Mine just started blinking in twos. Blink blink pause. Blink blink pause. This is the red light on the dash, above and to the left of the green light that shows that the headlights are on. The passenger airbag light (to the right of the radio) is not on.
On the flashes, there may be two short flashes then a pause, then two longer flashes then a pause. Or maybe they are all the same - just as I was checking it out I was on the interstate and my TPMS went off, the good news is that it works fine, there was a one or two second beep with the light. I didn't feel any steering issues so I pulled off at the next exit which was a mile ahead and pulled onto a side road, under a street light. My driver's side rear tire was completely flat in less than a minute. Turned out that I ran over some piece of metal on the interstate, I could feel the air coming out of the tire. This metal piece was about 3/4" long, like somebody jabbed a knife in the tire and broke it off. Weird. I have "road hazard warranty" on the tire through Discount Tire, I'll get it taken care of tomorrow at minimal cost.
And just a reminder - check the pressure in your spare. Mine was at 15 psi, it is supposed to be at 60 psi. I drove at 30 mph for a couple of miles to the next gas station, it was fine but luckily there was a station that close.
Any ideas on the airbag lights?
