4.2. Clearing Fault Codes

Important: Ensure that any underlying faults have been repaired before clearing codes. Clearing codes without addressing the issue will result in the fault light reappearing.

1. After reading codes, navigate to the "Clear Codes" option in the menu.
2. Confirm your selection when prompted.
3. The scanner will erase the DTCs, and the engine fault light should turn off.

4.3. Other Functions
