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.

It was the control module. Last time told connector under seat had high resistance and they repositioned wire to "remove tension"

Do you mean a new control module solved the problem?

Yes, new control module on Nov. 2008 lasted till Dec. 2008 when code B1346 found & cleared. Lasted till April 2010 when code B 1378 found and they repositioned wire for air bag connector under the drivers seat, then cleared code. Now airbag light on all the time again. Tried jiggling wires, pushed on connectors-nada. Thanks for assist.

Oh, I get it. I thought you solved the problem THIS time with a new control module.
There will be another code in the control module now. Have that read. It will point you to the right circuit. The person who reads the codes should be able to show you where the suspect circuit located and how it works.

Is it possible you would have to replace the airbag?
