how to fool car to eliminate airbag light?


Recommended Posts

2004 986S dedicated track car

I am preparing my car for a full cage which will go in later this summer. I will need to install a removable steering wheel to facilitate getting in and out once the door bars are in. Once the full cage is in, I will likely completley disable the airbag system. But, in the interim, while using the aftermarket wheel without an airbag, I'm wondering if I can fool the car into thinking the driver airbag is still there, and keep the passenger airbag active?

I measured the resistance across the two pins on the driver's side airbag at .2 Ohms. Can I wire in a resistor in place of the airbag, thus fooling the car? Would it be a resistor of .2 ohms? and while I don't know much about resistors, I do know there is a power rating to them...anyone know the power rating needed?

Resistors are rated in Ohms as you said. They are color coded with stripes and if you know (for sure) the rating your local Radio Shack or electronics part supply could tell you which one you need. I agree with wvicary that the airbag system is too dangerous to mess with if you don't know exactly what you are doing.

I vote for not putting the removable steering wheel in until the day before you put the cage in.

Some one will want your three spoke wheel and airbag, so you don't want to blow the bag and possibly your hearing out!!

Do not test the airbags with an ohmmeter, as doing so might possibly flow enough current to deploy the bag. That is why airbag electrical connectors are typically equipped with a shorting bar which jumps both terminals together when the connector is unplugged. The shorting bar is why you measured only 0.2 ohms when you tested it. Airbag squib resistance is probably in the neighborhood of 2 ohms. You could try a 2 ohm resistor, but I wouldn't do so.
