Diagnostic Trouble Codes
More about DTCs
Diagnostic Trouble Codes (DTCs) are numerical codes generated by the onboard computer systems in modern vehicles to indicate specific issues or problems with various components of the vehicle. These codes are part of the On-Board Diagnostics (OBD) system, which is designed to help mechanics and technicians quickly identify and diagnose problems with a vehicle.
DTCs help streamline the troubleshooting and repair process, making it easier to pinpoint and fix problems with a vehicle's various systems. They are standardized across the automotive industry, so a code for a specific issue on one car should have the same meaning on another, regardless of the make or model.
