Check DLC3

CHECK DLC3












HINT: The vehicle uses ISO 15765- 4 communication protocol. The terminal arrangement of the DLC3 complies with SAE J1962 and matches the ISO 15765- 4 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 intelligent tester to the DLC3, turn the engine switch on (IG) and attempt to use the tester. If the display indicates that a communication error has occurred, 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 may be in the tester itself.Consult the Service Department listed in the tester's instruction manual.
