Do passenger seats have weight sensors?
The front passenger’s advanced airbag system has weight sensors. However, if you do allow a child age 12 or under to ride in the front passenger’s seat, note that the system will automatically turn off the front passenger’s airbag if the sensors detect that the child is approximately 65 lbs (29 kg) or less.
Why does my car think someone is in the passenger seat?
In your vehicle, the occupant detection sensor detects when someone of the appropriate weight is sitting in the passenger seat. It then sends this information to the occupant detection module. Your problem is somewhere in this system, and my guess is that the occupant detection sensor or control module has failed.
What is a passenger seat occupancy sensor?
The Seat Occupancy sensor is a magnetically operated push button sensor with a simple push-fit clip mounting configuration, allowing the passenger safety system to determine the presence of an object or person in a seat.
Where is the airbag sensor in the passenger seat?
The location of airbag sensors differs from car to car. The most common location is inside the front bumper or fender, however many modern vehicles have several airbag sensors. They can also be found inside the engine bay, in the passenger seat area, or even in the rear or sides of the vehicle.
What does it mean when it says passenger airbag off?
Your passenger airbag will turn off if your passenger is: Light enough that the weight sensor detects that someone is occupying the seat, but not heavy enough that deploying the airbag is a wise idea. The sensor believes the person sitting in this chair is too light and deploying the airbag would be unsafe for them.
How do seat belt sensors work?
They cause the dash indicator light to light up or for the alarm to go off inside. The Reed Switch exists inside a seat belt buckle and determines whether or not the passenger is wearing their seat belt. The sensor inside the seat belt buckle also can light up the symbol resembling a person belted into their seat.
Why does my passenger seatbelt light keep flashing?
When you start the engine, the seat belt light will usually flash for a few seconds even if the seat belt is already secured. Sometimes, the seatbelt switch can get stuck or broken and the light won’t turn off. Clean out the buckle or replace it, if necessary, and everything should return to normal.
How does a seat occupancy sensor work?
When someone sits on the seat, the pressure sensor signals the occupant’s weight to the ECU. It reads the passenger’s seating position and determines if they’re wearing a seat belt. It also has a seat belt tension sensor that allows the OCS to interpret the pressure created when a child seat is fitted.
How does a seat position sensor work?
It detects how close to the steering wheel (and the air bag in the steering wheel) the front seat is positioned. Based on this information, the car’s computer determines whether to activate the air bag or not. In severe impacts, the air bag will be deployed no matter what the sensor says about the seat position.
