CONSULT-II Data Link Connector (DLC) Circuit
INSPECTION PROCEDURE
If the CONSULT-II cannot diagnose the system properly, check the above 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-II access to other systems.
Ground Inspection
Ground Inspection
Ground connections are very important to the proper operation of electrical and electronic circuits. Ground connections are often exposed to moisture,
dirt and other corrosive elements. The corrosion (rust) can become an unwanted resistance. This unwanted resistance can change the way a circuit works.
