What is a fault code reader?
A fault code reader is an instrument used to read and diagnose fault codes in a car.

How does a fault code reader work?
A fault code reader works by communicating with the car's computer, which monitors the car's various systems. When a problem is detected, a fault code is registered. When you connect your fault code reader, it can retrieve these codes and translate them into either language that a user can understand or into technical terms for mechanics.
