After a calibration flash on a 07 Charger RT, it will no longer start. Throwing U0100 code, and says no communication with PCM. It flashed the computer without issue, and I have flashed it several times in the past with this calibration.
Can anyone offer some suggestions to help me try to recover this thing? I have disconnected the battery for a few hours, and checked all of my fuses. Still no luck.
have you tried to read the ecm since it wont start?
same issue on a 2014 cadillac ats cant even read the vin off the car now
my duramax did the same thing. ended up being the BCM went out when I flashed the PCM
so $600 later and a new BCM I read the PCM and my tune was on there! don't know what happened but it sucked having to pay that kind of money....
Did you have to do the relicense/credits again after your BCM failed?
Was anything ever figuted out OP? Im currently in the same boat with an 06 Hemi Charger.
