initialization except when

configuration is unsuccessful. 

• Accessory Number Initialization requires configuration. For

details, refer to 

AV-276, "CONFIGURATION (AV CONTROL

UNIT) : Description"

.

CONSULT Function

INFOID:0000000009174534

CAUTION:

After disconnecting the CONSULT vehicle interface (VI) from the data link connector, the ignition must

be cycled OFF 

→ ON (for at least 5 seconds) → OFF. If this step is not performed, the BCM may not go

to ”sleep mode”, potentially causing a discharged battery and no-start condition. 

CONSULT FUNCTIONS

CONSULT performs the following functions via communication with the AV control unit.
