Does your truck have an aftermarket head unit?

parking brake?

[broncobuyer]

no i dont have anything aftermarket on it. and the parking brake does not seem to be engaged

Sometimes if the parking brake pedal isn't all the way uo it will still beep.

when u turn the key on does the airbag light work?

[cchase]

airbag light burnt out, thats what mine does!

[broncobuyer]

yup, you guys are right on. i just ran out and scanned it and had two codes, lamp airbag warning indicator ckt open, this would probably be from a burnt out bulb. the other is PAD sw warning lamp inop, anyone know what that code is for or how to fix it?
