There are a few ways to address this:
* Professional Diagnostic Scan: The best and safest method is to take your car to a qualified mechanic or auto parts store (like AutoZone, Advance Auto Parts, etc.) that offers OBD-II scanning services. They have the proper tools to read the diagnostic trouble codes (DTCs) stored in the airbag control module (ACM). This will pinpoint the exact problem. They can then clear the codes *if* the underlying issue (the steering shaft replacement) is the only problem. If other problems exist, they will be identified.
* Professional-Grade Scanner (If you're mechanically inclined): If you have access to a professional-grade scan tool capable of communicating with the airbag system, you might be able to clear the codes yourself. However, *be extremely cautious*. Improperly working with the airbag system can be dangerous.
Important Considerations:
* Clockspring: The clockspring is a crucial component in the steering column that allows the airbag and other steering wheel controls to rotate with the steering wheel. If you disconnected this during the shaft replacement, it's *very* likely the source of the code. It may need to be properly reconnected or even replaced. Make absolutely sure all connections are secure and that there is no damage to the clockspring or its wiring.
* Other Connections: Double-check *all* the connections related to the airbag system that you disconnected during the repair. A loose or improperly seated connection will trigger the light.
* Battery Disconnect: Before attempting any of the above, you might consider disconnecting the negative battery terminal for at least 30 minutes. Sometimes this will reset the system, but it's not reliable and it's best to pinpoint the actual problem using a diagnostic scanner.
Do not attempt to "reset" the airbag light without properly diagnosing the cause. Ignoring the light is extremely dangerous, as it could mean your airbags won't deploy in a collision. A professional diagnosis is highly recommended.
