Hi All,

This is part of a much-longer story, but where I have ended up in the latest installment is that my ABS light is full on (1992 K75ABS) and won’t go off.



Thought, please? Reset again? I got a 12v test light and have tried testing the system by using the blue plug on the right side of the bike, but I don't get ANY blinking light in the tester...

I can re-tell the whole story, but don't want to bore anyone. This all started when I tried to re-set the system after replacing the rear brake light bulb. The red warning light above the neutral light will go off after riding for a few minutes, but the ABS isn't working and the light is full on.

I KNOW that the ABS module is still working because it just seems coincidental to me that it would fail at exactly the same time as the attempted re-set. Unless the re-set burned the system up in some way.

The bike stops fine, but I know the ABS is not currently engaging.

Would a faulty rear brake switch cause this?

Thanks all! I've SCOURED every post I can find, so I am only asking because I can't seem to get the tester to blink even once, so I don't know if that's a symptom or a cause...

Have a look at Tosi Tabuki's site there should be some good info there and if it needs fixing in the  control module he is the one to do it.

Thanks all. I think I have to find a mechanic and show them this info.

I’m a half decent shade tree mechanic, but electrics baffle me.

Thanks again.
