Abstract: A selective catalytic reduction thawing control system that can distinguish between a thawing failure and a malfunction and can prevent a malfunction of a supply module (“SM”) pump. The thawing control system includes a thawing control unit that detects a pressure inside the supply module when the SM pump is operated, and stops the operation of the SM pump and continues thawing of urea water when the pressure is less than a predetermined value.
