Ok so i took my pcm out and put stock pcm back in. Guess what? NO SES LIGHT. Drove around for 15 min and nothing. So i let the zzp pcm sit over night 10hrs unhooked put back in today ses light was on as soon as car started. Like the pcm did not reset. Heck car started right up.

So is it my zzp pcm that could be causing my problems all my problems?

And how do i reset the codes from the computer with out a reader if unhooking for hours does not work.
