CONSULT-III CHECKING SYSTEM
CONSULT-III Data Link Connector (DLC) Circuit
If the CONSULT-III cannot diagnose the system properly, check the following items.
The DDL2 circuits and CAN communication lines from DLC pins 6, 7 and 14 may be connected to more than one system. A short in a DDL circuit or CAN lines connected to a control unit in one system may affect CONSULT-III access to other systems. For a complete DDL circuit layout, refer to See: CONSULT-III Checking System Wiring Diagram\Coupe or See: CONSULT-III Checking System Wiring Diagram\Sedan. For a complete CAN line layout, refer to See: Diagrams\Electrical\Computers and Control Systems\Information Bus.
