Check DLC3

CHECK DLC3






HINT: The vehicle uses ISO 9141-2 communication protocol. The terminal arrangement of the DLC3 complies with SAE J1962 and matches the ISO 9141-2 format.




If the result is not as specified, the DLC3 may have a malfunction. Repair or replace the harness and connector.






HINT: Connect the cable of the hand-held tester to the DLC3, turn the ignition switch ON and attempt to use tester. If the screen displays the message UNABLE TO CONNECT TO VEHICLE, there is a problem either with the vehicle or with the tester.

- If communication is normal when the tester is connected to another vehicle, inspect the DLC3 of the original vehicle.
- If communication is still not possible when the tester is connected to another vehicle, the problem is probably in the tester itself.Consult the Service Department listed in the tester's instruction manual.
