True the calabration code will be different from an 01 to an 03 but unless you changed the complete wiring harness it should still run on the 01 ECM that matches the vin. Unless you completely changed the power train from like a V6 to V8 then your going to either get the donor cars vin or pay to have the system completely reprogrammed.
