Airbag warning lamp Crash sensing
Crash sensing and diagnostic modules
have been used in automobiles since air-
bags were first produced. The technical
information gained from these modules can
be useful to understanding the circum-
stances that led to the airbag deployment. In
addition, information from many field events
can be used in the aggregate to help manu-
facturers and others better understand real
world crashes. This, in turn, can lead to
improved automotive safety.
Your vehicle is equipped with two electronic
frontal sensors, which helps the sensing
system distinguish between a moderate
frontal impact and a more severe frontal
impact. Your vehicle is also equipped with a
crash sensing and diagnostic module,
which records information about the frontal
airbag system. The module records infor-
mation about the readiness of the system,
when the system commands airbag inflation
and driver’s safety belt usage at deployment
or in a near-deployment crash. The module
also records speed, engine rpm, brake and
throttle data etc.
Servicing the airbag system
The airbag system must be inspected as
part of the normal service program but oth-
erwise may be regarded as maintenance-
free.
WARNING
• If the airbag readiness light stays on
after you start your vehicle, it means
the airbag system may not be working
properly. See page 57.
• The airbags in your vehicle may not
inflate in a crash, or they could even
inflate without a crash.
• To help avoid injury to yourself or
others, have your vehicle serviced
right away if the airbag readiness light
stays on after you start your vehicle.
