Does anyone know how to fix the code or any fixes that have worked before, i have code p0601 and it’s checksum but i don’t want to spend money on witech subscriptions to reflash im only trying to fix the issue to be able to tune the pcm with a handheld tuner since i think it won’t let me from the code being thrown

 

That is a memory failure in the computer. The "Fix" for that is..... replace it.
