Scan Tool Testing and Procedures

If the scan tool Does Not Power Up;

Check for loose cable connections or a bad cable. Check the vehicle battery voltage (data link connector cavity 16).

If all connections are proper between scan tool and the vehicle, and the vehicle battery is fully charged, an inoperative scan tool may be the result or faulty cable or vehicle wiring.
