What You Can Diagnose
TopScan Master 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:
- Full TopScan reset suite
- Advanced bi-directional tests
- EPB and SAS 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
Requires recent iOS/Android device with Bluetooth. Confirm Master-tier functions for your vehicles.
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.
