AIR BAG LIGHT

2004 GMC Envoy

Electrical problem
2004 GMC Envoy 6 cyl Four Wheel Drive Automatic 110000 miles

My 2004 GMC envoy air bag light comes on and the dealer says it was code b1000 ecu malfunction. How do I reset it or do I have to get a new air bag module unit. Is it a problem to reset it.
