ABS cured thanks to forum

I know this is an old subject but I just want forum members to know that their sharing of info really helps.

 

When I bought my 1100rt a couple of weeks ago the ABS was showing a constant fault.

 

After reading previous posts and advice on this board, the most obvious cause was a weak battery although the bike has never struggled to start.

 

The ABS fault did not appear until immediately after I had pressed the starter button and the engine was running. The bulk of advice was that this was a battery problem.

 

Here's the happy ending. I've just replaced the battery and no more ABS fault. Fantastic.

Sorry, Russell is already gonna have mine.

 

Glad you got the ABS fixed.

I'm sorry, I thought all RT riders looked like me. At least I haven't progressed to the sandals with black socks and smoking a pipe. Perhaps I should allow myself more time.

The faults WILL come back in a few months. Here is a way to prevent them permanently.....

Why?

Thank your lucky stars you don't have integral ABS. You'd be at your dealer.

Just because most batteries will not supply enough starting current to the starter AND satisfy the stupid ABS voltage test after they are 1 or two years old. BMW 'fixed' it in the first generation of Integral brakes but almost all of the ABS-II bikes will eventually see the low voltage fault when the battery gets a little weak.

WOW!!! Nice walkthrough, Mick!!

 

We had that same problem on Leslie's Cruiser and found the problem through this site.

I also had to replace the battery on mine, and occasionally since then the fault code has come up. what I am doing temparily is having a trickle charger on the bike for a half hour before I start the bike, since then no problems, and it seems good for that day.Eventually the wireing mod will have to be done.Seems like a good winter project.
