The BT200 MAX connects wirelessly to phones and tablets to read trouble codes, view live sensor data and perform active tests. It pairs ELM327 compatibility with a native AI assistant inside the dollarfix app for guided fault interpretation, while also offering bi-directional control, FCA auto-auth (SGW), CANFD protocol support and lifetime updates. Designed for DIYers, enthusiasts and independent technicians, the unit balances broad third-party app compatibility with advanced manufacturer-level functions.

How does the BT200 MAX help quickly identify vehicle problems?

The device reads standard and manufacturer-specific OBD2 trouble codes and displays live data streams so you can spot anomalies fast. When used in the dollarfix app, an AI avatar explains fault codes in plain language and suggests troubleshooting steps, helping non-experts interpret results without guessing.

• Reads generic and proprietary diagnostic trouble codes (DTCs).
• Shows live sensor values like RPM, coolant temperature and fuel trim.
• AI-generated code analysis and step-by-step suggestions in the app.
• Data logging and exportable reports for later review or repair shops.

Will this scanner work with my favorite diagnostic apps and software?

Yes — the BT200 MAX supports ELM327 command compatibility, letting it operate with many popular apps such as Torque and Car Scanner. You can switch to "ELM327 Mode" when needed, turning the unit into a universal scanner for third-party tools while retaining its native advanced features in the dollarfix environment.

• EML327/ELM327 compatibility for wide app support.
• Native dollarfix app for AI assistance and extended diagnostics.
• Works with iOS and Android devices over Bluetooth.
