3.1.2 CLOCKSPRING
The clockspring is mounted on the steering col-
umn behind the steering wheel. This assembly
consists of a plastic housing which contains a flat,
ribbon-like, electrically conductive tape that winds
and unwinds with the steering wheel rotation. The
clockspring is used to maintain a continuous elec-
trical circuit between the instrument panel wire
harness and the driver side airbag module,the horn
switch, and the vehicle speed control switches on
vehicles that are so equipped. The clockspring must
be properly centered when it is installed on the
steering column following any service removal, or it
will be damaged. The clockspring cannot be re-
paired it must be replaced.
3.1.3 PASSENGER AIRBAG (PAB)
The airbag door in the instrument paneltop cover
above the glove box is the most visible part of the
passenger side airbag system. Located under the
airbag door is the airbag cushion and its supporting
components. The airbag module includes a housing
to which the cushion and inflator are attached and
sealed. The airbag module cannot be repaired, and
must be replaced if deployed or in any way dam-
aged. The inflator assembly is mounted to the back
of the airbag module. The inflator includes a small
canister of highly compressed argon gas. The infla-
tor seals the hole in the airbag cushion so it can
discharge the compressed gas it contains directly
into the cushion when supplied with the proper
electrical signal. The airbag door has a living hinge
at the top, which is secured to the instrument panel
top cover. The door also has predetermined break-
out lines concealed beneath its decorative cover.
Upon airbag deployment, the airbag door will split
at the breakout lines and the door will pivot out of
the way.
WARNING: THE AIRBAG INFLATOR ASSEM-
BLY CONTAINS SODIUM AZIDE AND POTAS-
SIUM NITRATE. THESE MATERIALS ARE
POISONOUS AND EXTREMELY FLAMMABLE.
CONTACT WITH ACID, WATER, OR HEAVY
METALS MAY PRODUCE HARMFUL AND
IRRITATING GASES (SODIUM HYDROXIDE IS
FORMED IN THE PRESENCE OF MOISTURE)
OR COMBUSTIBLE COMPOUNDS. IN
ADDITION, THE PASSENGER AIRBAG
CONTAINS ARGON GAS PRESSURIZED TO
OVER 2500 PSI. DO NOT ATTEMPT TO
DISMANTLE AN AIRBAG MODULE OR
TAMPER WITH ITS INFLATOR. DO NOT
PUNCTURE, INCINERATE, OR BRING INTO
CONTACT WITH ELECTRICITY. DO NOT
STORE AT TEMPERATURE EXCEEDING 93°C
(200°F). FAILURE TO TAKE THE PROPER
PRECAUTIONSCOULDRESULTINACCIDENT-
AL AIRBAG DEPLOYMENT AND PERSONAL
INJURY OR DEATH.
WARNING: REPLACE AIRBAG SYSTEM
COMPONENTS ONLY WITH PARTS SPECI-
FIED IN THE CHRYSLER MOPAR PARTS
CATALOG. SUBSTITUTE PARTS MAY
APPEAR INTERCHANGEABLE, BUT INTERN-
AL DIFFERENCES MAY RESULT IN INFERIOR
OCCUPANT PROTECTION. THE FASTENERS,
SCREWS, AND BOLTS ORIGINALLY USED
FOR THE AIRBAG SYSTEM COMPONENTS
HAVE SPECIAL COATINGS AND ARE
SPECIFICALLY DESIGNED FOR THE AIRBAG
SYSTEM. THEY MUST NEVER BE REPLACED
WITH ANY SUBSTITUTES. ANY TIME A NEW
FASTENER IS NEEDED, REPLACE IT WITH
THE CORRECT FASTENERS PROVIDED IN
THE SERVICE PACKAGE OR SPECIFIED IN
THE MOPAR PARTS CATALOG. FAILURE TO
TAKE THE PROPER PRECAUTIONS COULD
RESULT IN ACCIDENTAL AIRBAG DEPLOY-
MENT AND PERSONAL INJURY OR DEATH.
3.1.4 SIDE IMPACT AIRBAG CONTROL
MODULES (SIACM)
They are located on the left and right B-post. The
SIACM perform self diagnostics and circuit tests to
determine if the system is functioning properly. If
the test finds a problem the SIACM will set both
active and stored diagnostic trouble codes. If a DTC
is active the SIACM will request that the airbag
warning lamp be turned on. The results of the
system test are transmitted on the PCI Bus to the
ACM once each second or on change in lamp state.
If the warning lamp status message from the either
SIACM contains a lamp on request theACM will set
an active DTC. At the same time as the DTC is set
the ACM sends a PCI Bus message to the mechan-
ical instrument cluster (MIC) requesting the airbag
warning lamp be turned on. Observe all ACM
warning and caution statements when servicing or
handling the SIACM. SIACM are not repairable
and must be replaced if they are dropped.
NOTE: When the Airbag Warning Indicator is
illuminated, interrogate the ACM.
3.1.5 SEAT AIRBAGS
The Left and Right seat airbag modules are
located in the outboard end of the front seat backs.
The airbag module contains a bag, an inflator (a
small canister of highly compressed argon gas) and
