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. 0 V. 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/GST CHECKING SYSTEM
Description
INFOID:0000000005516119
• When CONSULT-III/GST is connected with a data link connector
(A) equipped on the vehicle side, it will communicate with the con-
trol unit equipped in the vehicle and then enable various kinds of
diagnostic tests.
• Refer to “CONSULT-III Software Operation Manual” for more infor-
mation.

CONSULT-III/GST CHECKING SYSTEM
If the CONSULT-III/GST 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.
If the GST cannot operate properly, check the circuit based on the information of SAE J1962 and ISO 15031-
3.
Symptom
Check item
CONSULT-III/GST cannot ac-
cess any system.
• CONSULT-III/GST DLC power supply circuit (Terminal 8 and 16) and ground circuit (Terminal 4 and
5)
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-17, "Trouble Diagnosis Flow Chart"
.
