CONSULT-III/GST Data Link Connector (DLC) Circuit
INFOID:0000000001679209
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.
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.
