Diagnostic functions:

The Topdon TopScan Master performs a full system diagnosis on all electronic control units present in the vehicle, such as the engine, transmission, ABS, airbags, and body modules.

• Read and clear fault codes: Reads and clears fault codes (DTCs) from all available vehicle systems.
• Live data: Displays real-time data from sensors and components in various views, such as numeric and graphical. This allows data streams to be analyzed to identify the cause of problems.
• Actuator testing (Bidirectional control): Directly controls components such as relays, injectors, fans, and valves to check functionality without physical disassembly.
• I/M Readiness: Checks the status of emission-related systems to determine if the vehicle is ready for an emissions test.
