1) Faulty SRS Control Unit: The SRS control unit is responsible for monitoring and controlling the airbag system. If it's faulty, it may cause the SRS light to stay on.
2) Faulty Sensors: There are several sensors in the airbag system, such as the impact sensors and seatbelt buckle switches. A faulty sensor can trigger the SRS light to stay on.
3) Wiring Issues: Broken wires or loose connections in the airbag system can also cause the SRS light to stay illuminated.
4) Clock Spring Malfunction: The clock spring is a device that allows the steering wheel to rotate while maintaining electrical connections. If the clock spring is faulty, it can disrupt the signals between the steering wheel and the SRS system, causing the SRS light to stay on.
5) Airbag Module Failure: The airbag module, also known as the inflator, may have a fault or defect, causing the SRS light to remain on.
It's important to have the SRS system diagnosed by a qualified mechanic or technician to determine the exact cause of the SRS light staying on and ensure proper repairs are made to restore the functionality of the airbag system.
