SRS Air Bags
Driver and Front Passenger Occupant Classification System (Some Models)
The Driver and Front Passenger Occupant Classification System reduces the possibility of injury due to the deployment of the driver air bag and the front passenger airbag by determining the deployment energy of the driver air bag and whether or not the front passenger airbag should be deployed based on the driver seat slide position sensor and the front passenger seat weight sensor.
Driver Seat Slide Position Sensor
Your vehicle is equipped with driver seat slide position sensor as a part of the supplemental restraint system. The sensor is located under the driver seat.
The sensor determines whether the driver's seat is forward of or behind a reference position and sends the seat position to the diagnostic module (SAS unit). The SAS unit is designed to control the deployment of the driver's air bag depending on how close the driver's seat is to the steering wheel.
During an impact of moderate severity, the driver's air bag deploys with lesser energy, whereas during more severe impacts and when the driver's seat is behind the reference position, it deploys with more energy.
Front Passenger Seat Weight Sensor
Your vehicle is equipped with a front passenger seat weight sensors as a part of the supplemental restraint system. These sensors are located under both of the front passenger seat rails. These sensors determine the total seated weight on the front passenger seat and monitor the seat belt buckle for the front passenger seat. The SAS unit is designed to prevent the front passenger front and side air bags and knee air bags, and seat belt pretensioner system from deploying if the front passenger air bag deactivation indicator light illuminates.
To reduce the chance of injuries caused by deployment of the front passenger air bag, the system deactivates the front passenger front and side air bags and knee air bags, and also the seat belt pretensioner system when the front passenger air bag deactivation indicator light illuminates.
Driver and Front Passenger Buckle Switches
The buckle switches on the front passenger seat belt detect whether or not the front passenger seat belt are securely fastened and further control the deployment of the air bags.
