On the base of the maximum principles two-sided estimates for solutions of difference schemes are proved without any assumption of sign-definiteness of input data. Second order unconditional monotone difference scheme for quasilinear convection–diffusion equation on uniform grids is constructed. A priori estimates of the difference solution on uniform norm class="mathmlsrc">class="formulatext stixSupport mathImg" data-mathURL="/science?_ob=MathURL&_method=retrieve&_eid=1-s2.0-S0377042716301716&_mathId=si21.gif&_user=111111111&_pii=S0377042716301716&_rdoc=1&_issn=03770427&md5=976bb837197ede9f42afb6ad5b8a1cd4" title="Click to view the MathML source">Cclass="mathContainer hidden">class="mathCode"> are established. The obtained results are generalized for the case of non-uniform spatial grids. Numerical experiments confirming theoretical results are presented.
