Air Bag Warning Lamp: Description and Operation
Airbag Warning Lamp
Ignition voltage is applied to the "AIR BAG" warning lamp when the ignition switch is at the ON or START positions. The SDM controls the lamp by
providing ground with a lamp driver. The "AIR BAG" warning lamp is used in the SRS to do the following:
1. Verify lamp and SDM operation by flashing SEVEN (7) times when the ignition switch is first turned "ON".
2. Warn the vehicle driver of SRS electrical system malfunctions which could potentially affect the operation of the SRS. These malfunctions could
result in nondeployment in case of a frontal crash or deployment for conditions less severe than intended.
The "AIR BAG" warning lamp is the key to driver notification of SRS malfunctions. For proper lamp operation, refer to the "SRS Diagnostic System
Check". See: Testing and Inspection/Component Tests and General Diagnostics/SRS Diagnostic System Check
