The SRS consists of:
• driver and passenger air bag
modules (which include the
inflators and air bags).
• side air bags (if equipped). Refer
to Side air bag system later in this
chapter.
• one or more impact and safing
sensors.
• a readiness light and tone.
• and the electrical wiring which
connects the components.
The diagnostic module monitors its
own internal circuits and the
supplemental air bag electrical
system warning (including the
impact sensors), the system wiring,
the air bag system readiness light,
the air bag back up power and the
air bag ignitors.
Determining
if the system is
operational
The SRS uses a readiness light in
the instrument cluster or a tone to
indicate the condition of the
system. Refer to the Air bag
readiness section in the
Instrumentation chapter. Routine
maintenance of the air bag is not
required.
