Overview

The KW330 is a proper full-system OBD2 scanner, not just a code reader. It pulls fault codes, clears them, runs engine and battery tests, and streams live data so you can see what the car is actually doing. Handy for the DIYer who wants to know the problem before walking into a shop — and a coupon was listed at the time of writing.
