After reading the retrieved codes from the vehicle and certain repairs have been
carried out, you can use this function to erase the codes from the vehicle. Before
performing this function, please be sure the vehicle's ignition key is in the ON
position with the engine off.
Clearing DTCs does not fix the problem(s) that caused the code(s) to be set. If
proper repairs to correct the problem that caused the code(s) to be set are not
made, the code(s) will appear again and the check engine light will illuminate as
soon as the problem that cause the DTC to set manifests itself.
Tap "Clear Trouble Code" in function menu, the system will automatically delete
the currently existing trouble code.
Note: After clearing, you should retrieve trouble codes once more or turn ignition
on and retrieve codes again. If there are still some trouble codes in the system, please
troubleshoot the code using a factory diagnosis guide, then clear the code and recheck.
