DTC Off Software

DaVinci Ghost is the Windows desktop ECU software from DaVinci Deluxe for working with diagnostic trouble codes (DTCs) in a car, van or truck ECU file. Open the file and the DTC Table Explorer lists the codes with their descriptions; you pick the ones to switch off and they are applied on the bench with the checksum corrected. No token is charged if the file cannot be read.

The DTC Table Explorer

When you open a file, the analysis returns the DTCs it finds with human-readable descriptions, so you are not typing raw hex codes. You choose exactly which codes to switch off; the AUTO DTC switch handles the rest and writes the file back with a corrected checksum and CVN.

Precise, per-code control

Unlike a blanket clear, you decide code by code. Everything you do to that file after the first token is included, so you can review, adjust and re-save the same file for free.

Three steps, one token

  1. Open your ECU file in DaVinci Ghost. The analysis identifies the control unit and shows every solution available for that exact software.
  2. Apply the AUTO DTC switch (and any other available switch). Enable CHK/CVN so the checksum and CVN are corrected on save.
  3. Save the file to your PC. If the file was not tunable, no token was charged.

Questions about DTC off

Can I choose which DTCs to switch off?

Yes. The DTC Table Explorer shows each code with its description and you select the ones you want off; the rest are left untouched.

Does it correct the checksum after DTC off?

Yes. Enable CHK/CVN before saving and the file is written back with a corrected checksum and CVN, at no extra cost.

Which ECUs are supported?

The same broad list as the other solutions: Bosch, Siemens/Continental, Delphi, Denso, Marelli and heavy-duty units on many software versions. The analysis confirms DTC handling for your exact file.
