CONSULT-III/GST Data Link Connector (DLC) Circuit

 
 INSPECTION PROCEDURE

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

Symptom
Check item
CONSULT-III/GST cannot access any system.
  • CONSULT-III/GST DLC power supply circuit (Terminal 8 and 16) and ground circuit (Terminal 4 and 5)
CONSULT-III 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-III 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 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 systems.
If the GST cannot operate properly, check the circuit based on the information of SAE J1962 and ISO 15031-3.
