How do I test front crash sensor 2005
 

Airbag light is on. Scanner gave me code B0101 for front sensor. how do I test sensor with meter?:confused:

I would check the wiring just to make sure nothing is unplugged, corroded, etc.

I say when in doubt, replace it. Up for a junkyard run?

I was having problem with radio draining battery. While measuring for parasitic drain and removing fuses one by one. After battery drained a third time, i put different radio in and the airbag light appeared. Buick dealer mechanic put scanner on it and he said he could not reset it because of the code B0101. Any ideas?
