Airbags are one of the most critical safety features in modern vehicles. Designed to reduce the impact of a collision, they save countless lives every year. However, like any mechanical or electronic system, airbags can malfunction.
Regular maintenance and understanding what might cause problems with your airbag system are vital for ensuring it functions when you need it most. Below, we’re exploring a few things that could cause an airbag malfunction.
Damaged or Corroded Wires
The wiring that connects your car’s airbag system to other electronic components plays a crucial role in its proper deployment. Over time, these wires can become damaged due to wear and tear, accidents, or poor maintenance.
Corroded wires, often caused by exposure to moisture or salt in a humid climate, may interfere with the electrical signal required for the airbag to deploy. If your airbag warning light is illuminated on your dashboard, it might indicate wiring issues that need immediate attention.
Faulty Sensors
Faulty sensors are another common cause of airbag malfunctions. These sensors are responsible for detecting sudden deceleration or impact. If they fail or send inaccurate signals to the control unit, your airbags may not deploy at the right moment—or worse, they could deploy unexpectedly.
Sensor accuracy is affected by accidents, manufacturing defects, or even tampering. A quick diagnostic test from a professional can detect and resolve sensor issues before they become hazardous.
Issues With the Clock Spring
The clock spring is a coiled cable housed within the steering wheel, ensuring consistent electrical connections between the airbag and its control module. Over time, regular steering wheel movement can wear out the clock spring, leading to problems with airbag functionality.
If you notice a nonfunctional horn or buttons on your steering wheel, this could be a sign of clock spring failure that might also affect your airbag system. Addressing a worn-out clock spring promptly can prevent more extensive repairs.
The Role of 9-Cavity Connectors
Modern vehicles rely on intricate 9-cavity wiring systems and specialized connectors to ensure the secure and stable transmission of electrical signals. These connectors play a significant role in maintaining communication between sensors, the airbag control module, and the deployment mechanism.
If these connectors are improperly installed, damaged, or subject to wear and tear due to environmental elements, they can trigger airbag malfunctions. Ensuring that all connectors are intact during repairs is vital for your vehicle’s safety systems, including airbags.
Expired Airbags
While airbags themselves are highly durable, they do have a limited lifespan. Manufacturers recommend replacing airbags after a certain number of years, typically between 10 and 15.
Over time, the chemicals used in the deployment mechanism can degrade, or internal parts can wear out, making the airbag unreliable. Check your vehicle’s manual or consult with the manufacturer to determine how long your airbags should last and replace them if they’re overdue. And when it’s time to consider buying a new car, make this a key priority in your safety inspection.
Your airbag system is a lifeline in the event of a collision and keeping it in optimal condition is a responsibility you should not take lightly. Regular maintenance, inspections, and swift action when warning lights appear are essential steps to prevent malfunctions. For peace of mind and to make sure your airbag system is ready when you need it, schedule a professional inspection today with your trusted auto service provider.
