SERVICE INFORMATION FOR ELECTRICAL INCIDENT
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 ligh t up the
lamp.
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. Cont rol 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 u p the lamp.
Control Units and Electrical PartsINFOID:0000000001325673
PRECAUTIONS
 Never reverse polarity of battery terminals.
 Install only parts specified for a vehicle.
 Before replacing the control unit, check the input and output and functions of the component parts.
 Do not apply excessive force when disconnecting a connector.
 Do not apply excessive shock to the control unit by dropping or hit- ting it.
 Be careful to prevent condensation in the control unit due to rapid temperature changes and do not let water or rain get on it. If water
is found in the control unit, dry it fully and then install it in the vehi-
cle.
 Be careful not to let oil to get on the control unit connector.
 Avoid cleaning the control unit with volatile oil.
 Do not disassemble the control unit, and do not remove the upper and lower covers.

CONSULT-III/GST Data Link Connector (DLC) CircuitINFOID:0000000001572195
INSPECTION PROCEDURE
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-14, "
Trouble Diagnosis Flow Chart".

RETAINED PWR This test is able to supply RAP signal (powe
r) from BCM (body control module) to power window
system and power sunroof system (if equipped). Those systems can be operated when turning on
“RETAINED PWR” on CONSULT-III screen even if the ignition switch is turned OFF.
NOTE:
During this test, CONSULT-III can be operated with ignition switch in “OFF” position. “RETAINED
PWR” should be turned “ON” or “OFF” on CONSULT-III screen when ignition switch is ON. Then
turn ignition switch OFF to check retained power operation. CONSULT-III might be stuck if “RE-
TAINED PWR” is turned to “ON” or “OFF” on CONSULT-III screen when ignition switch is OFF.
Work item Description
RETAINED PWR Rap signal’s power supply period can be changed by mode setting. Selects rap signal’s power sup-
ply period between three steps
