My old PCM caused trouble for years. I finally figured it was the problem and replaced it.
Envoy has been running great ever since. I still have the old PCM sitting around. I'm curious if anyone fixes these things?
If not, I might try unpotting everything and see if it's anything obvious like a fried capacitor, etc.
If it's not repairable, I'm tempted to use it for target practice as it left me stranded on the side of numerous times and cost me hundreds of dollars in wasted diagnostic fees. Neither the GMC or Chevy dealership techs could figure it out.
It wasn't until I just said "F-it" and bought a good used one, had it VIN matched, installed, and pass code reset that it finally was fixed.
