650GS Diagnostics

The F650GS has basic onboard diagnostics capability, the information below outlines the basics of the system and options for connection and diagnosis of problems. If you see any errors or have additional information contact us.

Diagnostics Connection and Protocol

Connection is via a proprietary 10 pin socket above the radiator on the
RHS side of the machine.

Diagnostics Software

Software for the GS is the only component yet to be resolved and documented. While the physical and protocol layers are as per OBDII with extensions, the addresses for each component are different. Open source software should be able to be modified easily to perform fault code read out and clearing of fault codes. See the software page for further information on this subject.

Some BMW factory and dealer software is discussed in enthusiast forums on-line but use of the software would
be questionable & perhaps not recommended. The factory software would enable complete reprogramming of modules & could result in inoperable ECU's so caution would be advisable.


Diagnostic Devices

There are two commercial products for diagnostics on the 650GS. They are the GS911 and the MT1

GS911 by Hexcode ZA

The GS911 has been under development for many years and provides access to diagnostics information while on the road via bluetooth to a mobile phone and a PC system back in the workshop.

This tool is all most owners would need and is reasonably priced

Chinese clones are being offered on ebay so be wary of cheap prices

MT1 by Jerome

The MT1 has been developed by a C1 enthusiast in the UK, it has an inbuilt display. Little is known about the capabilities of the device with regard to the 650GS and other BMW models beyond the C1.
