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.
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 toAirbag readinesssection
in theInstrument Clusterchapter. 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.
S.O.S. Post Crash Alert
The S.O.S Post Crash Alert automatically flashes the turn signal lamps
and sounds the horn three times at four second intervals in the event of
a serious impact that deploys an airbag (front, side, side curtain or
Safety Canopy) or the safety belt pretensioners.
The S.O.S. Post Crash Alert can be turned off when any one of the
following actions are taken by the driver or any other person:
•pressing the hazard control button,
•or pressing the panic button on the remote entry transmitter.
The feature will continue to operate until the vehicle runs out of power.
Disposal of airbags and airbag equipped vehicles
See authorized dealer. Airbags MUST BE disposed of by qualified
personnel.
