What Does DTC Mean in Diagnostics?

DTC stands for Diagnostic Trouble Code. In the world of diagnostics, DTCs are codes that are stored in a vehicle's computer system when a problem is detected. These codes help technicians identify the specific issue affecting the vehicle's performance.

Diagnostics play a pivotal role in the diesel engine industry for various reasons, including early issue detection.
