Jeep-Wrangler-Air-Bags

Make your continued safety a top priority with Jeep Wrangler airbags at the ready. Your Wrangler SRS system includes a network of restraints, airbags, and sensors that work tirelessly to keep you and your passengers safe. These tools provide you with another level of safety as you and your SUV tackle new and exciting vistas.

What are some internal restraints common to most Wranglers?

Your Jeep model provides you with a network of protective airbags. These include:

  • Seat-Mounted Side Airbags
  • Passenger Advanced Front Airbags
  • Driver Advanced Front Airbags
  • Seat Belt Pre-tensioning Units
How do pyrotechnic seat belts work?

Your airbags are effective safety features but are only part of the overall safety system. Other venerable members of the Jeep safety crew are the many seat belts inside your vehicle, some of which may be pyrotechnic.

The idea behind pyrotechnic seat belt support systems is that drivers have better chances of avoiding injuries during crashes if they stay in their seats. Pyrotechnic seats work by using inertial sensors to keep track of the ongoing momentum of the SUV. If the system detects a severe deceleration of at least 5g, the inertial sensor initiates a process that cuts seat belt slack and restrains occupants. This action can prevent passengers from striking hard and potentially dangerous internal surfaces.

What are some airbag crash sensors you may need?

Like most automotive systems, the components of the airbag system need occasional replacement. Airbag sensors are responsible for deploying potentially life-saving systems and are thus key parts of the SRS safety system.

  • SRS Electronic Control Unit (ECU) - The brains behind the system, the ECU manages and sorts the many signals sent by the various SRS system sensors.
  • Deceleration Sensors - While designs vary from company to company, most SRS systems use a network of sensors capable of quickly reacting when a crash happens. D-type sensors form the front line of the sensor army, and designers usually install them on the front end of Jeep Wranglers and other SUVs. Another backup sensor, called a safing sensor, acts as a confirmation source for the D-sensor network. When both systems sense hard decelerations or impacts, they collaborate to fire the appropriate restraints.
What is a diagnostic module?

This is simply a part of the ECU that monitors other parts of the SRS network. As the master-monitor, the diagnostic module has the final say about whether a given airbag deploys. If the diagnostic module detects issues, it puts out a signal that shows up as an airbag-system warning light.
