OK...I've read dozens and dozens of posts on the ABS system, here and at several other BMW sites/forums...
Read the factory and the Clymer manual and I cannot find the answer to this question:

What does it mean when both ABS lights are on all the time?
Not flashing at all, just on.

I was getting the alternate flash when she first came home and found the new battery the PO had put in was not fully charged, (11.9V), but after a night on the tender, she will hold 12.8-9V...
Still flashing...
Tried to clear codes, (yes I probably shouldn't have), tried to read codes with the 12V LED, nothing....
Somewhere along the way both lights come on solid and have stayed that way since.
Also the rear sensor gap was way tight, (.40mm),
PO told me he had the rear brakes done, don't know by who...
I managed to open it up by moving the caliper to the minimum gap.
Front was good.

Still need to renew the brake fluid...but it doesn't look bad.

Anyway...just trying to find out what the solid lights mean and trying to avoid a trip to the dealer....

Thanks!

Just a shot in the dark here, but if one of the lights your talking about is the triangle one, check your tail/stop lamp, when my triangle one came on to tell me i had a bulb burnt, it was my tail lamp bulb, but with mine, the ABS flashing light would turn off after it did its check..

Hmm, I didn't realize there were two ABS lights. I've never seen the one on the right(?).

I'd try disconnecting the battery and let the motronic brain re-set itself and see if it persists.

Otherwise I'd suspect the battery, if it was an issue before. My battery just recently went south and one of the warning signs was the flashing ABS lights not going off after I started rolling. I had to stop the engine and restart to get them to clear, and by the next ride the battery was dead.

Sometimes the errors can be persistent - you might try to reset it again, as I remember there are at least two methods (anyone chime in?)

Bob,

Best of luck with the $#!^$!!@ ABS.

But it sounds like you could use the electrical tape mod (to cover over the red abs lights).

I did it once to my K-RS and a couple weeks later the bike fixed itself. Shocked

Go figure.....

Just to throw an extra spanner (wrench) in the works, I've had a similar issue when an alarm system started to go south, and the abs were the first lights to start mucking about. Soon followed by all sorts of Christmas tree effects on the dash before I had the offending article removed. Is it just me, or are alarms on bikes just a 24 carat PITA.

Re: ""Is it just me, or are alarms on bikes just a 24 carat PITA. ""

No DL.... it is NOT just you ! I've used the "SugarHill" tape-mod and to date my ABS lights are still alternately blinking underneath. Some believe it is just a bubble of air trapped in the modulator that is causing the problem, thus far however I have found no way to bleed and modulate at the same time in order to force any residual bubble OUT ! Many of us are in the same boat and continue to ride sans ABS !

Good luck and best regards........// Ernie in NH
