1st off, does his scanner have the ability to communicate with air bag systems? If so, and there is no communication with the SDM, then you are on the right track in checking the fuses. You will need a schematic to locate which pins at the SDM are power and ground, and which are communication wires. I DON'T RECOMMEND AIR BAG REPAIRS BE DONE BY DIY'ERS!!! Have a reputable shop tackle this. There is only the one fuse in the I/P that powers the SDM.
