Air Bag repair question: Flash Code is 3-2

“Driver Air Bag Circuit Resistance High or open.”

Doing research, suggestions are a sensor in the circuit, perhaps
behind the front grill. These parts are hard wired in the air bag
system.

Another suggestions is the coil spring in the steering column which
indicate this is the problem in 95% of the cases for this code flash.

I can replace the coil spring – following ALL the warnings to disarm
the air bag and following my research.

Would you think it is the coil spring as the sensors have not been
damaged by an accident?

A coil spring is ~$70 vs $250- $300 for shop repair.

A Rotunda Air Bag Simulator 105-00010 is a 2 ohm resistor that
simulates an air bag connection. That would be another DIY cost if in
90-95% of cases it is just the coil spring.

Thoughts?
I would pretty well rule out the sensors at the bumper. Clock spring
problems are pretty common. Make sure to follow ALL safety warnings
and procedures. With the air bags removed you can check continuity
safely with a multimeter.

Clare,

Another question. Is the Rotunda Air Bag Simulator 105-00010 2 ohm
resistor that simulates an air bag connection necessary?

I've read of two places to connect it. Both make sense. One at the
steering wheel and one below the dash. I'm the student
If you connect below the dash and the code goes away, and you install
it at the wheel and it doesn't, you KNOW the clock-spring is the
problem. You can buy a 2 ohm resistor for less than a buck, or the
Rotunda tool for about $40. The advantage of the real tool is it has
the right connector. Go to a body shop or wrecker and beg a discharged
air-bag, snip off the connector, and make your own tool??
