I went for a ride yesterday, temp in the morning had hit 34 degrees, so the garage was cold most of the night. I waited for it to hit a balmy 62 degrees, to fill up the bike and put my second 6 oz of Chevron Techron in the bike. When I started it up it cranked slow but took with full choke.
I noticed the ABS lights flashing alternatively. This is not normal during pre-start test, but sometimes happens during first few minutes of ride, I usually ride a few minutes, stop put in
Neutral, and re-start, clearing the fault. This did not happen, so I went ahead and rode to Texaco (which also has Techron in the fuel).
After fill up, still flashing ABS lights. The ABS clear button does work, but it only last for 4-5 mins.
When I got home I read the following article, and starting to rig up my own wire jumper.

ABS2
ABS2 was used on K1100 from 1994 onwards, R1100RS/RT/GS/R, R1200C, and to 2000~2002 on the R1100S, R1150GS, and K12 models.* The K11 ABS2 uses the same two warning lights as ABS1: the ABS light and the bulb monitor light. On Oilheads and K12s, it has two distinct lights of its own. At key-on, the two lights will flash together and continue to do so until the self-test is complete (which doesn't happen until you start to ride away), at which time they extinguish. If the self-test fails, they will begin to flash alternately. The exact moment when the fault happens will help you know what caused it: if it happens before you start the engine it is an item that is tested at power-up. If it fails when you start the engine, it is almost certainly low battery voltage. And if it fails when you ride away, it's probably a modulator or a wheel speed sensor.
Sometimes ABS2 will fault without showing a fault code that you can read without the diagnostic computer.
Resetting ABS2 on early bike
- Locate the diagnostic connector under the seat. Remove it from the blanking plug.
- Insert one end of 20 cm wire into the middle socket of this connector.
- Ground the other end firmly to a metal bolt in the area (and keep grounded).
- Turn on ignition. You should see the lights flash alternately.
- Hold ABS button down for about 8 seconds. The bottom ABS light will stay on, and the top one off.
- Release the ABS button. If you have successfully reset the ABS, both ABS lights will come on. If you have failed to count to 8, or your ground is not good, the top ABS light will stay off.
- Turn off ignition, remove wire.
I ordered a new oil indicator glass, the bike is coming up on 9 years old, the glass is a bit smudged on the inside, and I figure it will prevent the dreaded pop off disaster, only 32 bucks at Max BMW.
