If you have the 4 post FICM (remove little cover on top below are 4 or 7 screws). I do not know if this works for 7 screw ficm. Check the voltage on the screw closest to the fender and ground if less than 45 volts engine running you can repair it yourself and no reprogramming needed (dont touch probe from screw to the case).
Remove FICM from truck. Remove the following; small cover on top of ficm, 4 screws that are under cover, 6 screw on other side holding case together. Split case. Re solder 16 places circled in pics. Put back together and check voltage.

Well I guess if you have a bad FICM anyway what do you have to lose?
