## Diagnosis & Errors
Diagnosis and Errors provides technical information for a vehicle.
Depending on the available vehicle data, this section may include warning messages, error information, tire pressure data, or other diagnostic details.
The information helps users identify technical issues earlier. If a warning or error appears, users can check whether the vehicle needs attention and decide what should happen next.
This may include checking the vehicle, reporting the issue, arranging service, or monitoring the situation further.
Having diagnostic information inside Fleets makes technical issues easier to notice because they are visible in the same environment where the vehicle is managed.
