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/GST Data Link Connector (DLC) Circuit
INFOID:0000000009652485
INSPECTION PROCEDURE
If the CONSULT/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 access to other systems.
If the GST cannot operate properly, check the circuit based on the information of SAE J1962 and ISO 15031-
3.
