What are the reasons why the airbag cannot deploy?

[MacAthena]

The reasons why the airbag cannot deploy are: 1. The manufacturer's preset deployment conditions are not met. Different car manufacturers have different settings for airbag deployment conditions, and the airbag will not deploy if the triggering threshold is not reached; 2. The vehicle collision occurs at a certain angle that fails to activate the collision sensor, such as impacts at the headlight area, front wheel position, or collisions with small objects; 3. The airbag warning light remains illuminated without timely inspection and repair; 4. Seat covers may cause side airbag failure; 5. The airbag has reached the end of its service life. The airbag consists of an inflation sensor and an inflation system, and its functions are: to protect occupants by reducing contact with interior objects, more evenly distributing head and chest collision forces, absorbing occupant kinetic energy, thereby supplementing the effectiveness of seat belts.

I've been driving for years, and the issue of airbags not deploying is quite common. The sensors are the most prone to problems, such as being clogged with dust or damaged, failing to detect collision signals. Wiring aging is also common; if wires break or connectors loosen, the current can't pass through, and the airbag won't respond. There's also the issue of control module failure—this acts like the brain, and if it's damaged, the entire system fails. Airbags also won't deploy if the collision force isn't sufficient; their design is based on impact force, and if it's too small, the impact won't trigger them. Poor maintenance has a big impact—if the battery is low or the voltage is unstable, the system shuts down. I must remind you, this is no small matter; driving safety depends on it. It's recommended to regularly visit a repair shop to check the circuits and sensors, not wait until something happens to regret it. When cleaning the vehicle, also pay attention to the sensor locations.

Working in an auto repair shop, I often encounter airbag issues. Through inspections, I find sensor failures are the most common—dirt or internal component damage can cause detection failures. Wiring problems are also frequent, with loose connectors or short circuits leading to signal interruptions. Airbag module failures are more troublesome, potentially requiring software updates or replacements. Deployment depends on collision angle and speed; if the impact isn't strong enough by design, the airbag won't deploy. Poor maintenance, like aging batteries causing system crashes, can also affect performance. Don’t overlook common parts like blown fuses cutting off power. I advise car owners against DIY repairs and recommend professional diagnostic tools for safety checks. Regular maintenance can prevent issues and extend the system's lifespan for better safety.

As a safety-conscious car owner, I'm particularly worried about airbags not deploying. Possible reasons include sensor failure, where dirt or damage causes misjudgment. Wiring aging and short circuits are also common, with broken insulation preventing current flow. A faulty control module can completely shut down the system, and poor maintenance like a dead battery makes things worse. If the impact isn't strong enough, the airbag won't deploy. I regularly check my vehicle's systems and am careful not to disturb airbag wiring during part replacements. If any issues arise, I stop driving immediately and send the car for repairs—safety first, no risky driving. Keeping the car interior clean prevents sensor blockages.
