What is an OBD2 Scanner?

Simply put, an OBD2 scanner is a device built to connect to the onboard digital system of a car through the OBD2 port.

The OBD2 scanners stand for Onboarding Diagnostics; the device is an example of a car diagnostic scanner. The scanner gains access to the car's system and documents the readings.

Diagnostic Trouble Code (DTC)

The DTC is a code that serves as a language that explains what exactly is wrong with a car.

It is similar to how computers communicate in binary, leaving the programmer to interpret the code.

The DTC codes offer insight and can range from simple number codes to more complicated data depending on the complexity of the car diagnostic scanner.

Foxwell live data OBD2 scanners have models that range from small or compact cars to more extensive or sophisticated car systems.

However, the importance of a car diagnostic scanner like the OBD2 scanner goes above and beyond.
