< SYSTEM DESCRIPTION >[ITS CONTROL UNIT]
DIAGNOSIS SYSTEM (ITS CONTROL UNIT)
DIAGNOSIS SYSTEM (ITS CONTROL UNIT)
CONSULT Function (AVM)INFOID:0000000009464652
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-20, "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
Monitored item [Unit] Description
ST ANGLE SENSOR SIGNAL
[On/Off] Indicates [On/Off] status as judged from ITS control unit (Angle sensor transmits angle signal
through CAN communication)
REVERSE SIGNAL
[On/Off] Indicates [On/Off] status as judged from ITS control unit (TCM transmits reverse signal
through CAN communication)
VEHICLE SPEED SIGNAL
[On/Off] Indicates vehicle speed
calculated from ITS control unit through CAN communication [ABS ac-
tuator and electric unit (control unit) transmits vehicle speed signal (wheel speed) through
CAN communication]
CAMERA SWITCH SIGNAL
[On/Off] Indicates [On/Off] status of camera switch signal as judged from ITS control unit
CAMERA OFF SIGNAL
[On/Off] Indicates [On/Off] status of camera OFF signal as judged from ITS control unit
ST ANGLE SENSOR TYPE
[Absolute/Not] Indicates whether steering angle sensor type is absolute or not (ON means “controlling”)
STEERING GEAR RATIO TYPE
[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
R-CAMERA COMM LINE
[OK/Not] Indicates the condition of the rear camera communication line whether transmitting properly
through dedicated ITS communication lines
PUMP COMM STATUS
[OK/NG] Indicates the state of the communication signal from pump control unit
