fluid wouldnt cause a screeching noise but is the sound in the same location as the post you presented?
they generally last a very long time before the need replacing. they will throw a code when they definitely have an issue until then its more of an annoyance of the noise when cold is all.
what kind is it. it may not read codes from the abs unit.
those both will not read abs codes. they are strictly for smog related codes that are in engine modules not abs modules. but when and if you see an abs light on with the vsc and trac light then you know there is a code in that system. and most likely it will that part that has failed.
