Malfunction Lamp / Indicator: Description and Operation

Air Bag Lamp
The air bag lamp will illuminate continuously for approximately six seconds whenever the ignition switch is turned to the ON position if the air bag system is working properly. If an air bag system fault is present, the air bag lamp will either fail to illuminate, remain lit continuously or light in a flashing manner.

Tone Generator
The tone generator is internal to the diagnostic monitor. The air bag lamp is the prime indicator for determining the air bag system condition. However, a series of five sets of five tones will be heard if the air bag indicator lamp is inoperative and a fault occurs in the system. This indicates that the SRS requires service. Unless serviced, the SRS may not function properly in the event of a collision.
