I stopped my bike. And everything is fine. Went in to get a coffee. Got on my bike and turn the key and the ABS wigwag started and I can't believe anything could screw up in the two minutes I was off the bike. Any suggestions :brick:

Could be a low voltage fault if you didn't ride far enough to re-charge the battery.

You are lucky you have a 2000 model year bike. If you had the new style ABS you would be pushing it home. The old style like ours work just fine when the ABS lights are doing their dance. Just no ABS. Doesn't take any longer to stop.

Sorry they are wig wagging.

Procedure in above link does work. Its a PITA to get to the connector and there is a good chance just resetting it will not solve the basic issue. If you are lucky it is a sensor gap or something simple (but clues can be had from the fault codes).

My issue was the computer which last I heard was over $2k for the part alone.

I have had this happen. An overnight on the BatteryTender and all was right with the world.

If I remember correctly, some times you just have to add a teaspoon or so the the rear reservoir.

I also have a 2000 and mine has done that a couple of times. That and some other unrelated symptoms led me to suspect the battery was reaching its life limit. I replaced the battery a couple of month ago, and all is well. Do you know the age of your battery?

I Like The ABS...............But I have also had the wig / wag on my 2000 LT.

The procedure in the thread by BDC works. ( I wish that it was in the Hall Of Wisdom )
I was able to read my fault code, ( I believe it was the control unit ) and reset the fault.
The fault came back on my next ride,......so I reset it again,..then went out and "hammered" the brakes. Front then rear, really made the ABS do it's job.
The fault has stayed 'gone' for a couple thousand miles now.

It's worth a try.

IMHO best way to keep ABS-modulator healthy is a) change brake fluid regularly b) Put it to work regularly

Since I had to put mega$ in to new ABS-modulator I have had a habit of putting ABS to work everytime I return from ride. This way I keep myself convinced it really works when needed, train "full-power" / emergency braking and hope it keeps the unit also in better operational condition than only doing the plunger test when starting to move.

Thanks to everyone one for your ideas. I will investigate them all. I do have a battery tender and the battery is charged every morning. Of course i didn't charge it the night before I stopped for coffee

Hopefully it will turn out to be an easy fix. Maybe not as easy as updating your profile on this site, but still relatively easy. :bmw:

Thanks alot

First of all I would like to thank the individuals that came up with testing the abs because it works great. Secondly I would like to thank the individual on how to reset the abs because it worked great and I have had no problems since. I would make suggestions when working on the plug to the computer and that is to remove the rear passenger assmebly because that allows you to bring the connector out the side to work on it.
:yeah:

You might want to fill out your profile so we know were you are. The GS-911 unit will do the reset through the diagnostic port and some one might be nearby with one. Nobody needs to hide here.

You'll have a different opinion of ABS should you ever need a whole lot of braking power.

In my opinion, ABS is one of the best things ever put on motorcycles. There are times where ABS is not the right thing but for the great majority of us, it is.

Maintain your ABS system and hope you never find yourself needing them.
