Toyota C-HR diagnostics
Toyota C-HR (2016–2026): free AI diagnosis by symptoms, fault codes or a dashboard photo — plus OBD-II reading right in the browser.
What usually goes wrong on the Toyota C-HR
- Бензиновый 1.2 турбо (8NR-FTS) с непосредственным впрыском зарастает нагаром на впускных клапанах — неровный холостой ход и троение к 80-100 тыс. км.
- Слабая 12-вольтовая АКБ гибрида разряжается при коротких поездках и долгих простоях — машина не переходит в режим Ready.
These are the model's typical weak points, not a verdict on your particular car: the AI keeps them in mind, but the diagnosis comes from your symptoms and your codes.

Describe the problem
Tell the AI chat what your Toyota C-HR 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.

Describe what's happening or paste the fault codes — the AI will narrow down the cause and tell you what to check first.
Start diagnosisWhat can be read from this car
Through the OBD-II port on your Toyota C-HR 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.
Hybrid: keeping an eye on the battery
The Toyota C-HR is a hybrid, and there's usually one big question about it: how much life is left in the high-voltage battery. The program reads the voltage of every module in it, works out the spread between them and gives a verdict — plain OBD-II doesn't hand over this data.
For a deeper scan of your Toyota C-HR — all modules, live data, freeze frames — use the free Diagnost program for Windows or macOS with an ELM327 adapter.
