Hyper Sensitive ABS

[Greenham]

I searched the forums and found a good number of links explaining the "flashing ABS" light as an indicator that the system detected some type of out of sync event. Turning the bike off it will reset.

What I have noticed on mu 05 is that it seems to happen ALL THE TIME... Today for example I went for a 150 mile ride I would estimate the ABS light flashed for 2/3 of that trip. I would stop, reset it and it would clear for some time and then I'd look down and it was flashing again.

Previous advice was rough roads could cause such "out of sync" And indeed that has caused a few of these, but does anyone have any other possible causes/tests/diagnostic clues to what can only be described as excessive sensitive ABS system.

Check that the rear brake isn't binding, can occur if the brake pedal needs lubricating.

The brake light being on seems to upset the ABS and it shows its displeasure by putting on its light.

If you don't have a ABS test lead, wire in a switch or bridge out the wires in the plug and perform a diagnostic on the ABS.

Not true on 1st gens. The ABS light doesn't come on when the brake switch is always activated. Just the brake light stays on. BTDT many times.

I'd suspect a problem with one of the wheel speed encoders. Pull the error codes from the ABS ECU and it should tell you what's going on.

Ah, then I apologise for the miss-information.

Never say you're sorry. It's a sign of weakness.

So after reading these responses and a bit more Google Research I found someone who had a VERY SIMILAR SYMPTOM. After paying his "Stealer" 4hrs of labor they removed the front wheel and re-seated the ABS sensor ring, saying they believed it was a slight mis-alignment. Having recently done a front and rear tire change, it seems as good a place as any to start.
