    Cool Fix for Airbag light (airbag bypass)

    I recently purchased a used 04 ZHP sedan with 115,000 miles on it. The owner told me that it had an intermittent airbag light that would come on after someone sat in the pass. seat and the light would clear randomly. I got him to take $200 off the asking price. The previous owners records showed that the passenger seat occupancy mat was replaced at 49,000 miles.

    I didn't want to take the whole seat apart so I installed a Passenger seat occupancy mat bypass module.


    Installation consisted of cutting the pass airbag mat wires loose and splicing the bypass module. After this was done the airbag light has not come back on. My airbag light was off when I installed the bypass. The airbagRX website states you may have to have a dealer clear the airbag light.

    I purchased the bypass at http://www.airbagrx.com/

    I hope this helps anyone with this problem.

    I've considered doing this too, but have yet to find a definitive answer on whether the airbag will always deploy or not. I think the bypass module's electronics emulate the resistance of a passenger so the airbag will always be deployed; does anyone know for certain?

    No- bypass tricks the computer into thinking someone is sitting there, so it fires no matter what.

    Looks like a pretty good option for someone who doesn't feel like tearing the seat apart.

    Bookmarked the website for the future.

    Nice find, Blue- thanks for posting.

    Correct. According to their website the bag will always fire regardless of occupancy.

    Perfect! Now to dig up the DIY to put together the correct resistors & other bits. (I always love soldering my own electronics. )

    The "con" to this is that in any accident you have....BOTH airbags will go off.......vice just the one side. Your car always thinks someone is sitting over there in the passenger seat. The occupancy sensor is there to save a $3k airbag, should no one be sitting there, when you get into an accident.

    I recommend fix the problem correctly...in the long term.

    A little off topic, but do our passenger airbags have the weight sensors that manage deployment if a kid is in the passenger seat?
