P0601 internal control module memory check sum error
My van failed the OBD test with this code. the starter was replaced abvout a month & 1/2 ago is this connected? I can only do basic repairs but want to know so I don't get overcharged if I have to bring it into a repair shop.

The diagnostic chart is pretty straight forward on this one. It says if this code is stored in memory, replace the PCM. Once it is replaced you will need to drive it a few days for the OBD readiness monitors to reset.
