Description

Driver Airbag (DAB)

The Driver Airbag (DAB) is installed in the steering wheel and electrically connected to SRSCM via the clock spring. It protects the driver by deploying the airbag when frontal crash occurs. The SRSCM determines deployment of the Driver Airbag (DAB).

Clock Spring

This is a delivery equipment that delivers operation signal which generated from the sensors on front and side of vehicle to airbag module inplater (gas generating equipment) through inner cable.

Also it delivers operation signal of steering wheel remote control switch and horn to corresponded system through inner cable.

  

Never attempt to measure the circuit resistance of the airbag module (squib) even if you are using the specified tester. If the circuit resistance is measured with a tester, accidental airbag deployment will result in serious personal injury.
