2001 Dodge Caravan smog and P0601 internal control module m

Computer problem
2001 Dodge Caravan 6 cyl Front Wheel Drive Automatic +150k miles

does anyone know how to resolve this problem, the van runs great with no problems, but I need to pass smog. My vehicle passes every test except the error from the computer "smog and P0601 internal control module memory check sum error", am I screwed?
