On my bmw motorcycle ( r 1100 rt, 1999 ) the two abs red light start flashing alternatively when i put the ignition key on ( the engine not running) and stay like that all the time on the road. everything seems to work well with the brake system. i have tried a couple of thing like grounding the center wire in the communication plug under the seat for 8 second ( the blue/brown wire ), but that does'nt work....can you help me ?. thank's .

There is a simple way to fix it as I've discovered. Start your bike, if lights are flashing ride for a mile or two applying the rear brake a few times. Stop the bike and place on centre stand. switch off motor then restart. Your flashing lights should have gone. Why the flashing happens is if you ride and use your rear brake rarely and then your bike sits for a day or two without use your rear brake assembly fully retracts, ie pads away from disc and ABS gizzmos inactive. The ABS sensor unit then reports extended non use pattern to the onboard 'brain' which activates the warning mode of flashing lights. This has worked for me several times over the last 5 years when its occured. Full ABS operations return. Tried it on a mates bike and it fixed same problem on his.
I dont want to pay for that and your web site is dragging me into pay solution....
