A bit of speculation here:
I think all of these are in reference to what Ford calls the PCM (powertrain control module), which is the ECM (engine control module) and transmission control module combined. We have a PCM behind the passenger kick panel.
When they say Body computer/module, that's a bit peculiar, because we don't have one of those to my knowledge.
BCMs are common in newer cars and usually combine several modules into one that used to be individual modules in older cars, e.g., turn signal flasher, daytime running lights, auto lights, alarm, locks, delayed accessory power and countless other things. Body generally referring to anything
other than powertrain.
Either they meant the PCM and just worded it funny, or they were referring to some other module, relay block, or junction block. Hard to say.
PCM issues don't seem uncommon. My car was on its second PCM when I bought it, and I have since replaced that with a junkyard unit (as part of my fix for a crankshaft sensor code, though wiring repairs may have been the main fix, and I keep the other PCM as a backup).
@Rodeo Joe is also on his second PCM.
All in all, these Carfax items wouldn't concern me. There were issues, and they were fixed.
More important is that the car passes inspection now.
