You will have to be very careful!!! There have been cases where the airbag lights come on because of an internal computer problem. If you go to your dealer, or maybe a local shop, they will have to hook it up to a computer to determine the problem. Not to get too excited, but some people have had the bag actually deploy, so I usually make that known to anyone I help with an airbag light. Hope all goes well, and please be safe.

Just behind right rear tire up in the wheel well. Air inlet is inside right rear quarter near the accessory inflator. Compressor runs 3 lines one for the accessory inflator and one for each air bag.
THere are also 2 sensors, one on each trailing arm that senses load and then raises and lowers accordingly.

it may need cleaned, they get carboned up as do the throttle plates inside the throttle body. use carb cleaner and a soft rag to wipe clean. do not use a wire brush. also check for vacuum leaks, spray carb clean around manifold an see if idle changes

This code indicates a problem with the fan clutch, the speed it is running is not the speed it was commanded to run/ The fan clutch assembly needs replacing.
