* Faulty Crash Sensor: These sensors detect impact and trigger airbag deployment. A malfunctioning sensor can trigger the light.
* Faulty Airbag Control Module (ACM): The "brain" of the airbag system. This module can fail due to age, electrical issues, or even minor impacts that didn't deploy the airbags. This is often the most expensive repair.
* Faulty Wiring or Connectors: Corrosion, damage from rodents, or loose connections in the wiring harness can interrupt the system and trigger the light. This is a common problem, especially in older vehicles.
* Faulty Airbag(s) or Seatbelt Pretensioner(s): A problem with the airbags themselves or the seatbelt pretensioners (which tighten the belts in a crash) can cause the light to illuminate.
* Low Battery Voltage: In some cases, a low battery voltage can cause the light to come on. This is usually accompanied by other electrical issues.
* Clock Spring (Spiral Cable): This component allows the steering wheel to turn while maintaining electrical contact for the airbag. A worn or broken clock spring is a frequent cause of airbag light issues.
* Seat Occupancy Sensor (in some models): Problems with the sensor that detects if a passenger is in the seat can affect the passenger-side airbag system.
To diagnose the problem accurately, you need a professional-level scan tool. A standard OBD-II code reader may provide *some* information, but it won't be as comprehensive as a tool specifically designed for the SRS system. Taking your Jeep to a mechanic specializing in automotive electrical systems or a Jeep dealership is crucial. They can use a scan tool to read the diagnostic trouble codes (DTCs) stored in the ACM, which will pinpoint the exact cause of the problem.
Ignoring the airbag light is extremely dangerous. If the system is faulty, the airbags may not deploy in a crash, potentially leading to serious injury or death. Get it checked out as soon as possible.
