Check DLC3

CHECK DLC3







The vehicle's ECM uses ISO 9141-2 for communication.
The terminal arrangement of the DLC3 complies with SAE J1962 and matches the ISO 9141-2 format.

HINT: If the display shows "UNABLE TO CONNECT TO VEHICLE" when the cable of the intelligent tester is connected to the DLC3, the ignition switch is turned ON and the intelligent tester is operated, there is a problem either on the vehicle side or tester side.

- If communication is possible when the tester is connected to another vehicle, inspect DLC3 on the original vehicle.
- If communication still not possible when the tester is connected to another vehicle, the problem is probably in the tester itself, so consult the service department listed in the tester's instruction manual.
