I've been a member here since 2009, I do not remember anyone replacing the ABS module or unit/pump.
I cant help but ask why you think yours is bad. If some shop is telling you that its bad, I'd consider a different shop. They are not known to fail.
Instrument panel ABS warning lights are (if that is what makes you/them think it is bad) are usually caused by the steering angle sensor, a goofy wheel speed sensor or bad relay in the RCM or fractured solder on the RCM.
