Airbag sensors are actually small electronic pieces that sense when an accident has taken place. They are designed to respond to circumstances such as increased pressure resulting from a collision and sudden stopping.Know More
Airbag sensors can be used to detect how many people are in the vehicle and measure wheel speed, impact and brake pressure. The airbag control unit is usually built into the front section of the cabin. The unit is programmed to study the information that it receives in order to activate seat belt locks, airbag deployment, automatic door locks and other safety measures.
The two different types of airbag sensors are mechanical and electrical. Some electrical sensors use electromechanical "bauble and ball" mechanisms designed to release a ball from a magnet, which rolls into a tube before hitting a switch and completing an electrical connection. Mechanical sensors are designed to work independently from their electrical counterparts, and they utilize a firing pin to activate a compact explosion after an accident occurs.
One difference between the two different types of systems is that mechanical sensors can't be shut off after the battery has been disconnected the same way that electrical ones can, since mechanical sensors don't require a power source.Learn more about Car Parts & Maintenance
Parking sensors use ultrasonic or radio waves that reflect off of objects behind the vehicle to let the driver know how close they are to hitting the object by emitting a beep as a warning. They allow the driver to be more confident while parking and driving in reverse.Full Answer >
A weight distribution hitch distributes the weight nearest to where a trailer connects to a towing car to prevent an imbalance in weight from causing an accident. The hitch minimizes the danger caused by a weight imbalance by distributing the weight that is pushed on the rear axle of the towing vehicle to the front axle and any axles with which the trailer is built.Full Answer >
To know if your airbag has been recalled, visit the website of the car manufacturer, and use the recall lookup tool by providing the car's vehicle identification number. A product recall check provides information about the car's recall history, including safety recall information specific to your vehicle.Full Answer >
The airbag light comes on when the backup battery is drained or damage has occurred to the clock spring or the airbag module. Because the light can have many causes, a technician must diagnose the problem if the light stays on.Full Answer >
