However, some common causes include:
* Faulty Crash Sensor: These sensors detect impacts and trigger the airbag deployment. A malfunctioning sensor can trigger the light.
* Problem with the Airbag Control Module (ACM): This is the "brain" of the airbag system. A damaged or faulty ACM is a common culprit and often requires replacement (a costly repair).
* Wiring Issues: Damaged, frayed, or corroded wiring in the airbag system can cause the light to stay on. This can be anywhere in the system, from under the seats to the steering wheel.
* Faulty Airbag(s): Although less common, a problem with the airbag itself can trigger the light.
* Seatbelt Buckle Switch: A problem with the seatbelt buckle switch can sometimes trigger the light.
* Clock Spring (Spiral Cable): This is a component in the steering column that allows for electrical connections while the steering wheel turns. A malfunctioning clock spring can affect airbag deployment.
* Low Battery Voltage: In some cases, a very low battery voltage during a previous incident can cause the light to stay on.
* Previous Accident: Even a minor accident can damage components of the airbag system, even if visible damage isn't apparent.
To reiterate: A mechanic needs to use a diagnostic tool to read the specific fault code stored in the airbag control module. This code will pinpoint the likely cause of the problem. Simply guessing based on general information is dangerous and could lead to further damage or injury. Get it checked professionally.
