CONSULT-III CHECKING SYSTEM
*1: With Intelligent Key System.
*2: With automatic transmission.
*3: Without Intelligent Key System.
CONSULT-III Data Link Connector (DLC) CircuitINFOID:0000000001691474
INSPECTION PROCEDURE
If the CONSULT-III cannot diagnose the system properly, check the following items.
NOTE:
The CAN and DDL2 circuits from DLC pins 6, 7 and 14 may be connected to more than one system. A short in
any circuit connected to a control unit in one system may affect CONSULT-III access to other systems.
Symptom Check item
CONSULT-III cannot access
any system. CONSULT-III DLC power supply circuit (Terminal 8) and ground circuit (Terminal 4)
CONSULT-III cannot access in-
dividual system. (Other sys-
tems 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 LAN-22, "
Trouble Diagnosis Flow Chart".
