OBD2 port will pull codes but will not show live data
Out of nowhere my OBD2 port randomly stopped giving me live data. it will pull codes and clear codes without issue but any live RPM or coolant temperature data etc that used to give it will not anymore. I'm trying to diagnose cooling issues. Does anybody know what could be causing that part of the OBD Port not to work. This is a 98

There are a few other threads that suggest CAB issues can mess up all communication.
