WARNING: Several air bag system components get hot after
inflation. Do not touch them after inflation.
WARNING: If the air bag has deployed, the air bag will not
function again and must be replaced immediately. If the air
bag is not replaced, the unrepaired area will increase the risk of injury
in a collision.
The SRS consists of:
• driver and passenger airbag modules (which include the inflators and
airbags)
• seat-mounted side airbags. Refer to Seat-mounted side airbag system
later in this chapter
• safety belt pretensioners
• one or more impact and safing sensors
• a readiness light and tone
• and the electrical wiring which connects the components
• Side curtain airbag system. Refer to Safety Canopy System later in
this chapter.
• Front passenger sensing system. Refer to Front passenger sensing
system later in this chapter.
• “Passenger airbag off” or “pass airbag off” indicator lamp. Refer to
Front passenger sensing system later in this chapter.
The diagnostic module monitors its own internal circuits and the
supplemental airbag electrical system wiring (including the impact
sensors), the system wiring, the airbag system readiness light, the airbag
backup power, the airbag ignitors and safety belt pretensioners.
Front passenger sensing system
The front passenger sensing system is designed to meet the regulatory
requirements of Federal Motor Vehicle Safety Standard (FMVSS) 208
and is designed to disable (will not inflate) the front passenger’s frontal
airbag under certain conditions.
The front passenger sensing system works with sensors that are part of
the front passenger’s seat and safety belt. The sensors are designed to
detect the presence of a properly seated occupant and determine if the
front passenger’s frontal airbag should be enabled (may inflate) or
disabled (will not inflate).
