## Diagnosis & Errors

Diagnosis & Errors gives access to diagnostic information for the selected vehicle.

Available error messages, warning codes, and other technical details appear in this section. Important warnings are shown so users can see whether the vehicle may need attention.

This information provides users a better basis for deciding what to do next. Depending on the issue, the next step may be checking the vehicle, reporting the problem, contacting support, or arranging service.

Having diagnostic information in the app makes technical issues easier to notice before they affect the next trip.
