My air bag light has come on three different times over the last six weeks or so. I took my car to the dealer but the light wouldn't come on when I took it in (just my luck). The light will come on when I start up my car, stay on for a few seconds, then blink on and off nine times at one second intervals. It repeats this process several times, and then the light stays until I turn off the car. Does anyone have any ideas on what could cause this? The light seems to come on after the car has been sitting out in the cold for several hours (about 15 degrees F). FYI, I have a 2002 ZTS with side air bags.
