    ABS Brakes

    I have a 2003 K1200 LT with ABS Brakes. My problem is I get a continuos flashing warning light next to the ABS light sometimes when I first start the bike. Other times the ABS light flashes like it is suppose to and then goes out. Anybody with any idea's of how to fix, could sure use your help. Closest BMW Dealer 4 hours away.

    Thanks for any and all suggestions

    1st- how old is your battery?

    2nd- have you recently let the bike sit for a while without plugging into a charger?

    Many times brick ABS problems are caused by low battery voltage. I have had it happen intermittantly on my K1100RS- the ancestor to your LT- especially during colder weather when starting is harder on the battery and grip heaters &/or heated gear draws more on the electrical system.

    Good luck,

    Yes, ABS relies on electric motors to function.

    Since ABS is a safety system, it's a safety warning to let you know system voltage may not be enough to operate the system.

    Thanks for the information. Checked battery found ground cable slightly corroded and the positive cable loose. Cleaned and tightened and the flashing light went away.

    Thanks again for the info
