how to turn off engine light "hptuner"
#2
1. Open your tune.
2. Go into Engine Diag
3. Select the DTC's tab
4. Find the DTC and set it to no light or disable it entirely.
5. write the tune to the car
But for the love of god... don't just disable a DTC (or all DTCs) just because you don't want the light to come on! There are only a few reasons to disable a DTC, the most common reason is after installing headers without CATs or rear O2's.
