2009 k1200lt abs lights

I purchased used 3 months ago at a dealer and opted to not purchase warranty. A couple of weeks ago 14 mile ride to town I got a red solid general warning and 4htz flashing abs with residual breaking .On the way back started it and worked fine going home this has happened last 5 rides to town.lights indicate one circuit failure and appears to be rear brake .Brake lights work pads and fluids good.with key on engine off front and rear brakes energize servo, any ideas other than sevo or am i screwed. Thanks Jack

Re: 2009 k1200lt abs lights

There are a few things that can cause this other than a hard failure. Often on the rear circuits it is a pressure fault (only way to be sure is run a GS-911 test) that can be fixed with the removal and cleaning of the domed relief valve. Also a low battery (appears to work fine but is weak) can cause a lot of grief. If you have not had the recommended fluid flushes (annual and semiannual) often that helps clear a fault but don't hold your breath. There is a listing of members who have GS-911 unit in the "Bike Talk" section, maybe someone is close by and can assist.

Re: 2009 k1200lt abs lights

I have a 2007 with 22000 miles on it I bought it 2 years ago and had the same problem. I tried brake flushes but the fluid was so contaminated that the integrated module was toast. Fix was a new module. $2,200 later all fixed. I know flush my system every year using tube vids from northern Illinois BMW. Don't forget the clutch flush also.

Re: 2009 k1200lt abs lights

Hope that works for you. Make sure you put fluid flushes for brake and clutch systems on your annual maintenance to do list.
Enjoy the ride

Angry Re: 2009 k1200lt abs lights

My 2005 K1200LT has slowly got worse with the abs issue over the last 12 months, I have had all the issues that you have but yesterday it failed totally, reverting to lever pressure braking only, a bit of a shock when you are used to servo assist. Admittedly the light was flashing at 4 htz but I have done many trips with it on, and have resigned myself to a new unit. I have today bled the system through and the colour of the fluid was not good. I have had it regularly serviced but not by a main dealer as it is so pricey, I guess that they haven't changed or adjusted the fluid levels (post new brake pads) as the front res was over filled and flooded dot4 all over the Tupperware. Depressing and hard to prove!

Anyway I'm not impressed as the bike has only got 22000 miles on the clock and is always garaged. It seems to fault to total failure when the rear brake is applied, I also have intermittent servo action on the rear. There are loads of bleed valves on the top of my ABS unit. The electronic connector block has at least 50 pins. Should I struggle on with it or just take it to the main dealer and suck up the pain! Main dealers here in the UK are few and far between and very expensive

Many systems are as susceptible to age as to mileage and ABS is one of them. An old saying is that "you rust out faster than you wear out", and this applies to mechanical systems and people alike!

22,000 miles over 10 years is very low mileage and very hard on a motorcycle. Oil drains off parts letting them rust, fluids oxidize and form gum or deposits, etc. It isn't the bike's fault that it was ridden only a little more than 2K miles per year on average and the fluids weren't changed according to the manufacturer's recommendations.

And I always tie a large plastic garbage bag around the handlebar as a "bib" before removing either master cylinder cover. Even if not overfilled, all it takes is a slight bump to the handlebar to make a mess of your paint. And keep a water hose handy when working with brake fluid.

Re: 2009 k1200lt abs lights

Thanks for the tip with the bib Voyager, I know the issues and I guess I'm just annoyed with myself as much as anything, likely to cost over 1500 maybe a bit more, plus I've wasted an entire day messing with it and most likely doing more harm than good!
