The seat belt sensor is part of a vehicle’s passenger safety system. It detects when the seat belts in the vehicle are fastened while a passenger is sitting on a seat. If the seat belt isn’t fastened over a rider, then the seat belt sensor will trigger the seat belt warning light while playing a pinging sound.
The seat belt sensor is typically found inside the vehicle’s airbag supplemental restraint system (SRS) module, which can be found in the kick panel, center console, behind the steering wheel, or under the radio.
The location of the SRS airbag module, and subsequently location of the seat belt sensor, often depends on the vehicle’s make and model. For instance, the 2007 Chevy Silverado has two SRS airbag modules underneath the vehicle behind a plastic splash guard. Meanwhile, 2012-2019 Ford Fusion models have their SRS airbag module in the middle console.
Tips on How to Access the Seat Belt Sensor
It’s best to check your owner’s manual to find your SRS module. You might have to check beneath the driver and passenger seats or the center of the dash on the floor. Most GM vehicles will have it under the driver or passenger seat.
