Yes they do. My 06 Dakota has 4 weight sensors in the passenger seat.
The passenger seat has a weight sensor which automatically turns the airbag 'on' at a certain weight. If there isn't enough weight in the seat, the system determines that there is no passenger in the seat and leaves the airbag OFF. The weight sensor can also cause the passenger airbag to deploy with less force if it determines the passenger is small and might be injured by a full-force deployment.
The seat should have a sensor inside that when enough weight is in the seat it will automatically turn on the airbag system for the passenger.
No. The Magnum has a sensor in the passenger seat that detects if there is sufficient weight to turn the airbag on. With the vehicle running, sit in the driver's seat reach over and push down on the passenger seat. You will notice the "Passenger Airbag OFF" light right above the stereo going off and on.
It takes 90 pounds to turn the Chevrolet passenger airbag on. The airbag will not engage if the 90 pound weight limit is not met.
In most newer cars, no. Older cars may not even have an airbag for the passenger. In most cars that do however, there is a weight sensor in the passenger seat that turns the airbag on only if there is someone heavy enough in the seat. This prevents the airbag from deploying if no one is in the seat and also prevents it from going off if there is a small child in the passenger seat.
The passenger airbag is on a Weight Detection System. The only way to enable it is to Bypass the weight detector.
Well, it depends on the model year of the Corvette. On most C-5 models there is a switch in the passenger glove box. Just stick key into that switch and turn to off. On newer models, there are pressure sensors in the passenger seat to determine the weight of the passenger, I think the weight trigger is 80 pounds. If weight is under 80 pounds, say for a small child, the airbag will be off. If weight is over, the airbag will be on.
This means that the minimum weight has been met on the passenger seat for the airbag to be turned on.
The front passenger seat has a sensor built into it and is always on unless a weight between 9 and 45lbs (maybe slightly different) is placed on the seat. This is in case you put a child safety seat on the front passenger seat so as not to deploy the airbag in a collision. The sensor is also intelligent and will vary the deployment depending on how heavy the front passenger is so as to minimize any injury the airbag could cause.
The Ford focus does not come equipped with a passenger airbag on off switch. The airbag will not engage unless certain weight requirements are met.
That light either indicates that the airbag is on/off. The passenger seat has a smart sensor within it which senses the weight and position of what/who is in the seat. Coupled with/without seat belt usage it will turn on/off depending on exact situation in that seat as to function or not based on it's calculated determination.
The passenger airbag weight system needs to be recalibrated.
