This function allows you to read Diagnostic Trouble Codes (DTCs) that have caused the Check Engine Light to illuminate, and then clear them.
- From the main menu, select OBD/EOBD.
- The scanner will establish communication with the vehicle.
- Select Read DTC to view current, pending, and permanent codes.
- To clear codes, select Clear DTC. Confirm your choice when prompted. Clearing codes will turn off the Check Engine Light.
7.2 I/M Readiness Status
This function checks the readiness of the emission-related monitoring systems on the vehicle. It's useful for determining if the vehicle is ready for an emissions test.
- From the main menu, select OBD/EOBD.

- Choose to view the data or create a custom data set.
- The screen will display various parameters such as engine RPM, vehicle speed, oxygen sensor readings, fuel system status, and more.
7.4 Freeze Frame Data
When an emission-related fault occurs, the ECU records certain vehicle operating conditions at the time of the fault. This data is called Freeze Frame Data.
- From the main menu, select OBD/EOBD.
- Select Freeze Frame.
- The scanner will display parameters such as engine load, coolant temperature, fuel system status, and vehicle speed at the moment the fault occurred.
7.5 DTC Library Lookup
