Diagnostic functions:

The Topdon TopScan Master performs comprehensive system diagnostics on all available electronic control units in the vehicle, such as engine, transmission, ABS, airbags and body modules.

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

Service and maintenance functions:

The device supports over 25 service and maintenance functions. The availability of specific functions may vary by vehicle make, model and year of manufacture.

Engine and drivetrain:

• Reset service interval: Resets the service reminder for oil changes and maintenance intervals.
• Electronic throttle body learning: Recalibrates the baseline values of the electronic throttle body after cleaning or replacement.
• Injector coding: Programmes the unique codes of new injectors into the engine control unit (ECU) for precise fuel injection.
