System Readiness Indicator Lamp
The system readiness indicator is an instrument cluster-mounted lamp that will momentarily light whenever the ignition switch is turned from OFF to RUN if the air bag system is working properly. If the system is not functioning properly, the lamp will either fail to light, stay on continuously, or light in a flashing mode (if a system fault exists and the lamp is malfunctioning an audible tone will be heard indicating the need for service). If a fault occurs after the prove out the lamp will light either continuously or in a coded flashing mode.

Tone Generator
The air bag readiness lamp is the prime means of determining the air bag system condition. However, a series of five sets of five tones will be heard if the readiness lamp is out and a fault occurs in the system. This also means that the Supplemental Driver Air Bag System is in need of service. The tone pattern will repeat periodically until the fault and lamp outage are serviced. Unless serviced, the Supplemental Driver Air Bag Restraint System may not function properly in the event of an accident.
