# Diagnostic Systems

> To support our System Status endpoint, reference the below list of unified systems.

The [System Status](https://smartcar.com/docs/api-reference/get-system-status) endpoint returns a list of systems reported by any given vehicle, as well as their current state which may be "OK" or "ALERT".
