Fault Code

A fault code is a diagnostic indicator generated by a vehicle's onboard computer when it detects an issue within the system, such as engine problems or sensor malfunctions. It helps technicians identify where and what the problem is, enabling accurate and efficient repairs. These codes are stored in the vehicle’s computer and can be read using specialized tools, providing a specific reference that guides maintenance without needing to diagnose the problem manually. Fault codes streamline the troubleshooting process, saving time and ensuring issues are addressed correctly.
