Electrical System

The air bag system is powered directly from the battery. The system can function with the ignition switch in any position, including OFF and LOCK. The system can also function when the driver or passenger seats are unoccupied. The electrical system performs three main functions:
- Detects an impact
- Switches electric power to the igniter
- Monitors the system to determine readiness

The electrical system components include:
- Electronic diagnostic monitor with integrated backup power supply
- Air bag system readiness indicator
- Wiring harness and contact clockspring assembly
- Sensors
- The igniter within the driver and passenger air bags
