HINT:
If the display shows "UNABLE TO CONNECT TO VEHICLE" when the cable of the intelligent tester is connected to DLC3, the ignition switch is turned ON and the intelligent tester is operated, there is a problem either on the vehicle side or the tester side.
- If communication is normal when the tester is connected to another vehicle, inspect DLC3 on the original vehicle.
- If communication does not function 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 instruction manual.
