DIAGNOSIS SYSTEM (ITS CONTROL UNIT)
DIAGNOSIS SYSTEM (ITS CONTROL UNIT)
CONSULT Function (AVM)INFOID:0000000009951646
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 di scharged battery and no-start condition.
APPLICATION ITEMS
CONSULT performs the following functions via CAN communication using ITS control unit.
SELF DIAGNOSTIC RESULT
Refer to DAS-164, "DTC Index".
DATA MONITOR
Diagnosis mode Description
Self Diagnostic Result Displays the name of a malfunctioning system stored in the ITS control unit
Data Monitor Displays ITS control unit input/output data in real time
Work support Displays causes of automatic system cancellation occurred during system control
Active Test Enables an operational check of a load by transmitting a driving signal from the ITS control unit to
the load
ECU identification Displays ITS control unit part number
Configuration The vehicle specification can be written when replacing the ITS control unit

[Type 0/1] Indicates the type of the steering gear ratio (type 1 or 2)
STEERING POSITION
[LHD/RHD] Indicates the steering position (LHD or RHD)
REAR CAMERA IMAGE SIGNAL
[OK/Not] Indicates the status of the rear camera image as read from ITS control unit through dedicated
ITS communication lines
WASH SW
[ON/OFF] Indicates the state of the wash switch indicator output
R-CAMERA COMM STATUS
[OK/Not] Indicates the status of the rear camera communication status as read from ITS control unit
through dedicated ITS communication lines
