What is a DTC Code?
A Diagnostic Trouble Code (DTC) will appear when your vehicle’s on-board computer detects an issue. The DTC is a code describing the issue that resulted in the check engine light turning on. You can see DTCs in the Dashboard (next to the "ISSUE" icon), or in the Pending tab of the Service screen. Tapping the DTC provides more details including the severity and potential fixes. Based on this information, you can decide the course of action including visiting a garage. You can find nearby garages from the Service screen.
