11.1.6.2.3. AIR BAGS

A. 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

ignition circuitry.
