Work support

This mode enables a technician to adjust some devices faster
and more accurately by following indications on CONSULT-II.

Self-diagnostic results

Self-diagnostic results can be read and erased quickly.

Trouble diagnostic record

Current self-diagnostic results and all trouble diagnostic
records previously stored can be read.

Data monitor

Input/Output data in the ECU can be read.

CAN diagnostic support
monitor

The communication condition of CAN communication line can
be read.

Active test

Diagnostic Test Mode in which CONSULT-II drives actuators
apart from ECU shifting some parameters in a specified range.

Function test

This mode can show results of self-diagnosis of ECU with either
"OK" or "NG". For engines, more practical tests regarding sen-
sors/switches and/or actuators are available.

INFOID:0000000001691474

INSPECTION PROCEDURE

If the CONSULT-III cannot diagnose the system properly, check the following items.

NOTE:
The CAN and DDL2 circuits from DLC pins 6, 7 and 14 may be connected to more than one system. A short in
any circuit connected to a control unit in one system may affect CONSULT-III access to other systems.

Symptom

Check item

CONSULT-III cannot access
any system.

• CONSULT-III DLC power supply circuit (Terminal 8) and ground circuit (Terminal 4)

CONSULT-III cannot access in-
dividual system. (Other sys-
tems can be accessed.)

• Power supply and ground circuit for the control unit of the system (For detailed circuit, refer to wiring

diagram for each system.)

• Open or short circuit between the system and CONSULT-III DLC (For detailed circuit, refer to wiring

diagram for each system.)

• Open or short circuit CAN communication line. Refer to

LAN-22, "Trouble Diagnosis Flow Chart"
