Overview
The TOPDON AD900BT is a flagship-class bi-directional scanner with advanced coding, key programming on supported models, and comprehensive active-test libraries.
Built for technicians who have outgrown mid-tier tools and need deeper ECU routines, TPMS functions, and module programming on supported platforms.
Coverage: Full-system pro. Connectivity: Bluetooth + Wi-Fi. Updates: Lifetime free.
Key Features
- Deep bi-directional diagnostics and active tests
- Advanced ECU coding and adaptations
- Key programming on supported vehicles
- TPMS and full service reset suite
- Wireless connectivity and free updates
What You Can Diagnose
AD900BT helps you identify root causes faster by reading fault codes, live sensor values, and module status across the systems it supports:
- All major ECU modules with bi-directional active tests
- Fuel pump, fan, injector, and actuator command tests
- EPB retraction, caliper service, and brake routines
- Adaptation values, coding, and relearn procedures
- Module communication and network topology faults
Service & Maintenance Functions
Beyond reading codes, this scanner runs guided service routines that save money on dealer labor. Available functions depend on your vehicle make, model, and year:
- Complete reset library
- ECU coding
- Key programming (supported)
- Active tests
- TPMS routines
How to Use This Tool
Connect via USB, WiFi, or Bluetooth depending on your model. Run a full vehicle scan, then drill into individual modules for active tests — command a fuel pump, cycle an EPB motor, or run an injector balance test. Topology views show which modules are online and help trace communication faults across the vehicle network.
Vehicle Compatibility
Premium functions are highly vehicle-specific. Always confirm your make, model, and year against TOPDON coverage before ordering.
Always verify that your exact year, make, model, and engine combination is supported before purchase — especially for service resets, bi-directional tests, and brand-specific modules. OBD2 port location is typically under the driver-side dashboard on U.S. vehicles from 1996 onward.
Who Should Buy This
Professional technicians and advanced DIYers requiring coding and programming beyond standard bi-directional tests.
Why Choose TOPDON
