Just curious, are air bag codes stored in the PCM after only being triggered once? The reason I ask is that the air bag light stayed on in my '97 K1500 Suburban tonight for an entire drive cycle. First time I've ever seen that light in the 20+ years this vehicle has been in the family. I started it up later on in the night and the light stayed off, everything behaved as normal. Just wondering, if I hook up a Tech-2 or simliar scanner can I pull a code from that isolated incident? Alternatively, does anyone have any experience with an issue like this?
