Electrical System

The Supplemental Air Bag Restraint System (SRS) is powered directly from the battery. The SRS can function with the ignition switch in any position, including OFF and LOCK. The SRS can also function when the driver or passenger seats are unoccupied. The electrical system performs three main functions:
- Monitors the system to determine system readiness
- Detects impacts
- Supplies electrical current to the igniter

The electrical system components include:
- Air bag diagnostic monitor with internal backup power supply
- Air bag indicator
- Wiring harness and air bag sliding contact assembly
- Sensors (crash and safing)
- Igniter within the driver and passenger air bags
