The SRS consists of the following items:
•
Driver and passenger airbag modules (which include the inflators and
airbags)
•
safety belt pretensioners
•
Front passenger sensing system
•
“Passenger airbag off” or “pass airbag off” indicator lamp. Refer to
Front passenger sensing system
later in this chapter.
•
Driver and passenger side airbags
•
One or more impact and safing sensors
•
A readiness light and tone
•
A diagnostic module
•
The electrical wiring which connects the components
The diagnostic module monitors its own internal circuits as well as the
supplemental airbag electrical system wiring (including the impact
sensors), the system wiring, the airbag system readiness light, the airbag
back up power and the airbag ignitors.
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.
WARNING:
If the safety belt pretensioners deploy in an
accident, they will not function again (belt will not extract or
retract) and must be replaced immediately. Failure to replace the
retractor assemblies will increase the risk of injury.
