< BASIC INSPECTION >

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.

CASE 2

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 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:0000000006163388

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

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 Operation Instruction” for more information.

CONSULT-III CHECKING SYSTEM

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-14, "Trouble Diagnosis Flow Chart"

.
