Your hose reel behind the steering wheel is probably going bad. My SRS light would come on when the wheel was turned in certain positions. Then one day it stayed on forever. Check for continuity between the two connectors and it was a goner. Reel is expensive as all hell!!!!
I hope this is not your problem. Does your cruise still work? Mine died a few weeks after the light came on. What made me finally fix it was when the horn died. All 3 are controlled through the reel.
