I got me a 07 ranger and I got these codes relating to the airbags. Anyone got any clue on what these all mean? And for what it’s worth my alternator is good. Could this have anything to do with the aftermarket speakers and radio I installed recently?

 

Does your passenger airbag light work?

I think B1884 means that light is burned out.

 

my passenger airbag light turns on when I have the key in the on position and if I start the truck it’ll turn off after just a second and then the airbag light comes on.
