KW850 OBD2 CAN BUS Code Reader Car Engine Fault Code Detector Scanner

When a vehicle system fails and the check engine light or MIL comes on, the powertrain control module (PCM) stores fault information in memory. The KW850 OBD2 scanner reads those fault codes from the PCM, helping you determine the nature and location of the fault quickly and accurately. It supports all 10 modes of OBDII test for a complete diagnosis and works on all 1996 and later OBDII compliant US, European and Asian vehicles. The KW850 features a unique patented One-Click I/M Readiness Key, TFT colour display and built-in speaker, allowing users to do their jobs faster. Thousands of troubleshooter code tips help technicians save diagnosis and repair time.

Features and Functions

The KW850 is built for complete OBDII diagnosis. It retrieves generic and manufacturer-specific codes, turns off the check engine light, clears codes and resets monitors. It also displays DTC definitions on the unit screen and views freeze frame data, making it a practical tool for both professional technicians and informed vehicle owners.

Code Reading and Clearing

The scanner easily determines the cause of the Check Engine Light (MIL). It retrieves generic codes (P0, P2, P3, and U0) and manufacturer specific codes (P1, P3, and U1). It turns off the Check Engine Light (MIL), clears codes and resets monitors. It also identifies pending codes and performs modules present test. This range of functions supports a thorough diagnostic process.

Live Data and Sensor Tests

The KW850 reads live PCM datastream and displays live O2 sensor test data. It graphs data for 1996 and newer vehicles, reads, stores and playbacks live sensor data, and views freeze frame data. It also displays monitor and I/M readiness status for emissions checks. These features help you observe how systems are performing in real time.

Vehicle Information and Languages

The scanner retrieves vehicle information including VIN, CIN and CVN. It supports eight languages: English, French, German, Dutch, Spanish, Russian, Portuguese and Italian. It also supports CAN (Controller Area Network) and all other current OBD-II protocols. The built-in OBD-II DTC lookup library helps you interpret codes without leaving the device.

Uses and Placement

The KW850 is designed for use in vehicle diagnostics, whether in a professional workshop or for personal vehicle maintenance. Its handheld format and included protective nylon case make it easy to store and transport. The device connects to the vehicle's OBDII port and operates via the vehicle's power.

Professional Workshop Use

Technicians can use the KW850 to quickly read and clear fault codes, check emissions readiness and review live data. The One-Click I/M Readiness Key and built-in speaker support efficient workflow. Memory and battery backup allow off-vehicle data review and analysis, so diagnostic data can be examined away from the vehicle. Printing data via PC is also supported for record-keeping.

Everyday Home Use

For vehicle owners, the KW850 provides a way to understand why the check engine light is on. It displays DTC definitions on the unit screen, so you can see what the code means. It supports all 10 modes of OBDII test, giving a comprehensive view of the vehicle's emissions and diagnostic status. The large easy-to-read backlit LCD screen and TFT colour display make it straightforward to use in different lighting conditions.
