Just did some work on my car this past few days.
Changed headlights, put in a new ac line from firewall to drivers headlight, line broke at condenser when I took radiator out in the winter.
I go to start the car and there is nothing, no fuel pump priming nothing. Scanned for codes and this is what I’m getting. Lights n dash windows and all that work.
B2750-02 & 04. Pass key data communication failure
B3875-02 & 04. Manufacturer defined??
U101 lost communication with TCM.
Any suggestions where to look?
