## Summary description

Konnwei KW850 is an OBD2 diagnostic scanner for passenger vehicles that reads and clears diagnostic trouble codes (DTC), displays live sensor data and supports standard OBD-II functions. Designed for mechanics and car owners, it helps identify engine and emission-related faults, perform basic diagnostics, and verify repairs using real-time data and error code information.

## Long description

The Konnwei KW850 OBD2 diagnostic scanner is a compact vehicle code reader designed for passenger cars that support the OBD-II standard. It reads and clears diagnostic trouble codes (DTC), displays live sensor data, and provides standard OBD-II functions to help identify engine and emissions-related faults. The device is intended for use by mechanics, DIY car owners and technicians who need a straightforward tool for basic diagnostics and verification of repairs.
Advantages
The KW850 offers clear code reading and one-touch code clearing together with live data streaming from engine sensors, helping to confirm the presence of faults and to check repair results. Its compact design and straightforward interface reduce setup time and make it easy to connect to the vehicle’s OBD-II port. The scanner supports common OBD-II modes, presenting diagnostic information in a format suitable for quick troubleshooting and basic service checks.
Suitable for
 Reading and clearing generic and manufacturer-specific engine fault codes
 Viewing live sensor data such as RPM, vehicle speed, coolant temperature and fuel system status
 Quick verification of repairs after fault correction
 Routine emission-related checks and simple pre-inspection diagnostics
When it may not be suitable
The KW850 is designed for basic OBD-II diagnostics and does not replace dealer-level diagnostic tools. It does not offer advanced system programming, module coding, or deep manufacturer-specific functions that are required for complex repairs or advanced calibration tasks. For diagnostic needs involving ABS, airbag module configuration, transmission adaptations or body control module programming, a factory-level or dedicated professional scanner is recommended.
Key specifications
 Supported protocol: Standard OBD-II communication (multiple OBD-II protocols)
 Functions: Read/erase diagnostic trouble codes, display live data, freeze frame, monitor status
 Display: Built-in screen for code and data readout
 Connectivity: Direct wired connection to vehicle OBD-II port
 Power: Powered from the vehicle OBD-II port (no separate battery required)
 Compatibility: Passenger vehicles compliant with OBD-II standard
How to use
Turn the vehicle ignition to the accessory or run position, then plug the KW850 into the vehicle’s OBD-II port. The device will power up automatically from the vehicle and begin communicating with the vehicle ECU. Use the on-screen menu to read codes, view live data streams or clear stored DTCs. After reading codes, consult the displayed code definitions to identify the subsystem involved and plan necessary checks or repairs. Always clear codes only after completing repairs and verifying that the underlying issue has been resolved.
What to consider before purchase
 Confirm that the vehicle supports the OBD-II standard and locate the OBD-II port
 Check whether advanced manufacturer-specific functions are required for your diagnostic needs
 Ensure you need a wired, handset-style scanner rather than a Bluetooth or mobile app-based solution
Usage recommendations
Use the KW850 for routine engine and emissions diagnostics, live sensor checks during troubleshooting, and for verifying repairs. For persistent or complex faults, combine KW850 data with service manuals and professional diagnostic tools to ensure accurate fault isolation and repair.
