U0140 code

[JanMan56]

Hey all, recently got a code reader for a different vehicle but out of curiosity I plugged it in to my 2014 Ram 1500 express and code U0140 appeared. I have no engine light on, I did have the airbag light on but the connector under the driver seat was loose. Fixed it and went off. Everything is working fine to my knowledge so I’m dumbfounded by this. Any suggestions?

It’s likely a stored code for lost communication with BCM. If there’s no lights on and everything works there’s no need to worry.
