<< < (8/8)

Valentin:
Hello to everybody !
I have a trouble without ending with my abs . I have K1200RS made in later of 2001. I change abs with other from BMW R1100S from 2005, wich model have same ABS pump and electronic board.
I do, bleeding secvence, and I connect battery. The trouble is:
When I turn the engine key switch the electric motor make a self control. But, don't stop. Electric motor for rear part still continue work. The front part servo work ok. When I use front breake the noise from electric and servo work ok. The rear electric motor noise don't stop, and the intonation of it don't change when I push levier for rear break.

Maybe someone from you can help me with any information about this.
Thank you very much, and sorry for my poor englese,

Valentin, just to clarify your configuration, you have K1200RS with servo type of ABS so called iABS. As you mentioned "I change abs with other from BMW R1100S from 2005, wich model have same ABS pump and electronic board."
What do you mean by replacing K1200RS ABS with R1100S ABS?
There are at least two big differences:
- K1200RS ABS modulator is mounted vertically while R1100S is mounted horizontal so bleeding ports are different as well as braking fluid reservoirs. Bleeding process will not be successful with horizontal modulator being mounted vertically and you have to replace oil reservoirs too.
- electronics are differently coded which will result in permanent servo motor running when ignition is on - probably your case?!
It would be the best if you can get GS911 tool and send me/us report (memory readout and reading of pressure sensors) with original K1200RS ABS and original R1100S ABS than I can guide you with some steps .

You need to take your bike to a BMW dealer.  They will "marry" the ABS to the bike.  Without doing that, the ABS will NOT work.
