C. Clear Fault Code
This function enables you to erase the codes from the vehicle after reading the retrieved codes from the vehicle and
certain repairs have been carried out. Before performing this function, make 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.
On the diagnostic function selection screen, tap
Clear Fault Code
, the following screen will appear.
Tap
YES
, 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.
