What is a DTC? How should I react when my vehicle showing DTCs?

The Diagnostic Trouble Codes (DTC) are codes that the car's OBD system uses to notify you about an issue. Each code corresponds to a fault detected in the car. If there's a DTC that happened with your vehicle, you should be able to retrieve it from the "Asset Details". Please refer to the below webpage for trouble codes and contact your mechanics for troubleshooting
