Clockspring - Chrysler Concorde 2004 Service Manual

Located under the trim cover are the horn switch,
the airbag cushion, and the airbag cushion support-
ing components. The airbag includes a housing to
which the cushion and inflator are attached and
sealed. The airbag cannot be repaired, and must be
replaced if deployed or in any way damaged. The
inflator assembly is mounted to the back of the
airbag module. The inflator seals the hole in the
airbag cushion so it can discharge the gas it pro-
duces directly into the cushion when supplied with
the proper electrical signal. The protective trim
cover is fitted to the front of the airbag module and
forms a decorative cover in the center of the steer-
ing wheel. Upon airbag deployment, this cover will
split at a predetermined breakout line.
THE AIRBAG MODULE INFLATOR ASSEM-
BLY CONTAINS SODIUM AZIDE AND POTAS-
SIUM NITRATE. THESE MATERIALS ARE
POISONOUS AND EXTREMELY FLAMMA-
BLE. CONTACT WITH ACID, WATER, OR
HEAVY METALS MAY PRODUCE HARMFUL
AND IRRITATING GASES (SODIUM HY-
DROXIDE IS FORMED IN THE PRESENCE
OF MOISTURE) OR COMBUSTIBLE COM-
POUNDS. DO NOT PUNCTURE, INCINER-
ATE, OR BRING INTO CONTACT WITH ELEC-
TRICITY. DO
TEMPERATURE EXCEEDING 93°C (200° F).

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 panel top 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 it's supporting
components. The airbag includes a housing to
which the cushion and inflator are attached and
sealed. The airbag cannot be repaired, and must be
replaced if deployed or in any way damaged. The
inflator assembly is mounted to the back of the
airbag module. The inflator includes a small canis-
ter of highly compressed argon gas. The inflator

GENERAL INFORMATION
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.

3.1.4 SIDE IMPACT AIRBAG CONTROL
MODULES (SIACM)
The 2003 LH uses two identical side impact
airbag control modules (SIACM) that share the
same part number. They are located on the left and
right B-post with the connector pointed forward.
For proper PCI bus operation each SIACM must
have a unique module identification. To provide the
unique module identification the SIACM software
looks for a ground on cavity # 5. If cavity # 5 is
grounded the SIACM communicates as a left
SIACM otherwise it communicates as a right
SIACM. The SIACM perform self diagnostics and
circuit tests to determine if the system is function-
ing properly. If the test find a problem the SIACM
will set both active and stored diagnostic trouble
codes. If a DTC is active the SIACM will request
