Info

What the UI system covers

User Interface alerts belong to Tesla's proprietary diagnostic alert system and are grouped under the network category.

Read all active alerts together instead of diagnosing a single code in isolation.
Check recent service, firmware updates, and low-voltage battery condition.
Use Tesla Service or a qualified EV technician for safety-critical systems.
