Check the DLC3

CHECK THE DLC3.







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

HINT: If the display shows "UNABLE TO CONNECT TO VEHICLE" as connecting the hand-held tester to the DLC3 and turn the ignition switch ON, there is a problem either on the vehicle or on the tool.

- If communication is normal when the tool is connected to another vehicle, inspect DLC3 on the original vehicle.
- 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.
