It's definately a remanufactured FICM off a pre 9-29-03 build engine. My copy of the dealer service order states the following:
Replace Inejector Drvier Module (IDM) / Fuel Injector Control Module
Part number: 4C3Z-12B599-AARM
Description: Process Asy Remanufactured
Just thought it was somewhat strange that they put a pre 9-29-03 build FICM on my truck, as it is a post 9-29-04 (updated 04) engine. I was also under the assumption that 04 engine updates included changes to the FICM. I have no idea what callibration level is in the reman FICM. Guess the dealer would have to look it up on the WDS.
