ABS problem results

[robasay]

Ok gang this is the results of my ABS problem.

1st. The battery was bad. Battery was replaced but the problems still exsisted.

2nd. There is a relay that is attached to the ABS unit. It had to be removed cleaned and given a little rap. Replaced and everything works fine now.

Victory BMW of Chandler, AZ did the work. I called them first thing this morning and spoke to the Service manager and explained that I wanted them to make sure the battery was good and to check the sensor clearance were correct. Jim told me the computer read would tell them if there were battery or sensor problems. Wow, I am from the old school where you used feeler gages to check clearances. Did not realize the computer could do that job specifically.

So I did not have to spend $1700 dollars on parts and 6 hrs of labor. Yea!!!
So now I can still afford new shocks and steering dampener.

Thanks to all who responed with ideas of what the problem may have been.

Any idea where this ABS relay is? I think I try tapping on mine.

I've not had ABS for about 8 months...and I'm pissed about it. I got a 12 year old GMC truck with 130K that's never given me any ABS problems...but the ULTIMATE MACHINE has had more ABS troubles in 30K miles than I thought possible. :mad:

Of course, I probably wouldn't know if I fixed it...cause I'd next have to drive 4 1/2 hours, one way, to my nearest BMW shop to get them to clear the computer before it would recognize the fix and allow it to work again.

You can always clear the errors out of your computer by pulling the fuse and letting it all sit for a few hours.

Unless, I'm badly mistaken, mis-informed, ignorant and smell badly.

wouldn't be the first time....

I would replace the relay. A sealed relay that needs to be cleaned (and rapped) needs to be replaced.... unless you like having brake problems!

According to the Service manager. To get to the relay you have to pull the gas tank, which means pulling the skin. The relay is covered by one of the supports for the tank at the front of the ABS unit.

As far as replacing the relay as apposed to cleaning the contacts and lightly tapping the relay. I believe the light tap approach would be first on my list. You can replace the relay, however.

According to service manager this relay sticking problems also occurs with the starter relay and there it is a bigger job pulling the starter. The relay problems usually start with a bad battery. So if you have not had a bad battery then your ABS problem may be something else.

The cost of the new gel battery was $100.00 then all the rest $333.00 was for labor replacing the battery and clearing the relay. So it may be easier to take it to you favorite dealer and have them check the relay.

In my relay they wanted to get to it to put a meter on it then cleaned the contacts.

I ended up rapping hte relay when this happened to me about a year ago - battery went bad, then the alternator drive shaft went blooey.

all fixed under my aftermarket extended warranty.

Can one of you guys get a pic of the relay? That might be helpful to have as part of this thread.

My thoughts exactly. So far I haven't found it on any of the parts diagrams.

Well, I have been having ABS problems for the last month and a half. A really slow flash between the two ABS lights in the dash, about second delay between the changes. I PM'ed Raffy about when he put the PC680 in Rover and he told me about 4 years ago. So I went bought a new one from Batteries Plus and installed it in the bike. Now the lights wig wag but about a half a second between changes, which is what I think is about correct before the rolling health check. I've pulled the fuse to Moronic to reset the throttle sensor, because I forgot to do that after putting the battery in. If this doesn't let the bike recover the ABS health check in the morning, I'll ride up to the dealer and have them reset the computer. Only problem with that is, I'll have to fill up with gas before I go and you know what that's gonna due to the low gas level indicator on the dash. :rolleyes:
