  3. Connect the cable of the intelligent tester to the DLC3, turn the engine switch on (IG) and attempt to use the intelligent tester. If the screen displays a communication error message, a problem exists in the vehicle or in the tester.

    1. If communication is normal when the tool is connected to another vehicle, inspect the DLC3 on the original vehicle.
    2. If communication is still impossible when the tool is connected to another vehicle, the problem is probably in the tool itself. Consult the Service Department listed in the tool instruction manual.
