Hello every body, knowing that ABS problem is not a new thing on 850's but I have to ask some help regarding my 1996 850 with 125 K original.
Couple of weeks ago I atempt to open the ABS module and resolder the problem area which was clearly disconnected from the main board which is common on this type of ABS module as you know, by the way I'm electronic repaire tech. and very good familiar with soldering and how to work and repaire electronic circuits. After installation problem didn't solved and the light still going on and off as it was before I cleaned the wheel sensors too there were to much dust and partical stick to the sensores which I cleaned and I was sure I solved the ABS problem but what a dream? my ABS light is on and off most specialy when I'm driving with low speed when the light comes on I have to stop shut the engine and start again and drive for some distance then light will turn off for some time. because I know how the electronic works and what the wheel sensors and relation with the abs module I think might be a bad sensor what you think any idea and thanks for your time and help.

 

You need to have the codes cleared after repairing it. That might be why it is still coming on.
