Problem overview

Some Cadillac STS owners report experiencing issues when the service airbag light illuminates, indicating a fault detected by the airbag/restraint control module. This warning may be triggered by faulty airbags, including the steering wheel, knee bolster, or side airbags. Additionally, owners have noted that sensor or wiring issues, such as faults in impact sensors or loose connections, can also cause the light to activate. Some owners find that jiggling the wire connector under the front seat may temporarily resolve the issue, suggesting a possible connection problem. However, if the light persists, it is recommended that owners seek professional assistance from a certified mechanic or dealership for a thorough diagnosis. Promptly addressing the service airbag light is essential for ensuring the vehicle's safety features are functioning properly.
