1. Faulty Seat Belt Sensor: The seat belt sensor is responsible for detecting whether the seat belt is fastened. If the sensor is faulty or damaged, the airbag light may remain on.
2. Loose Connections or Wiring Issues: Loose or damaged wiring can disrupt communication between the airbag sensors and the control module, preventing the airbags from deploying properly. This can cause the airbag light to remain illuminated.
3. Faulty Airbag Module: The airbag control module is responsible for managing the airbag system and triggering airbag deployment in the event of a collision. If the module is faulty or damaged, it may prevent the airbags from functioning correctly and cause the airbag light to stay on.
4. Impact Sensor Malfunction: The impact sensors detect the force of an impact and trigger the airbag deployment. A malfunctioning impact sensor may fail to detect an impact, preventing the airbags from deploying and causing the airbag light to stay on.
5. Clock Spring Issue: The clock spring is a component located in the steering wheel that allows for the deployment of the driver's airbag while still enabling the steering wheel to rotate. If the clock spring is damaged or faulty, it can cause the airbag light to stay on.
6. Software Issues: In some cases, software glitches or errors in the airbag control module can cause the airbag light to stay on even if the system is functioning properly.
To accurately identify the cause of the illuminated airbag light, it is recommended to have your vehicle diagnosed by a qualified mechanic or a Subaru dealership. They will be able to use diagnostic equipment to scan the airbag system for faults and determine the necessary repairs.
