Check Engine Lught / service airbags

[Ram FF]

2021 Rebel 5.7 etorque 4 months old 6k miles.

So, I took my door apart today to give it some sound treatment for my upcoming audio build and now I have a Check Engine light and Service airbags message. I did unclip the wiring between the door and cab during this process. Does anyone know what could have caused this and where do I go from here?

Disconnect battery for 30 minutes, see if that clears the code.

More than likely there's some module or other in the door, and when you disconnected things, it lost communication on the bus. So now the airbag system is deactivated and awaiting diagnosis, and the check engine light is on out of sympathy. I used to run into stuff like that all the time at Toyota --- 5 or 6 different systems all throwing useless codes because one system is not talking to the rest.

Go to the parts store and have them clear codes. Or try the battery disconnect. After the disconnect, it's probable that things will be nutty for a few hours - lost XM radio is common - but it'll all come back online eventually.

That worked. Got better response out of the truck too, with that ECU reset.

The old IT maxim holds true. When all else fails, reboot! LOL
