Airbag code 42 after vandalism
 

I have a 2006 Ford e150. My van was broken into and the vandals partially removed the front passenger seat air bag cover in the dash. Why I don't know. I was able to reseat the cover but now I have a code 42 reported from the flashing air bag light on the dash. I know that this code is supposed to tell you that there is a problem in the front hood sensor circuit. Is there any way that the removal of the plastic cover could trigger that code and if so how do I fix it? Thanks Tony
