DIAGNOSIS SYSTEM (ITS CONTROL UNIT)
CONSULT Function (AVM)INFOID:0000000009951637
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”, potentiall y causing a discharged 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-89, "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

- 1 - 39: It increases like 0 → 1 → 2 ··· 38 → 39 after returning to the normal condition whenever the ignition
switch OFF → ON. It returns to 0 when a malfunc tion is detected again in the process.
- If it is over 39, it is fixed to 39 unt il the self-diagnosis results are erased.

• LDW system setting is not selectable on the navigation screen.
• NOTE:
When the ignition switch is in ACC posit ion, LDW system setting cannot be changed.
- “Lane Departure Warning” is not indicated on the navigation screen.
- The switching between ON and OFF cannot be per formed by operating the navigation system.
- The item of “Lane Departure Warning” on the navigation screen is not active.
• After turning ON the ignition switch or starting t he engine, LDW setting of the navigation system cannot be
selected for several tens of sec onds under the following conditions:
- After replacing AV control unit.
- After erasing connection histor y of the navigation system.
- After erasing self-diagnosis results of AV control unit.
• The LDW or LDP system setting differs from the one set at the previous driving.
NOTE:
Turn OFF the ignition switch and wait for 5 seconds or more.
Diagnosis ProcedureINFOID:0000000009464792
1.CHECK LDW SYSTEM SETTING
1. Start the engine.
2. Check that the LDW system settings is selectable on the navigation screen.
Is the inspection result normal?
YES >> GO TO 3.
NO >> GO TO 2.
2.PERFORM THE SELF-DIAGNOSIS
1. Perform “All DTC Reading” with CONSULT.
2. Check if the DTC is detected in self-diagnosis re sults of “AVM”, “MULTI AV” and “METER/M&A”. Refer to
the following.
-AVM: DAS-89, "DTC Index"
- MULTI AV (with BOSE): AV-328, "DTC Index"
- MULTI AV (without BOSE): AV-231, "DTC Index"
- METER/M&A: MWI-27, "DTC Index"
Is any DTC detected?
YES >> Repair or replace malfunctioning parts.
NO >> Inspection End.
3.CHECK DATA MONITOR OF ITS CONTROL UNIT
Check that “LDW SELECT” operates normally in “DATA MONITOR” of “AVM” with CONSULT.
Is the inspection result normal?
YES >> Refer to DAS-83, "CONSULT Function (AVM)".
NO >> GO TO 4.
4.CHECK MULTIFUNCTION SWITCH
Operate the multifunction switch to check that the audio, navigation system, and air conditioner operate prop-
erly.
Is the inspection result normal?
YES >> Replace the ITS control unit. Refer to DAS-68, "Removal and Installation".
