Can anyone identify what program ford flashed to the PCM on my truck? The sticker says

Reprogrammed PCM
407A-12A650-GRA
06-01-2006

Just curious what was done to the truck last June.

Thanks!

 

Ford doesn't tell us what calibrations are specifically supposed to do. There's a couple different instances where your PCM would have been reprogrammed, if they did the idle vibration repair with new motor mounts, maybe they replaced the TPS or throttle body assembly, maybe they did it just for CYA, there's no way to tell for sure.

That sticker should read 4U7A, not 407A.

 

Hmm okay, well I didn't figure it was anything major, just wondering exactly what it was. Probably no big deal.

Thanks for the reply and yes I think that is "U" but the hand writing is pretty bad.
