p2536

codes been stored since i had a turbo go bad in my 2011 LML. doesn't set a CEL, can clear it and it always comes back. P2536. told TCM related. ignition accesory circuit. anyone dealt with this before. if i sit in my truck after shutting it off after a minute or so seems like something is waking it up sending power for a few seconds then it powers down again.

You have a wake up voltage problem at the BCM. Code indicates the wake up voltage is below 5V. You may have a bad TCM.

Well found the problem....a wire on the TCM harness was cut. Fixed it and all is good

I'm just glad I waited to get the new TCM programmed. Shop found the broken wire when they were doing my cp3. Was able to return the TCM and save myself 300$
