SERVICE INFORMATION FOR ELECTRICAL INCIDENT

INPUT-OUTPUT VOLTAGE CHART

• The voltage value is based on the body ground.

• *: If high resistance exists in the switch side circuit (caused by a single strand), terminal 1 does not detect battery voltage. Control unit

does not detect the switch is ON even if the switch does not turn ON. Therefore, the control unit does not supply power to light up the
lamp.

• The voltage value is based on the body ground.

• *: If high resistance exists in the switch side circuit (caused by a single strand), terminal 2 does not detect approx. 0V. Control unit

does not detect the switch is ON even if the switch does not turn ON. Therefore, the control unit does not control ground to light up the
lamp.

CONSULT-III CHECKING SYSTEM

Description

INFOID:0000000000956206

• When CONSULT-III is connected with a data link connector (A)

equipped on the vehicle side, it will communicate with the control
unit equipped in the vehicle and then enable various kinds of diag-
nostic tests.

• Refer to “CONSULT-III Software Operation Manual” for more infor-

mation.

CONSULT-III CHECKING SYSTEM

x: Applicable

CONSULT-III Data Link Connector (DLC) Circuit

INFOID:0000000000956208

INSPECTION PROCEDURE

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

NOTE:
The DDL1 and DDL2 circuits from DLC pins 12, 13, 14 and 15 may be connected to more than one system. A
short in a DDL circuit connected to a control unit in one system may affect CONSULT-III access to other sys-
tems.

Function test

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

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
