KONNWEI KW850 Professional OBD2 Diagnostic Scanner
The KONNWEI KW850 OBD2 Scanner is a premium, commercial-grade automotive diagnostic tool engineered for fast engine system troubleshooting, error code clearing, and real-time battery health monitoring. Powered by optimized software algorithms, this scanner processes vehicle data 2–3 times faster than standard OBD2 tools. It features a bright 2.8-inch LCD color display designed for high-visibility graphic and numeric analysis.
Operating as a true Plug & Play system, it draws power directly from the vehicle's OBDII link once the ignition is switched on, completely bypassing the need for complicated apps or internal battery replacement. The package includes an extra-long 4.5-foot (1.37 m) heavy-duty diagnostic cable, giving technicians the freedom to monitor vehicle parameters comfortably even from outside the cabin.
Compatibility: ✔ Universally supports all standard OBDII and CAN protocols. ✔ Compatible with most 1996 and newer US-based, 2003 and newer EU-based, and Asian domestic or imported models (including passenger cars, SUVs, and light trucks). ✔ Please Note: Firmware update service is compatible with Windows PC operating systems but CANNOT be updated via a MAC PC.
Key Advantages: ✔ Complete Engine Diagnostics – engineered to deliver comprehensive coverage exclusively for the engine system, efficiently reading and erasing Diagnostic Trouble Codes (DTCs) to turn off the Check Engine Light (MIL). ✔ Massive Built-In DTC Index – features an onboard look-up library loaded with over 8,000 generic code definitions, allowing owners to identify fault origins accurately without dealer checkups. ✔ Exhaustive Emission & System Tests – provides advanced diagnostic controls over emission components, including O2 sensor diagnostics, EVAP system leak tests, and onboard monitoring to ensure seamless clearance during annual smog checks. ✔ Live Data Graphing & Telemetry – overlays critical sensor metrics in real-time graphic and numeric formats, enabling users to isolate faulty component readings within seconds. ✔ Integrated Battery Tester – doubles as an efficient 12V battery test module to actively analyze vehicle battery conditions along with diagnostic checks. ✔ Premium Storage & Lifetime Updates – includes a durable, free storage case for field protection alongside free lifetime software update support to adapt seamlessly to upcoming vehicle protocols and software updates.
