Autel TCAN003 Tesla Diagnostic Adapter Cable

Autel TCAN003 is a diagnostic adapter cable designed to connect compatible Autel diagnostic tools to Tesla vehicle CAN diagnostic connections.

TCAN003 combines applications previously covered by the TCAN001 and TCAN002 cables into a single adapter and provides a standard 16-pin OBDII connection for the diagnostic tool. This simplifies Tesla diagnostics by reducing the need for multiple separate adapter cables.

The cable supports compatible Tesla Model S, Model X, Model Y, and Model 3 vehicles. Depending on the vehicle, connection is made through the Tesla X437 port or the vehicle's CAN diagnostic connector.

Features

• Tesla diagnostic adapter — Connects a compatible Autel diagnostic tool to the Tesla vehicle CAN network.
• 16-pin OBDII connection — Standard OBDII interface for compatible diagnostic equipment.
• Replaces TCAN001 and TCAN002 applications — One cable covers multiple applications previously requiring separate Tesla adapters.
• Model S / X support — Connects through the Tesla X437 diagnostic port on compatible vehicles.
• Model 3 / Y support — Connects through the vehicle CAN diagnostic connector on supported models.
• Direct diagnostic connection — Enables Tesla diagnostics with compatible Autel tools without additional software when Tesla diagnostic software is already supported by the tool.
• Professional workshop use — Suitable for general repair workshops, EV specialists, and Tesla diagnostic work.
