ABS repair

Howdy folks, 2000 R1100RT, 20,000 miles. Is it possible (assuming the wheel pick-ups are good), that a line change/upgrade and total system fluid flush could restore functionality to a failed ABS? Or should I just remove the module and send it off for overhaul? Not trying to be lazy here, just don't really know the brand and was wondering if this approach could be a viable strategy or just a waste of good brake fluid ....?
Many thx.
 
It is very possible.
The OE rubber lines deteriorate internally and the bits cause blockages internally.

Start by replacing all the lines with SS teflon.
Flush the entire system with fresh DOT4 and bleed air out.
Then scan and reset any faults present.

At that point if you can still send it to Module Masters for repair.
My bet is you won't have to.
 
Also check your battery voltage. A low battery can also cause an ABS fault when all else is okay.
 
You can also pull the fault codes from the ABS. Some faults are very simple to repair and some mean don't waste anymore time and send it off.

I hope somebody can post a link as to how to pull the codes, I can't find the link.

Anton has a ton of good info on his site. Here's a link to the ABS fault codes and a short description on how to read them: http://www.largiader.com/abs/absfault.html#light

Here's a document about ABS codes and how to build a simple reader from a 1.2K resistor and a common red LED.

I should also note that if you have an analog voltmeter (old school) or a digital meter with analog bar like a good Fluke meter you can read them with just a meter as well. I make a small test box that does the trick.
 
Thanks for the link to that file. If one makes this test box, would it be as effective as the GS-911 hexcode reader they sell or does that unit have more functions?

Lots of ABS info by using the "Tag Cloud" located/accessed at the bottom of the page.

The GS911 has many, many more functions than this.

Just to clarify, the original poster was asking about a 2000 R1100RT and the poster that Paul replied to seems to have an R1100RS. The GS-911 that most folks are buying (with "many, many more functions") do not work with the R1100 bikes. The manufacturer makes a different version of the GS-911 that works only with the R1100 bikes that have the 3 pin diagnostic plug under the seat. That version - $99 if I recall - has very limited functionality. It reads and can clear ABS codes, motronic codes and confirms if the TPS setting is in spec - that's about all.

On 1100 models, the functions are limited compared to 1150 and up with the 1100S being the oddball. There is an adapter you need for the earlier three pin diagnostic plug. It will read codes however.:thumb

edit: got beat to the punch by Michael
 
GSAddict and I hooked up his GS911 (with 1100 adaptor) on my '00 1100RT and as posted already, it will read engine and ABS codes and reset them. That's about it and it's due to the limitations of the Motronic 2.2 ECU. The 1150 has a Motronic 2.4 which provides a lot more info that the GS911 can display making it very useful indeed. If you have a 1200 they are invaluable and really a necessary tool.

So I feel it is not useful for the 1100 but very useful for the 1150 and onwards. But I can do everything the GS911 provides on my 1100 with a 1.2K resistor, a red LED and a short jumper wire. So buying a GS911 for my RT would be like buying a Cray computer to write an entry level C program where you write just enough code to display "Hello World" on your screen.

It would be the fastest "Hello World" in the world :)
Perhaps someone in the (your) group has one with an extra VIN slot.

You betcha! Familiar with VME slots.. not VIN though. Back in my former life I installed, upgraded and repaired a ton of semiconductor process tools with our automation solutions. Sony in Japan, IBM in Fishkill NY and Cray Super Computers in Chippewa Falls WI are amoung some of the most memorable sites I visited worldwide but Cray just blew me away.

Picture a chip fab and super computer assembly facility in the middle of a corn field in Wisconsin. Walk into the front lobby and they have one of the original models cross sectioned right there. I spent a very long time just examining the thing till finally the receptionist came out and asked me what I was doing there. It was absolutely amazing. I had only read about this water cooled wonder but to see it cut open like that was a real treat. Been there a couple of times or more over the years and it still ranks as one of my favourites. Seymour Cray truly was a genius.

That was what I was getting at. Started scrounging up the parts to make the test box as I figure I will save a hundred to help pay off the Wilbers I ordered.

Your water cooling comment reminded me of my training in the Army Signal corp. school in Ft Monmouth. We had water colder vacuum tubed transmitters in our labs, transistors were a new fangled device, at least to the Army electronics in 1965.

Interesting. As a Canuck I had a heck of a time getting clearance to install a new system of automated battery cylcers at US Army Labcom, Ft Monmouth NJ way back in the eighties. They posted a young guard outside the door of the lab I was working in. I was told to never leave the room without him as an escort and he carried an M16 to enforce that rule... Very interesting place to work! Sandia Labs in Albuquerque was even more strict. Even the guard shack was top secret!

PS: You're going to love the Wilbers on that bike. I have a set on my 1100RT and they transformed the ride. The improvement over the stock Showa shocks is really quite noticeable.
 
Knowing you, I can understand their trepidation with having you on site. :laugh

What? I only gave him the slip that one time! :bolt

Dude went for a break. I had too much coffee that morning and needed to relieve myself down the hall. I pled guilty to peeing without a permit. :blush

Many thx.

Update: In order to salt away this thread I figured an update would be prudent. I finally got to this failed ABS snag on my bike by replacing the lines with a set from Galfer, and a total fluid flush. Performed a reset and I'm happy to report the ABS appears to function normally.
Cheers, Flhfxd.

Great outcome! Annual brake fluid flush should keep that relatively simple ABS system clean and happy for years to come.
