V311
Broad-compatibility OBD-II/EOBD scanner with waveform playback
V311 supports 9 standard OBD-II/EOBD protocols for wider vehicle coverage, while combining diagnostics, live data, waveform display, and storage/playback. Its wide voltage protection design adds stability across different vehicle electrical environments.
OBD-II/EOBD Protocol Support
Supports 9 standard OBD-II/EOBD protocols—helps ensure broad vehicle compatibility for stable diagnostics coverage across mixed driver fleets.
Diagnostics & Live Data
Combine core diagnostics with real-time data stream viewing to validate issues live and improve driver support outcomes.
Waveform + Storage/Playback
Display live data in waveform form and store sessions for playback—useful for spotting patterns and reviewing intermittent issues after the drive.
Comprehensive Diagnostic Data Access
Provides access to essential OBD diagnostic functions together with a wide range of live vehicle parameters, including RPM, load value, coolant temperature, fuel system status, fuel trim, speed, manifold pressure, intake air temperature, ignition timing, air flow, and throttle position.
