Without a reliable code reader, diagnosing and fixing car problems can be a time-consuming and expensive process.

What is OBD II? OBD II (On-Board Diagnostics II) is a standardized system that monitors various components of your vehicle, including the engine, transmission, and emissions system. It was mandated in the United States for all cars and light trucks manufactured after 1996.
What is CAN? CAN (Controller Area Network) is a communication protocol that allows different electronic control units (ECUs) in your vehicle to communicate with each other. It’s a more advanced and efficient system than the older OBD I standard.
