DTC OFF & Readiness
DTC OFF: when I select DTC OFF and choose the DTCs, do I have to activate readiness also?
Usually no. You only need readiness if the car must pass an OBD/inspection that checks readiness monitors and those monitors won’t complete normally (often when systems like DPF/EGR/SCR are disabled/removed). Otherwise, DTC OFF alone is enough.
Ok, when do I need to activate readiness?
Only when the car must pass an OBD/inspection that checks readiness monitors, and those monitors won’t complete normally because a system is disabled/removed (commonly DPF/EGR/SCR). Otherwise, don’t enable readiness.
Troubleshooting
After saving, the switches show blue 'ON' again when I reopen the file — is this normal?
- After applying a solution (e.g., DTC OFF / DPF / EGR / AdBlue), you save the file.
- When you reopen the file, some switches appear as blue 'ON' again.
- You assume the modification was not applied successfully.
- This is normal: the interface displays certain switches as 'ON' by default when a file is initially opened.
- This does not mean the modification was reverted. The changes are already embedded in your saved file.
- If you press the same switch a second time, the LOG might not show anything new because the action was already executed during the first save.
- Check the final status in the results area / right-side list: processed modules usually appear as 'OFF' (often in red) when successfully disabled.
- DTCs that are already deleted/processed do not get rewritten as 'new' in the LOG.
- If in doubt, compare 'before/after' using the status area, not just the switch color upon reloading.
- Open the original file, apply the solution, then save.
- Reopen the saved (modified) file.
- Do not rely solely on the blue 'ON' button upon reload (this is just the UI state).
- Check the right-side list/status: already processed items should explicitly show as 'OFF'.
- Confirm the LOG does not add redundant entries if you trigger the same action (since it’s already applied).
- If needed, test on a completely different DTC to see a fresh addition in the LOG.
Note: Use these functions only for legal use and according to local regulations.

Do I risk bricking my ECU?
DaVinci Deluxe expertly alters ECU Dump files while protecting the map structures. However, safely writing (flashing) these files back to the ECU is the user's responsibility and relies on the stability of your workshop flashing tools.
