G-Scan in detail

In-depth look at the tool for use on Far-Eastern vehicles

Published:  18 October, 2013

A few months ago we reviewed the G-Scan diagnostic platform, where we tested some of its functions and pronounced it to be good value. Well, as with most diagnostic machines it had too many functions to go through in a few words, so we thought we'd have a further root around in the menus to see what the tool does in more detail.

First and foremost, we should stress that the G-Scan is primarily a tool for Asian vehicles. While it does have coverage on some popular European marques, it is sold as a diagnostic machine for vehicles from further afield. So, if you see more Qashqais than Berlingos should you buy one?

The first thing that we liked was the fact that the tool has its own internal battery (a 'lithium polymer' unit according to the accompanying literature) which means that the device wont reset when there are spikes or dips in the vehicle's electrical system, when cranking the engine, for example.

In terms of coverage, the tool has the OE software for Hyundai and Kia installed - although we should mention that ECU programming for either of these brands are not supported on it. However, other basic and advanced functions work, such as key reprogramming, reset, initialisation and other variant coding. The G-Scan is powered by an internal battery rather than from the vehicle, it can safely be used on a number of Far-Eastern buses and trucks - although the number of Hino, UD Nissans and Hyundai heavy bus models on the UK's roads must be pretty limited.

In common with most modern platforms, the G-Scan has a TFT touch screen as well as a dozen hardware buttons. Slightly more unusual is a memo function which allows users to doodle with a stylus and then capture the screen. The idea is that you could pen your own basic wiring diagrams or highlight a particularly significant piece of data on screen.

Speaking of data, the G-Scan's architecture comprises two processor chips. One of which apparently deals with graphics and so on, leaving the other free to deal solely with processing information of the vehicle.

Another feature that we found interesting (although not one we were able to test) was the 'self-test' function which allows you to discover whether an apparent fault lies with the tool, with the vehicle or (as is usually the case) with the connector or the socket on the vehicle itself.

There's no built-in scope on this tool but it does record and graph live data, which you can replay in 'real time'. For example, if you wish to test-drive a vehicle you can record the data to play back later. There's also a function to place a marker once the fault has occurred so that you can go straight to that point when reviewing the data. You can transfer what you have recorded to a PC either via Wi-Fi connection or with the memory card included with the kit.
