- Engine

For example, you can test:
- Cooling fans

- Actuators
without replacing parts unnecessarily.
ECU Coding
THINKDIAG also supports ECU coding for selected vehicle brands.
This feature can help with:
- Component replacement

Support varies depending on the vehicle manufacturer and model.
Maintenance Functions
The scanner includes more than 15 maintenance functions, such as:
- Oil Reset
- ABS Bleeding
- Injector Coding
- TPMS Reset
- DPF Regeneration
- BMS Reset
- SAS Reset

- Key Coding
For many users, these functions can save significant maintenance costs over time.
