FAQ: Frequently asked questions about Vasya Diagnostic
Is it possible to use Vasya Diagnostic on a MacBook?
Officially the program only supports Windows. However, it can be run on macOS via virtual machine (Parallels Desktop or VirtualBox) or Wine (but stability is not guaranteed). For Linux there is also an option with Wine, but there may be problems with the adapter drivers.
Which adapter is better to choose for working with the program?
Suitable for most tasks ELM327 chip based FT232RL (avoid cheap Chinese clones). For in-depth diagnostics Nissan/Renault better use K-Line adapter (eg Vag-Com KKL or Nissan Consult Cable). For new models (with CAN FD) may be required VGate iCar2.
Is it possible to reset the service interval using Vasya Diagnostic?
Yes, the program allows you to reset the service interval for most supported models. To do this you need to go to the section Service functions, select Maintenance reset and follow the instructions. However, on some vehicles (for example, Nissan X-Trail T32) this requires additional software.

This is a common problem due to the fact that some blocks (for example, ABS or Airbag) use separate protocols. Try:
- Switch the protocol in the program settings.
- Use a different adapter (for example, K-Line instead of ELM327).
- Check the power supply to the unit (sometimes it is necessary to turn the ignition on to the 2nd position).

Using it for commercial purposes (for example, in a car service) may be considered a violation of intellectual property rights Nissan/Renault.
