I have been searching about problems with the ABS module. It says there is an O-ring that I need to replace. If you have replaced yours before, can you tell me which ring it is on this picture...

When I first got my car the abs light was always on from it self testing every few seconds.(buzzing sound)

Replacing the Cap fixed the light and cut the buzzing in half.

Then wacking it with a bit of wood got rid of the rest of the extra buzzing. (Wacking it clears the air locks in the unit from having the cap leaking, Or if you have the service computer you can do it that way and bleed it.)

Now it only ever makes the buzz sound at low speed (under 20Ks) like it should when self testing.

 

I would bet on #23 in your diagram, at the bottom of the accumulator. That is what failed on mine, FWIW.

 

yeah i wondered about this too...it buzzes when i first start the car.....and sometimes wen i am sitting at a long traffic light.....is this normal or am i having a problem

 

thanks...
