Check DLC3

CHECK DLC3










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

HINT: If the screen displays UNABLE TO CONNECT TO VEHICLE after you have connected the cable of the intelligent tester to the DLC3, turned the ignition switch ON and used the intelligent tester, there is a problem 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, so consult the Service Department listed in the tester's manual.
