SUPPLEMENTARY RESTRAINT SYSTEM (SRS)

1.7.2.3. 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.
