III AIR BAGS



DRIVER AIR BAG (DAB)

The driver airbag module is located in the steering

wheel and its function is controlled by the SRS ECU.

A bag within the module inflates to protect the driver

in the event of a collision severe enough to deploy

the system.

The driver airbag module connects to the steering

column wiring harness via a rotary coupler called as

clock spring. Within the driver airbag module is a

squib which, when given the correct current by the

SRS ECU, inflates the airbag by initiating a chemical

reaction. In deployment, the airbag inflates within a

fraction of a second and then deflate at a controlled

rate as the driver body regions; typically head and

chest interact with airbag. Vents in the airbag control

its deflation.

The SRS ECU regularly applies a test current to the

driver airbag squib to confirm continuity of the igni-

tion circuitry.
