By "module" do you mean the air bag assembly itself on the steering wheel or the control module? All air bag computers have a memory and record diagnostic fault codes. This is especially useful for finding intermittent problems. They will lead you to the circuit or system with the problem, not necessarily the defective part. They will also differentiate between the circuit under the seat which can be for a weight sensor, a seat belt buckle switch, or a seat belt tensioner. The place to start is by having the codes read. Due to the age of the car, there is a pretty good chance many independent repair shops can do that for you with their aftermarket equipment. Otherwise the dealer can do that for you. Hyundai is one of the more customer-friendly manufacturers along with Chrysler and Toyota, so special software needed is easier for the independent shops to get.
