Where'd you find that?
"P1604 Loss of IPC serial data"
Son-in-law's '03 GT got it. (the P1604)
Car runs fine.
I told him to take it to a parts store that'll plug in for free see if there's more info.
All he said what he was starting, and let the key go before it fully caught, and got the check engine light. Started the car but light stayed on.
