The SRS consists of the following items:
• Driver and passenger air bag modules (which include the inflators and
air bags)
• Driver and passenger side air bags
• 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 air bag electrical system wiring (including the impact
sensors), the system wiring, the air bag system readiness light, the air
bag back up power and the air bag ignitors.
Several air bag system components get hot after inflation. Do not
touch them after inflation.
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.
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.
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 Air bag readiness section
in the Instrument cluster chapter. Routine maintenance of the air bag is
not required.
A difficulty with the system is indicated by one or more of the following:
• The readiness light will either
flash or stay lit.
• The readiness light will not
illuminate immediately after
ignition is turned on.
