Would a defective 411 PCM throw a code?

After all the issues I seem to have with my tune, I honestly think something is wrong with the PCM. Would it throw some sort of code if it was defective?

doubtful Ive yet to have seen any module throw a code on itself normally the can cars will run diagnostic on neighboring modules but have never seen one throw codes on itself. Is it unresponsive? Trying to run check engine diag with no communication check your fuses. Alot of times that can take care of that issue, whats going on with it? Nothing or what lil more info on what its doing could help aid alot.

P0601 comes to mind. Internal memory fault. I have seen a PCM throw a code for itself, I have also seen them be bad and not throw any codes. What tune issues are you having?

I have intermittent issues....The idle hang I have been dealing with for months. I can drive the car around and it returns to idle just fine but other times it will hang! I know its computer related because its the IAC that remains open, its not a leak. The car drives fantastic other wise.

I would assume if it was a tuning problem, it would do it all the time, but it doesn't. It can drive perfect, than act like a bitch.

Do you have a current log of it and your current hpt tune?
