Couple of things to ask:
- Is the PCM stock or has it been programmed? I'm aware from previus cases where the chip has been changed they don't work the same as factory and the V2 software does not work with them.
- Do you have another vehicle (friend perhaps) that you might test with? That would validate a few things (cable, configuration).
