FORD 2009 E-450 v.1 - Manual (Page 111)

The SRS consists of:
• driver and passenger airbag modules (which include the inflators and
airbags)
• one or more impact and safing sensors
• safety belt pretensioners
• a readiness light and tone
• a diagnostic module
• and the electrical wiring which connects the components
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
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.
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 Airbag readiness section
in the Instrument Cluster chapter. Routine maintenance of the airbag 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.
• A series of five beeps will be heard. The tone pattern will repeat
periodically until the problem and/or light are repaired.
If any of these things happen, even intermittently, contact your
authorized dealer as soon as possible. Unless serviced, the system may
not function properly in the event of a collision.
