So long story short I needed to put a PCM in my 2011 wrangler sport. When programming it you enter the VIN and it instantly switches it to a VIN for a 2007 Cherokee. So I was told the TIPM is what it uses for that. So I put a new TIPM in thinking maybe a different one was used before I got it. Still no change. Thought maybe PCM (reman) from dealer was defective they warrantied it. Trued again no change. When connecting molar tool what module does it connect with first. Auto scan with snap on scanner won’t work manual scan I can communicate with all modules minus PCM/TCM
