Driver Side Air Bag Module

The driver side air bag module is serviced as a complete assembly. Perform proper disposal procedure as necessary. The driver side air bag module is mounted in the center of the steering wheel. The driver side air bag module consists of the following components:
- Inflator.
- Airbag.
- Mounting plate and retainer ring.
- Steering wheel trim cover.

Inflator
- When the sensors close, signaling a crash, electrical energy flows to the air bag inflator.
- Inside the inflator, an igniter converts the electrical signal to thermal energy (heat), causing the ignition of the inflator gas generant.
- This ignition reaction combusts the sodium azide/potassium nitrate gas generant in the inflator, producing nitrogen gas, which inflates the air bag.
- The inflator is not serviceable.
