What the SEC system covers

SEC 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.
