How'd you determine yours was an open circuit? Is there a way to read an airbag code?
If you can't tell, airbags are far from my interest area.

In your engine bay diagnostic port take a wire to use as a jump wire and plug into AB and TC port. Turn key on to ACC position. Your cruise control light will have a seizure. Your air bag light will go on for 6 seconds doing it's normal self check. It will then do 1 second blinks for however many times, rest 2.5 seconds, then blink 1 second interval again, then 4 seconds off. This tells you your two digit code, then you need to look that code up.
Example: blink 6 times, off 2.5 seconds, blink 4 times, off 4 seconds is code 64.
You may have more then one code. So after the 4 seconds off it may start the second code...
Example: blink 6 times, off 2.5 seconds, blink 4 times, off 4 seconds, blink 3 times, off 2.5, blink 2 times, off 4 seconds. Codes 64 and 32
So watch it until the first code repeats...
Once you start attempting to fix...disconnect negative terminal so you don't cause your bags to deploy while checking connections.
Once you fix the problem you need to clear the code. IT WILL NOT CLEAR ON ITS OWN!
Obd2 from dealer is best...make a friend in the repair section, bring him beer and hope he doesn't charge you...
Other wise with key in acc position using 2 long wire. Plug one into tc port and one into ab port. Starting with the tc port alternate grounding them on a body ground for 1 second intervals allowing .2 seconds between switching. Tc needs to be grounded 3 times and on the last one hold for a few seconds.
