Abs help - 01' r1150gs

NewtoADV · 01-22-2013, 06:56 PM

HELP!!! My ABS is going crazy. I had the ABS lights go off last week (blinking alternately at one second intervals). I read that the system is really fickle with the battery voltage, so I changed to a new Odyssey battery and reset the ABS. It worked for one day, but all of a sudden it happened again. The lights were blinking together when I turned on the bike, but as I accelerated the self diagnosis (the one the ABS system does prior to accelerating to 3mph) made a big noise. The noise was more like a “clunk”. (It sounds like a piston.) Then the ABS lights would go back to blinking alternately at one second intervals. I then realized that it made the same noise the first time this happened last week. I reset the system again and the same thing happened when I accelerated after starting. When I start and accelerate the bike with no ABS, there is no “clunk” noise.
Brake fluid levels are fine and no other problems with the brakes functioning.

I’m not too worried about the brakes failing, but I’d like to figure out if the ABS is dead.

And, if it is…… I’m not interested in replacing it. Way too much $$$$$ for a new ABS. I’m thinking of just running the bike without the ABS.

Let me know if anyone has ever had this problem and if you were able to fix it.

Also, any advice on how to move forward with this would be much appreciated.

Thank you all in advance for your time.

Sounds like there is a failure in the hydro unit. These units can be repaired for a couple hundred dollars with warranty.

Contact Module Master in Moscow, ID.

I'll look into the hydro unit. No warranty on the bike.

Thanks

Module Masters warranties their work is what I think was meant by the warranty comment.

Thanks for the clarification. I think I need to get some sleep.

The clunk when you first take off from a stop is normal. The lights flashing after you take off is not.

In all modesty, may I suggest that you read carefully all the advices that are collected in the GSpot FAQ?
There might be some nuggets for you there.

My post should have been written more clearly. My apologies.

Module Master provides a lengthy warranty on the repaired ABS units providing you with more warranty protection than if the ABS had been replaced with a factory part.

Before you disconnect the ABS, I would call Module Master and discuss your problem. Your ABS system could save your life one day. I would have it repaired.

If you have decided to get rid of it, there may be others who might buy it from you.

Or, you could be benevolent and donate it as a core part for eventual repair for someone who needs one...

Philanthropy aside, I would fix it.

TaSK is correct. (He is also very fortunate in that he has Gina Lollobrigida and Sophia Loren for neighbors. I hear that they both come by and visit on their Ducatis from time to time

)

Some while back, a fellow did a write up of his disassembly of his ABSII hydro unit, how to take it apart and reassemble it and how to repair the mechanical faults. If you are adventurous, you might want to read that thread.

Here is a long thread from when I experienced the same thing.
http://www.advrider.com/forums/showthread.php?t=457863

It discusses a procedure for cleaning the pistons that has worked for some. If that doesn't work, then the rebuild route sounds like a good idea. That wasn't an option at the time. I bought a used unit from a different model and swapped the hydro portion of it into my ABS controller. That worked well for me and is discussed in the thread.

Another thought;

Is your bike still wearing the OE rubber brake lines? These lines are known to deteriorate and shed rubber debris into the brake system and ABS hydro unit causing malfunctions. If the lines are OE, I would at the very least closely inspect them for deterioration.

New aftermarket lines are constructed with different materials and are covered with SS braid providing strength and durability and will not shed debris into the brake system. Aftermarket lines can even been had in a variety of colors.

Try these folks....
