the abs module has to be replace and do u know might be the cost
Depending on who does it and your location anywhere from $300 -$1000, call around some local shops for some estimates.
Try getting one at a pic a part auto wrecker, most guarantee it to work. I hated my ABS on my Tahoe, it was terrible in the snow so I removed it myself, had to make up a few brake lines to put it back to preABS but never had any more braking problems. A shop will NOT do this for you, if you can't do it for yourself then pay to have it repaired normally.
