Where would you obtain any fault code date from?

Fault code data can typically be obtained from the vehicle's onboard diagnostic system (OBD-II) using a code reader or scan tool. Many automotive repair shops and dealerships also have access to specialized diagnostic equipment that can retrieve fault codes. Additionally, some vehicle manufacturers provide online resources or software that allow users to access fault codes. For home mechanics, there are various mobile apps that can connect to the vehicle's OBD-II port via Bluetooth to display fault codes.
