I checked INPA for light module fault codes and there were none. When an LCM fails, does it typically throw faults?

I guess the next thing I will check is the taillight wiring loom and see if I’m getting voltage there and if not try and figure out which pins should be showing power from the LCM. Any other suggestions?
