KW850 OBD2 CAN BUS Code Reader Car Engine Fault Code Detector Scanner with TFT Display and One-Click I/M Readiness Key
The KONNWEI KW850 OBDII/EOBD scanner is designed for technicians and car owners who need a reliable tool to diagnose engine faults quickly. When the check engine light comes on, this device reads the stored fault codes from the powertrain control module (PCM) and helps pinpoint the problem area. Supporting all 10 OBDII test modes, it covers generic (P0, P2, P3, U0) and manufacturer-specific codes (P1, P3, U1) across US, European, and Asian vehicles from 1996 onward.
Features and Construction
The KW850 combines practical functions with straightforward controls, making it suitable for both professional use and home mechanics.
One-Click I/M Readiness Key
A patented button quickly checks the vehicle's I/M readiness status for emissions testing, saving time during inspections. This feature helps identify which monitors are ready or not, assisting with passing smog checks.
Display and Audio
The large backlit LCD screen shows DTC definitions, live data, and freeze frame information in clear text. A built-in speaker provides audio feedback, and the TFT colour display enhances readability in different lighting conditions.
Data Recording and Graphing
Live PCM datastream can be read, stored, and played back for later analysis. The scanner also graphs live O2 sensor test data on vehicles from 1996 and newer, helping monitor sensor performance over time.
Uses and Placement
This scanner is suitable for a range of diagnostic tasks, from quick code reads to in-depth data analysis.
Professional Diagnostic Work
Works on multiple protocols including CAN and all other current OBDII standards. Retrieves vehicle information such as VIN, CIN, and CVN. The built-in OBDII DTC lookup library and thousands of troubleshooter code tips help mechanics reduce diagnosis and repair time.
Everyday Home Use
For car owners, the KW850 can turn off the check engine light, clear codes, and reset monitors after repairs. The memory/battery backup allows off-vehicle review of previously recorded data, so you can analyse readings without the car running.
Benefits and Buying Value
The KW850 offers a balance of power and affordability, with features that streamline common diagnostic tasks.
Reuse and Low Maintenance
The device is software-upgradeable via internet, keeping it current with evolving OBDII protocols. No consumables are needed beyond the USB connection for updates or data printing. The protective nylon case helps store the scanner safely between uses.
Why Choose This Product
With support for 8 languages (English, French, German, Dutch, Spanish, Russian, Portuguese, Italian) and the ability to print data via PC, this scanner suits multi-lingual workshops. Its combination of live data graphing, freeze frame data, and pending code identification gives a comprehensive view of engine health without requiring an expensive professional tool.
