Diagnostics is reading the fault code memory of your vehicle. This helps you to detect errors before you damage your vehicle. You can also find out the reason for an engine light.
How it works:
In your Carly app, OBD diagnostics is already available with the lite version. Here we only read out generic error codes. OBD scans usually only read engine and sometimes transmission ECUs.
If you upgrade the app to full version, you can run advanced diagnostics on manufacturer level for as many times as you want. In the full version, you can find the diagnostics result directly inside the app.
