Elon Musk announced plans to "open source" the Model S and Model X, building on the framework set by Tesla's original Roadster release. As production for the S and X comes to an end, this initiative creates an opportunity to share technical documentation, diagnostic software, and board files with the broader electric vehicle community.

Tesla's previous Roadster release provided diagnostic tools, minor board outputs, and CAN databases that give independent mechanics and enthusiasts practical resources to support and maintain these vehicles. Extending these diagnostic packages and technical files to the flagship Model S and Model X platforms offers a valuable foundation for independent repair shops and engineers looking to keep these legacy electric vehicles running for years to come.
