Its not unusual to have a TIPM connection problem after the recall. They have to do surgery on one of the connectors. The TIPM basically is a computer that takes in commands from other modules and powers things up/down, and monitors current draw... like fuel pumps, starters, lights...
"The Totally Integrated Power Module (TIPM) is a combination unit that performs the functions of the Power Distribution Center (PDC) and the Front Control Module. The TIPM is a printed circuit board based module that contains fuses, internal relays and a microprocessor. The TIPM is located in the engine compartment next to the passenger side strut tower. The B+ cable connects directly to the TIPM via a stud located on top of the unit. The ground connection is via electrical connectors. The TIPM provides the primary means of voltage distribution and protection for the entire vehicle.
The molded plastic TIPM housing includes a base and cover. The TIPM cover is easily opened or removed for service and has a fuse and relay layout map integral to the inside surface of the cover. The TIPM housing base and cover are secured in place via mounting tabs. The mounting tabs secure the TIPM to the TIPM mounting bracket.
All of the current from the battery and the generator output enters the Totally Integrated Power Module (TIPM) via a stud on the top of the module. The TIPM cover is removed to access the fuses or relays. Internal connections of all of the power distribution center circuits is accomplished by a combination of bus bars and a printed circuit board. "
