Replace PCM? on 2002 Chrysler PT Cruiser

Diagnostic code is P0601. There is something about "check Sum". Is this the main computer? will replacing it turn off the engine light? I will have to accomplish this myself, so what is the most reputable brand of used/reconditioned units, and when the thing is swapped out, do I just stick in the key, crank it over and drive?

Check Sum error is an internal defect and the PCM must be replaced. I would recommend only replacing it with a MOPAR (Chrysler) new or remanufactured component. After replacing, the module must be encoded with the vehicle VIN number by your local dealership with the proper scan tool.
