UTH: Under The Hood

Under The Hood keeps your Garage, vehicle records, supported scanner information, and automotive guidance in one place.

Add a vehicle with guided Year, Make, Model, Trim, and Engine choices, or use the custom and swapped-vehicle path. Record maintenance, build parts, projects, fuel, and useful findings. Signed-in Garage sync covers only owner-scoped vehicles, maintenance records, build parts, and build projects when the service is available.

Connect a supported UTH Bluetooth scanner to view diagnostic codes and live readings supported by the scanner and vehicle. Missing data is not a zero, and an incomplete scan is not proof that no faults exist. Generic and third-party ELM adapters are best-effort and unsupported.

Ask Nia Basic an automotive question using your selected vehicle and available scanner context, or choose the offline reference. Hosted Nia Basic requires a signed-in account and internet connection. Answers may be incomplete or wrong; confirm important specifications, repairs, and safety decisions with manufacturer information and a qualified professional.

UTH remains useful without a scanner. It does not guarantee a diagnosis, repair, or safe-to-drive decision. Never interact with the app or scanner while driving. Community, public sharing, Nia Pro subscriptions, and live payments are not part of this release.
