Construction

GENERAL




- The SRS airbag consists of an airbag control module, left and right front sub sensors, electric sensor and safety sensor built into the control module, airbag modules of driver and passenger containing an inflator and airbag, and side airbag sensor and side airbag module containing an inflator and airbag (Side airbag equipped model).

- FRONT AIRBAG SYSTEM:
A frontal impact causes the safety sensor, electric sensor and front sub sensor to input an impact signal to the CPU. The CPU judges whether the airbags should be inflated or not based on these input signal values.

- SIDE AIRBAG SYSTEM:
Input of a side impact signal that exceeds a preset value causes the airbag on the side that received the impact to inflate.

AIRBAG MODULE




1. FRONT AIRBAG
The driver's airbag module is located at the center of the steering wheel, and passenger's airbag module is located at upper side of instrument panel, and it each contains an airbag and inflator. If a frontal collision occurs, the inflator produces a large volume of gas inflating the airbag in a very short time.




2. SIDE AIRBAG
The side airbag module is located at the outside of the front backrest, and it contains an airbag and an inflator.

If a side collision occurs, the inflator produces a large volume of gas inflating the airbag in a very short time.

AIRBAG CONNECTOR

1. DESCRIPTION
The SRS airbag adopts a connector which has a double lock mechanism and coupling error detection mechanism for enhanced reliability. If coupling is incomplete, the airbag warning light comes on in the combination meter.




2. DISCONNECTION (HARNESS TO HARNESS)




3. DISCONNECTION (FRONT SUB SENSOR AND SIDE AIRBAG MODULE)




AIRBAG WARNING LIGHT
The airbag warning light is located inside the combination meter. It illuminates if a poor connection occurs, or if the airbag control module detects an abnormality. When the airbag system is normal, this light goes out about 7 seconds after turning the ignition switch ON.
