Description & Operation: Description

The Driver Airbag (DAB) module is installed on the steering wheel and is electrically connected to the SRS Control Module (SRSCM) via the clock spring. In the event of a front collision, the airbag is deployed to protect the driver.
The clock spring is a device that transmits the operation signal generated from the sensors installed on the front and side of the vehicle to the inflator (gas generator) of the airbag module via the internal cable. It also transmits the steering wheel remote control switch and horn operation signals to the system via the internal cable.

WARNING: Direct resistance measurement of the airbag module is very dangerous as it can cause the airbag deployment.

NOTE: If the airbag is deployed due to an accident, the clock spring cannot be repaired or reused because there is a possibility of damage to the clock spring due to heat and impact caused by the explosion of the airbag module inflator (gas generating device). Be sure to replace with a new one.
