I have an LS style 411 PCM in my 97 Chevy pick up. I have been trying to do a crank relearn but it doesn't seem that the pcm is communicating right. I noticed that it still had the wrong VIN so I changed that to my vehicles correct VIN. That seemed to open up more tools on the toolbar but the scan tool still says the O2 sensors aren't communicating with my PCM. I also have a lot of invalid PIDS on my PID list such as absolute throttle position which I think you need for relearn. If anyone could help me with this Id appreciate it
