DLC3 INSPECTION
The vehicle's ECM uses 1509141-2 for communication. The terminal arrangement of DLC3 complies with SAE J1962 and matches the ISO9141-2 format.

HINT: If your display shows "UNABLE TO CONNECT TO VEHICLE" when you have connected the cable of the OBDII 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 it the tool itself, so consult the Service Department listed in the tool's instruction manual.
