My car was doing that too. I got under the seat and unhooked the sensor.
Guess that's what I'll do.
Also, I'll still use the 180°, it's already in the car. I do almost all city driving, and in 95° michigan summer temps, I'm sure it will be over 195. But if I notice it not getting near full temp enough I'll swap it out, I'll pay attention to the gauge.
if its off and on, that could be it. if its on all the time, its that module, or a clock spring 99% of the time. if not a dirty yellow plug somewhere.
a scan will tell you. auto body shops have this scanner, as they re set airbags a part of their daily job. mine was a clock spring when i had it scanned, but the car got flooded after the scan, changed the clock spring, and still on, swapped the module, and off it has been since.
If its going off while I am unbuckled, thats my own fault. It was going off when I was buckled.
I still have the damn random air bag light though.
