Removing Airbags / Measuring Resistance

[Duncan]

I am looking at removing an airbag but don't want to disable the whole system, so I need to know what resistance to add to trick the airbag computer.

The workshop manual and most of the internet say that if I use a multimeter to measure the airbag's resistance it will blow up in my face from the multimeter voltage. I do note my multimeter has a 9V battery so maybe it is close enough to 12v to do it....

This guy did it anyway, but I'm not convinced they removed the shorting bar because it reads 0 across the board.

This guy removes the shorting bar, measures it, and doesn't die.

Has anyone done this safely?

From memory i use a yellow fuse which i think is 2amp to simulate the correct resistance in my s15.

After watching myth busters I have a great deal of respect of air bags and simply do not mess with them - I am shit scared of these things.

Tread with caution mate because we do not want to have to visit you in hospital.

Duncan blowing himself up with an airbag on Christmas eve would be the most sau thing ever.

hmm, surprised no-one has done it, I would have thought the R35 guys would have had the issue. Mick thanks for the S15 info but I started with 2.7 ohms (S15 and 350z sized) but it didn't do the trick for the cima passenger bag which is what I need in this case.

In the absence of better information I'm doing it the slow and safe way and using a variable resistor to find what the car is happy with.

I seem to remember the NM35 guys using a 5ohm resistor on the seat airbags, and that is also what the r35 guys were using.

Not sure it will help, but it might be a ballpark to start in.
