Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Description & Operation: Notes
The Supplemental Restraint System (SRS) is designed to provide increased accident protection for the driver by deploying air bag in a front-end collision. The air bag, stored in center of steering wheel, deploys in approximately 40 milliseconds after the impact sensors close. The air bag system is designed to be used with the 3-point safety belts.
During a front-end collision, the impact sensor(s) internal balls are thrown forward. The balls complete an electrical circuit and ignite the inflator to deploy air bag. At least 2 sensors, one safing and one front impact, must activate simultaneously to inflate air bag. SRS includes the following major components: diagnostic monitor, air bag module, air bag system readiness light (AIR BAG warning light), impact and safing sensors, ignitor assembly (in air bag module), clockspring, and associated wiring harnesses. See Fig 1 .
