Purpose
The air bag system warning light notifies the driver of a malfunction in the SRS air bag system.
Function
If a malfunction occurs in the SRS air bag system, the air bag system warning light illuminates or flashes.

Construction
LEDs (light-emitting diode) have been adopted for the air bag system warning light.
The air bag system warning light is built into the instrument cluster.
Operation
When the ignition is switched ON, the instrument cluster illuminates the air bag system warning light for a specified period to indicate that the SRS air bag system is performing initialization diagnostics. If there is no malfunction in the SRS air bag system, the indicator light turns off.
If the SAS control module detects a malfunction in the SRS air bag system, it sends a warning signal to the instrument cluster via CAN communication. The instrument cluster illuminates or flashes the air bag system warning light based on the warning signal it receives to display the DTC.
If there is a malfunction in the SRS air bag system, the air bag system warning light displays DTCs according to the following patterns:

If there are several malfunctions in the SRS air bag system, the DTC of the highest priority ranking is displayed first.
