KW850 OBD2 Code Reader with CAN BUS and One-Click I/M Readiness

The KW850 OBD2 CAN BUS Code Reader is a diagnostic tool for cars and light vehicles that support OBDII/EOBD. When a vehicle system fails and the fault (MIL) light or check engine light comes on, the powertrain control module (PCM) stores fault information in memory. This scanner reads those fault codes from the PCM, helping you quickly and accurately determine the nature and location of the fault. You can then check the relevant parts and component box lines in a targeted area to eliminate the fault. The KW850 supports all 10 modes of OBDII test for a complete diagnosis. It features a unique patented One-Click I/M Readiness Key, a TFT colour display and a built-in speaker, making it practical for both professional technicians and home mechanics. Thousands of troubleshooter code tips help save diagnosis and repair time. It works on all 1996 and later OBDII compliant US, European and Asian vehicles.

Event or Professional Use

In a professional setting, the KW850 helps technicians quickly retrieve diagnostic trouble codes (DTCs), view freeze frame data, and check I/M readiness status. It can turn off the check engine light, clear codes and reset monitors after repairs. The ability to read live PCM datastream, display live O2 sensor test data, and graph data C (1996 and newer) supports efficient fault finding. The built-in OBD-II DTC lookup library provides on-screen definitions, reducing time spent searching for code meanings.

Everyday Home Use

For home mechanics, the KW850 offers a straightforward way to check why the check engine light is on. It retrieves both generic (P0, P2, P3, U0) and manufacturer-specific (P1, P3, U1) codes. The One-Click I/M Readiness Key makes it easy to check emissions readiness before a test. The device can read, store and playback live sensor data, and perform a modules present test. It also retrieves vehicle information such as VIN, CIN and CVN. Memory/battery backup allows off-vehicle data review and analysis.
