Check DLC3

Check the DLC3







The main body ECU uses ISO 9141-2 for communication. The terminal arrangement of the DLC3 complies with SAE J1962 and matches the ISO 9141-2 format.

Verify the conditions listed in the table:

HINT: If the intelligent tester display shows UNABLE TO CONNECT TO VEHICLE when the cable of the intelligent tester is connected to the DLC3, the ignition switch is turned to the ON position and the tester is operated, there is a problem on either the vehicle side or the tester side.
- If communication is normal when the tester is connected to another vehicle, inspect the 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 tester itself, so consult the Service Department listed in the tester's instruction manual.
