CHECK DLC3







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

HINT: If the screen displays a communication error message after the cable of the intelligent tester is connected to the DLC3, engine switch is turned on (IG) and used the intelligent tester is used, the problem may be on the vehicle side or tester side.
- If communication is normal when the tester is connected to another vehicle, inspect the DLC3 of the original vehicle.
- If communication is still impossible 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.
