The Tesla 26-Pin Diagnostic Adapter is a precision-engineered harness designed to bridge the gap between Tesla’s proprietary internal data port and standard OBD2 diagnostic equipment. Since Tesla Model 3 and Model Y vehicles do not come equipped with a traditional under-dash OBD2 port, this cable is essential for owners and technicians who need to access real-time vehicle data.

This adapter allows you to connect a compatible Bluetooth or Wired OBD2 scanner directly to the vehicle's CAN bus. By doing so, you can unlock a wealth of information not visible on the main Tesla touchscreen, including detailed battery health, individual cell voltages, motor temperatures, and drivetrain performance. Built with high-quality tin-plated copper wire and durable PA66 housing, this cable ensures a secure, interference-free connection even during long-term data logging.

Key Features & Technical Specifications

• Precision 26-Pin Connector: Custom-designed to fit the Tesla-specific diagnostic port located at the rear of the center console.

• Standard 16-Pin OBD2 Interface: Translates Tesla data into a format compatible with standard diagnostic tools.

• High-Speed Data Flow: Supports full CAN bus communication with no signal delay or loss.

• Durability: Automotive-grade insulation rated for temperatures from -40°C to 120°C.

• Plug-and-Play: No cutting or splicing of factory wires is required; the installation is completely non-destructive.

• Universal Software Support: Fully compatible with popular apps like Scan My Tesla (Android) and tesLAX (iOS).

Global Compatibility & Important Note

This device is a Global Edition and is compatible with Tesla Model 3 and Model Y vehicles in any country worldwide.
