uppermost or away from the body in case being

carried vertically. Do not attempt to repair, open or

apply power (Multimeter) to the air bag module

terminals.

! CAUTION

B. PASSENGER AIRBAG (PAB)

The passenger airbag module is located below the

dashboard; above the glove box and its functioning

is controlled by the SRS ECU. A bag within the

module inflates to protect the passenger in the

event of a collision severe enough to deploy the

system.

Within the passenger 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 deflates at a

controlled rate as the passenger 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 passenger airbag squib to confirm continuity of

the ignition circuitry.
