The airbag light came on for the first time this afternoon. Stopped the car and ran in a store, started it back up and it went off. Stopped at another store, it came back on. Stopped again and it went off. I read online that it might be the spiral cable. I hooked up Techstream and found codes B0101 and B0111. Searched here and found these descriptions for them. I will make sure the side bag connector is tight tomorrow, but from the descriptions below it looks like the airbag sensor assembly is the only possible culprit. Anyone know the part number for a 99? Any thoughts on the situation?

B0101 - Open In Driver-Side Air Bag Module Squib Circuit
This DTC could be caused by a open in D+ (Yellow/Black wire) or D- (Yellow wire) in squib circuit, squib malfunction, spiral cable malfunction or air bag sensor assembly malfunction.

B0111 - Open In Right-Side Air Bag Module Squib Circuit
This DTC could be caused by a open in Yellow/Red (circuit SFR+) and Yellow/Green (circuit SFR-) wires in side air bag squib circuit, side air bag squib malfunction or air bag sensor assembly malfunction.

 

Start with the basics, disconnect the battery for 15 mins, open the connectors, clean them with a pencil eraser and contact cleaner, and re-seat them and clear the codes.

Sometimes the connection is intermittent especially when you slide the chairs back and forth.

 

I think it may be something simple. That one day is the only time the light has come on.

 

Did you slide across the drivers seat and pull the leather when you got in? I did this once and the light came on.

 

i have this intermittent issue.
seems to be related to seat belt tensioner...just fyi.

 

Light came on again a few days ago. Today I pulled the front seats and sprayed the connectors with contact cleaner. Hopefully that solves the problem, although they didn't really seem loose or dirty.
