Lexus UX diagnostics
Lexus UX (2018–2026): free AI diagnosis by symptoms, fault codes or a dashboard photo — plus OBD-II reading right in the browser.
Describe the problem
Tell the AI chat what your Lexus UX is doing — noises, warning lights, behavior. It knows the model's typical weak points and asks the right follow-up questions.
Read the codes
Plug an ELM327 adapter (over USB or Bluetooth LE) into the OBD-II port and read fault codes right in the browser on the Connect adapter page — no software to install.
Get a verdict
The AI ranks the likely causes, tells you what to check first and whether it's safe to keep driving.

Start diagnosisWhat can be read from this car
Through the OBD-II port on your Lexus UX you can read engine fault codes, live sensors, readiness monitors and a freeze frame — with an ELM327 adapter, including right in the browser. If the car has a CAN bus (roughly 2008 and newer), the program additionally polls the remaining modules:
- ABS / VSC
- Подушки безопасности
- Электроусилитель руля
- Приборная панель
- Климат-контроль
- Гибридная система
The list of modules depends on the trim and options: the program shows the ones that actually answered.
For a deeper scan of your Lexus UX — all modules, live data, freeze frames — use the free Diagnost program for Windows or macOS with an ELM327 adapter.
