What You Can Diagnose
TopScan Lite 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:
- Oil reset
- EPB
- SAS
- TPMS
- Battery registration
- Throttle relearn
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 compatible iOS or Android device. Vehicle coverage spans major brands; resets and bi-directional tests are model-dependent.
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
DIYers who already carry a smartphone and want pro-level scans without a dedicated tablet.
Why Choose TOPDON
TopScan Lite is TOPDON's best-value Bluetooth scanner — bi-directional all-system access and AutoAuth at a fraction of wired pro tool prices.
