2001 blazer 4wd, has the ABS light come on and emergency light, it goes off between incidents of it coming on while driving and being shut off completely. The scanner my mechanic put on it said it is an EBCM relay circuit. Is this a costly repair? Saw on a blog some thought this could be just a need for brake fluid? Thanks for your help.

I got the same problem on my 2001 trail blazer. Intermittent ABS and emergency brake light comes on in the dash. No rhyme or reason as to why it comes on or doesn't. I can get rid of the emergency brake light just pulling the fuse on the drivers side dash fuse box but the ABS light I have no idea.

I've read the supposed fix's too, from low brake fluid to a brake sensor in one of your wheel to a faulty EBCM module. You name it, I've read it.
