In hptuners I'm getting an unable to locate vcm, verify the cable is connected and the key is in run. I verified power to the obdII, and the mpvi is seeing power and the computer bings when the USB is connected. It has connected no problem the ladt two days. With the KOEO, there are idiot lights on the dash. I'm doing a 3800sc swap and haven't gotten it running yet(vats). I have emailed support and am awaiting a response, I read that possibly the PCM is fried,thus the questioning on how to tell if te PCM is nfg.
