⚡ At a Glance
- • Diagnostic Coverage: Reads engine, transmission, ABS, steering, safety, infotainment and other systems, plus full OBDII modes and live data
- • Best for: Mechanics, advanced DIYers and garage owners who need quick fault diagnosis and repair guidance
- • Not ideal for: Users who require advanced system resets beyond reading and clearing codes
Wireless BT5.0 connects to iOS and Android apps for full-system quick scans. Live data, fault definitions and readiness checks help troubleshoot and prepare a car for MOT.
Quicker, clearer fault diagnosis – with All System Diagnosis and fault code library
All System Quick Scan reads fault codes across modules, displays severity, freeze frame and offers fault cause descriptions with repair suggestions. A built-in fault code definitions library maps codes to likely causes and recommended actions.
Faster identification of which issues need immediate attention keeps workshop time focused. Clear causes and suggested fixes reduce time spent guessing during repairs.
Prepare for MOT and clear emission checks – thanks to full OBDII test modes and I/M readiness
Full OBDII test modes include one-click I/M readiness, EVAP tests and retrieval of emission-related DTCs and freeze-frame data. Readiness status shows whether emission monitors are set for MOT verification.
Home and workshop users can check readiness before an MOT and address emission faults early. Catching issues beforehand avoids unnecessary test failures and rebookings.
Monitor performance and receive real-time warnings – with Performance Test, Trip Recorder and Fault Warning
Performance Test and Trip (Analyse) log acceleration, fuel efficiency, coolant temperature, engine speed and voltage, while fault warning pushes alerts to a connected smart device when codes appear or parameters exceed thresholds.
Track driving data for performance tuning or economy checks and get immediate alerts if dangerous temperatures or faults occur. Useful for performance-minded drivers and fleet monitoring.
