DESCRIPTION
The SRS warning light is located on the combination meter assembly.
When the SRS is normal, the SRS warning light comes on for approximately 6 seconds after the ignition switch is turned from the LOCK position to ON position, and then goes off automatically.
If there is a malfunction in the SRS, the SRS warning light comes on to inform the driver of a problem.
When terminals TC and CG of the DLC3 are connected, the DTC is displayed by blinking of the SRS warning light.
The SRS is equipped with a voltage-increase circuit (DC-DC converter) in the center airbag sensor assembly in case the source voltage drops.
When the battery voltage drops, the voltage-increase circuit (DC-DC converter) functions to increase the voltage of the SRS to normal voltage.
A malfunction in this circuit is not recorded in the center airbag sensor assembly. The SRS warning light automatically goes off when the source voltage returns to normal.
The signal to illuminate the SRS warning light is transmitted from the center airbag sensor assembly to the combination meter assembly through the multiplex communication system.

INSPECTION PROCEDURE
1 CHECK MULTIPLEX COMMUNICATION SYS
HINT: The center airbag sensor assembly of this system is connected to the multiplex communication system.
Therefore, before starting troubleshooting, make sure to check that there is no trouble in the multiplex communication system.
OK: The Multiplex communication system DTC is not output
2 CHECK BATTERY
Standard voltage: 11 to 14 V
3 CHECK CONNECTORS
OK: The connectors are properly connected.
4 CHECK WIRE HARNESS (SOURCE VOLTAGE OF CENTER AIRBAG SENSOR ASSEMBLY)
Standard voltage
Standard resistance
5 CHECK WIRE HARNESS (SOURCE VOLTAGE OF COMBINATION METER ASSEMBLY)
Standard voltage
Standard resistance
6 CHECK SRS WARNING LIGHT
OK: After the primary check period, SRS warning light goes off for approximately 10 seconds, and remains on.
HINT: The primary check period shows approximately 6 seconds after the ignition switch is turned to the ON position.
