In this paper we introduce a diiusive scaling to a hyperbolic system with relaxation and prove that, under such a scaling, the solution converges to that of a nonlinear convection-diiusion equation. Using energy estimates, such a limit is justiied with the initial data prescribed around a traveling wave solution of the relaxation system.
