HI
I have a 98 s70 with abs tracs lights on since I have had it
I have done the do it yourself solder job on 2 different modules
but to no avail the lights go out but within 25 miles come on again
sometimes accompanied by a buzzing you can feel in the brake pedal.without applying the brakes.
I am not opposed to having a module proffesionally rebuilt but I wondeer
if my problem is a wheel sensor. because I assume the buzzing is the system
activating because it senses a wheel turning slower or faster than the others
is there a way to clean the sensors or test them with an ohm meter? Does my theroy seem plausable?
thanks for your input

Hi,
IIRC the sensor resistance should be about 1k ohm (850/1994).

I think you would want to check your sensors but I don't know how to accomplish that.

You should also inspect the ABS ring on the axles - you could have crud built-up or even had a tooth fall off.

I Will start with cleaning the sensors and tone rings
and checking their resistance readings. Then see if it makes
a difference
thanks
will post results
