Data Link Connector (DLC3) Terminal Identification
Reference
DATA LINK CONNECTOR 3 (DLC3) INSPECTION
The vehicle's ECM uses the ISO 9141-2 communication protocol for communication. The terminal arrangement of DLC3 complies with SAE
J1962 and matches the ISO 9141-2 format.
HINT: If your display shows "UNABLE TO CONNECT TO VEHICLE" when you have connected the cable of the OBD II scan tool or
TOYOTA hand-held tester to DLC3, turned the ignition switch ON and operated the scan tool, there is a problem on the vehicle side or tool side.
(1) If communication is normal when the tool is connected to another vehicle, inspect DLC3 on the original vehicle.
(2) If communication is still not possible when the tool is connected to another vehicle, the problem is probably in the tool itself, so consult the
Service Department listed in the tool's instruction manual.
