How to Solve the Issue of Excessive Resistance in the Driver's Airbag?
2 Answers
The solution to excessive resistance in the driver's airbag involves removing the airbag and steering wheel to expose the airbag clock spring. By prying open the clip, you can replace it with a new airbag clock spring, then reassemble the steering wheel and all components in reverse order. Below is relevant information about airbags: 1. Function of Airbags: The airbag system is a passive safety protection system that, when used in conjunction with seat belts, provides effective collision protection for occupants. In the event of a car collision, airbags can reduce head injury rates by 25% and facial injury rates by approximately 80%. 2. Principle of Airbags: During a collision while driving, the airbag sensor receives the impact signal. If the impact reaches the specified intensity, the sensor activates and sends a signal to the electronic controller.
I've encountered this issue multiple times. The high resistance in the driver's airbag circuit can range from minor to severe, usually caused by a loose connector under the steering wheel or corroded wiring harness. Don't rush to DIY repairs—safety first, as the airbag system contains explosives with high accidental deployment risks. My advice: First, use a diagnostic scanner to read trouble codes and pinpoint the issue. High resistance indicates increased circuit impedance, possibly due to poor connections or aged wiring. Next, inspect the clock spring connection on the steering wheel—check if plugs are securely seated and contacts are rust-free. If cleaning doesn't resolve it, the airbag module itself may need replacement. Never ignore this fault—non-deployment during a crash is life-threatening. Park in dry areas to prevent circuit corrosion, and immediately visit a 4S shop with OEM equipment for professional diagnosis if the warning light appears.
