INSPECTION PROCEDURE

If the CONSULT /GST cannot diagnose the system properly, check the following items.

Symptom	Check item
CONSULT /GST cannot access any system.	CONSULT /GST DLC power supply circuit (Terminal 8 and 16) and ground circuit (Terminal 4 and 5).
CONSULT cannot access individual system. (Other systems 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 DLC. (For detailed circuit, refer to wiring diagram for each system.) Open or short circuit CAN communication line. Refer to Trouble Diagnosis Flow Chart .

NOTE:

The DDL1 and DDL2 circuits from DLC pins 6, 7, 12, 13 and 14 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.

For a complete DDL circuit layout and a complete CAN lines layout, refer to appropriate Wiring Diagram.
