2 GS-911 BASICS

2.1 What is GS-911?

The Hex GS-911 is a compact, portable diagnostic tool for BMW

motorcycles. GS-911 makes technical problem-solving easier by giving

you greater insight into the electronics of your motorcycle.

Depending on which GS-911 device you use, the device can

communicate wirelessly or by USB, and with control devices such as

computers, tablets and smart phones.

GS-911 can serve as a workshop-based tool, and can also be carried with

you while you are riding your motorcycle.

2.2 Terminology

In this manual, you will see the terms GS-911 device and Control device.

A GS-911 or GS-911 device is the 3-pin, 10-pin round, or 16-pin

OBD-II GS-911 device that physically connects to the motorcycle.

A Control device is any digital device that can communicate with a

GS-911 device, read the motorcycle’s electronic data and fault

codes, and control the motorcycle’s components. Depending on

your needs, a Control device might be a desktop or laptop

computer, or a Wi-Fi-equipped mobile phone or tablet computer.

2.3 How does GS-911 work?

By connecting a GS-911 to your BMW motorcycle, you can diagnose

almost any electronic problem you encounter.

A modern motorcycle actually starts the diagnostic process itself. Often, it

does this by logging a fault code to its on-board memory. A fault code is

simply data that describes the problem, keeps a count of how many times

the problem has happened, and says whether the problem still exists. It

may also include information on what the motorcycle thinks might be

causing the problem.

In some cases, you might see a Master Caution light (below, left) or a

Master Warning light (below, right) on your motorcycle’s instrument

cluster.

On newer BMWs, you may see information regarding a problem on the

motorcycle’s instrument display. In some cases, the engine warning icon

or ABS warning icon may come on.

Hex GS-911 for BMW Motorcycles

_________________________________________________________________________________________________

Most steady-state or intermittent electronic problems and faults may go

unnoticed because no warning lights or icons appear. Sometimes, they

are not recognised by the motorcycle’s software as a problem (and

therefore do not generate fault codes). GS-911 can be used to diagnose

such problems by reading software values in real time.

When GS-911 is connected to the motorcycle, it shows you all fault codes

that have been logged. Depending on the motorcycle model, the GS-911

will likely also include Service functions that allow you to test suspect

components yourself.

GS-911 will not damage your motorcycle. It works in exactly the same way

as the diagnostic equipment that automotive dealers use to find and repair

problems.

GS-911 powers itself on whenever it is connected to a motorcycle

or to a computer’s USB port.

Depending on the commands it receives, GS-911 can passively

read information (like fault codes) from control units, and actively

control hardware components (for example, by changing On/Off

status).

GS-911 is easy to use and fail-safe. The GS-911 and its software

cannot damage a motorcycle in any way.

GS-911 can be ‘hot plugged’, and does not need to be ‘ejected’ or

‘safely removed’.

2.4 Choosing the right GS-911 device

A number of different GS-911s have been produced in response to

changing hardware and software technologies.

If you need help with choosing the correct GS-911 for your needs, go to
