Re: Brake Failure Light Flashing even thought reservior is full
Many people in this thread are overlooking the fact that K1200LTs came with two very different ABS systems. The early bikes (like my 2000) had ABS II.
This had a separate single fluid circuits for front and rear brakes. ABS II has two "ABS" lights that flash in unison until the ABS system self test completes after the bike is moving, since it needs to verify the wheel speed sensors. The brakes on an ABS II bike work just like normal brakes without anti-lock if the ABS system fails. Many ABS II fault codes will not clear without either a trip to the dealer, or a GS 911 tool, or a fairly involved procedure that involves pulling connectors off the controller and grounding a pin. Both systems can have faults that are caused by low battery voltage instead of a real failure.
With the later ABS system the brakes loose stopping power if the ABS is not functioning, so unlike ABS II it really needs to be working for safety.
For the last couple years I have lived w/o ABS after my ABS lights started wig wagging about the same time I had to replace my battery. Last time I replaced the battery I got a cheap lead acid, didn't keep the charge high enough last winter and just switched back to an AGM battery. (No mtce charge needed, just disconnect the negative cable for the winter so the bike doesn't drain it.)
I just purchased a GS-911, reset the (piston) fault that was reported,
and the ABS appears to be working fine again.
If anyone is close enough to Woodford WI, that you'd like to come by and have your engine or ABS fault codes read or reset, PM or email me, and I'll do it no charge if we can arrange an agreeable time and place to meet. Some "service" functions of the GS 911 are limited to 10 bikes in the version I got (but not fault code reads or resets), if you want one of those "service" functions performed, I'd do that too, but ask for a 1 time $25 fee, so by the time I
get to 10 bikes I have the upgrade to the unlimited version paid for.
(As a bonus, there's plenty of great riding in this area.)
