100% standard designed in failure for this module....My 2008 K1200GT turned on the Brake Failure light, constant on during my first ride of the season. I have seen lots of posts with the codes from a GS911, that confirm this is the pump motor brushes.
I am using an OBDLink MX with Motoscan and get codes 5DF0 and 5DF1, both say "Pump motor: Voltage Supply". I have been able to actuate the pump motor a few times, but it is very intermittent.
Can anybody confirm if the 5DF0 and 5DF1 codes are also brush failure?
Module Master lists the codes like this>
Code 24048 (5DF0)
Code 24049 (5DF1)
the great bit about the K1300GT is the module is to the left of the petrol tank and should take you around 30 mins to get it off the bike vs the 5 hours first time I did it on the GS. Left faring panel off and its just sitting there.... brake fluid will go every where.... I'd probably put it in a plastic back as you remove to collect it all... and make sure a new one is there to collect the drips.
the pump motor needs to come off or if your lazy a small hole and lots of contact cleaner in situ will probably fix it for another 2 years - not sure about USA but you can post to these guys for UK riders - you must enclose the info on the two faults.... those two are generic across BM cars and bikes

youtube videos if you want to tackle yourself but at 1200 for a new one and 250 for guaranteed repair why bother.... the other point about DIY is how do you re-crimp the motor correctly, not something you want to fall off
