Apparently a new IPM needs TruckCom applied to it and all software updated before it will work. Once dealer tech obtained the right/latest software for this lift it took him like 5 minutes to get rid of the code.... prior to him obtaining the correct software version we were getting no where. He wouldn't tell me if it was the new software OR he had to copy the CID and MCU to the IPM but, whichever, you need TruckCom and his laptop to do it. Swapping a IPM from one truck was to another successful..... but not a new one out of the box.
