ABS BRAKES 2000 R1100RT

[Joe Durt]

Particularly when it is cooler outside, my ABS faults out and I have to ride a little and reset them to get them towork correctly.

Any ideas?

 

Thanks,

This sounds like the classic 'low-voltage' fault. You have the choice of a new battery, even though it probably has much more life left in it, or carrying out the ABS-startup mod described here.

Yup....what Andy said. Typical issue caused from a weak battery. A new good quality AGM battery like an Odyssey will fix you right up.

Ditto Andy and Keith, I had the same problem a couple of years ago, put in an Odyssey battery and no problem since. As Andy said, your old battery probably isn't all that bad, I am still using the battery, that I removed, in my lawn tractor and it starts every time.

LOL....me too. My old battery is still going strong in the tractor after 3 more years, but it sure didn't like starting the RT.

If it is strictly a cold issue, don't rule out sensor gaps.

I'm sorry that I do not have all the facts to hand but there is an issue with the ABS circuit in that it is very voltage sensitive. BMW Germany does not recommend using a GEL cell battery as its voltage is slightly lower than a normal battery.

 

This issue was discussed around year 2002 which is not searchable but others here might remember it.

Old(er) battery? Short commutes?

 

Check your battery condition and all your battery connections first then....

One easy solution, if you have access to an AC outlet, is buy yourself a trickle charger (Battery Tender) and a BMW plug.

Then just leave it plugged in to the accessory outlet (behind your left kneek) when you aren't using the bike .

 

You should never experience that problem again !
