Malfunction Lamp / Indicator: Description and Operation

System Readiness Indicator
The system readiness indicator will light continuously for approximately six seconds whenever the ignition switch is turned from OFF to RUN if the air bag is working properly, the indicator will either fail to light, remain lit continuously, or light in a flashing manner. The flashing manner may not occur until approximately 30 seconds after the ignition switch has been turned from OFF to RUN. This is the time required for the diagnostic monitor to test and verify any and all system faults. If the air bag indicator is inoperative and an air bag system fault exists, a tone will sound signaling that the air bag readiness indicator is inoperative and an air bag system fault exists.


Tone Generator
The air bag readiness indicator 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 indicator is out and a fault occurs in the system. This also means that the Supplemental Air Bag System is in need of service. Unless serviced, the Supplemental Air Bag Restraint System may not function properly in the event of an accident.
