How The Front Airbag System Works
•
The front airbag control module determines if a frontal
impact is severe enough to require the front airbags to
inflate. Based on the level of collision severity, the front
airbag control module determines the proper rate of
inflation. The front airbag inflators are designed to
provide different rates of airbag inflation. The front
airbag control module will not detect roll over, or rear
collisions.
The front airbag control module also monitors the
readiness of the electronic parts of the system when-
ever the ignition switch is in the START or ON
positions. These include all of the items listed above
except the knee bolster, instrument panel and the
steering wheel and column. If the key is in the OFF
position, in the ACC position, or not in the ignition
switch, the front airbags are not on and will not inflate.
The front airbag control module sends a
message to the instrument cluster to turn on
the AIRBAG light in the instrument panel
for 6 to 8 seconds when the ignition switch is
first turned ON, then turns the light off. If the front
control module detects a malfunction in any part of the
system, the airbag light will turn on either momen-
tarily or continuously.
WARNING!
Ignoring the AIRBAG light in your instrument panel
could mean you won’t have the airbags to protect
you in a collision. If the light does not come on, stays
on after you start the vehicle, or if it comes on as you
drive, have the airbag system checked right away.
