What the KW850 OBD2 scanner does

The KW850 is a handheld diagnostic tool for vehicle owners and DIY mechanics who want to read and clear engine fault codes without visiting a workshop. It covers full OBDII and EOBD functions for the engine system on most 1996 US-based, 2003 EU-based and Asian OBDII and CAN vehicles. A built-in library with over 8 000 generic code definitions helps identify the cause of a check-engine light.

How it fits into a vehicle diagnostic routine

The scanner plugs directly into the OBD II port and powers from the vehicle, so no separate battery or app installation is required. An extra-long 4.5 ft cable lets you operate the unit from outside the car while the ignition is on. Free lifetime software updates keep the tool compatible with newer vehicles, although updates cannot be performed on a Mac computer.

Behaviour during extended diagnostic sessions

The 2.8 inch colour LCD shows live sensor data in both graphical and numeric form, allowing you to monitor O2 sensor output, EVAP system status and on-board monitor results over time. Optimised software algorithms make the diagnosis process two to three times faster than basic scanners, reducing the time the engine runs while you troubleshoot. The included storage case protects the unit between uses.

Questions about this item

How long can I run the KW850 scanner continuously before the cable length limits where I can work?

The 4.5 ft diagnostic cable lets you move around the engine bay or step outside the vehicle while the tool stays plugged into the OBD-II port.

Does the KW850 generate noticeable heat or fan noise during extended diagnostic sessions?

The unit has no fan and draws power directly from the vehicle's OBD-II port, so it runs silently and stays cool during all-day use.

What must my vehicle already have for the KW850 to function?

Your car needs a standard OBD-II port; the scanner supports all OBD-II protocols on most 1996 US, 2003 EU and Asian vehicles.
