I have a tiv keeps shutting down on a 122 error I’ve replaced
Dz1 and DZ2 LU and LD pmi modules, as well as DZ1E and DZ2E modules. New DZ1 and DZ2 relays as well as a new leveling transducer. The car is still shutting down. It has even logged the fault just sitting at the first floor with the in car stop thrown so it doesn’t even have to be running to log the 122. I’m starting to suspect traveler wires or possibly a bad pmi card any other thoughts?
