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
