What is the difference between abs control unit and the abs module? on 2004 Nissan Quest

Mi warranty pay for the abs control unit but the mechanic says the problem is the abs module

Your warranty company may be calling the hydraulic valve assembly the "ASE Control Unit" and the electronic brain the "ABS Module" But these names can be used interchangeably. I would recommend you have your insurance company explain what they mean by "ABS Control Unit".
