Dodge Charger 2006
Airbag light is on, horn does not work, although cruise control does work.
Mechanic gave me an Airbag code B1B02 and a Check Engine code P0420.
Dodge wants to charge me $150 per diagnostic (one for the airbag and one for the check engine) but I figured from the googling I done, the airbag is likely to be the clockspring because of the fact the horn doesn't work as well. But I wanted to confirm that, because the cruise control works, does that rule out the clock spring being the issue?
Also, any suggestions for the P0420 code?
