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
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 >
"SRS" is the acronym for a supplemental restraint system, more commonly known as a car's airbag system. Considered a passive restraint system, the SRS is intended to be used in conjunction with seat belts rather than as a replacement.Full Answer >
The SRS warning light is the supplemental restraint system warning light, which is also called the airbag system warning light. In most cars, it should appear for 1-5 seconds when the car is started. This brief lighting indicates that the system is self-testing, but if the light stays on, this is an indication that there is something wrong with the system and it is disabled.Full Answer >
Before an airbag light can be shut off or reset, the airbag ECU must be cleared, according to CarsDirect.com. The website recommends removing the airbag ECU and taking it to a car mechanic who can run a diagnostic on it and either repair or replace it. This type of work should only be handled by a professional, as an improperly repaired airbag may not deploy properly, which is extremely dangerous.Full Answer >
