Here are some of the potential causes of an airbag light coming on:
Faulty airbag sensor: This is one of the most common causes of an airbag light. The sensor may become damaged or misaligned, triggering the light to come on. Replacing a faulty airbag sensor can cost anywhere from $100 to $400, including parts and labor.
Airbag module problem: If the airbag control module detects a problem in the system, it will activate the airbag light. Faulty components, corroded wiring, or software issues can all cause the module to trigger the light. Diagnosing and repairing an airbag module problem can be significantly more expensive than replacing a sensor, ranging from $500 to over $1,000.
Clock spring malfunction: The clock spring is a device that connects the steering wheel to the vehicle's electrical system. When the clock spring becomes dirty or corroded, it can cause the airbag light to come on. This repair usually involves removing and replacing the clock spring, which can cost around $200 to $700.
Wiring issues: Broken or frayed wiring related to the airbag system can also trigger the airbag light. Repairing damaged wires or connectors may cost anywhere from $100 to several hundred dollars, depending on the extent of the problem.
These are just a few of the possible causes of an airbag light being on. Without knowing the specific issue with your car, it's challenging to give an exact cost estimate. If the airbag light is on in your vehicle, it's recommended to have it diagnosed by a qualified mechanic or dealership service center to identify the specific problem and receive an accurate cost estimate for the repair.
