Seat Airbag - Chrysler Concorde 2004 Service Manual

GENERAL INFORMATION
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 either SIACM contains a lamp on request the
ACM will set an active DTC. At the same time as the
DTC is set the ACM sends a PCI Bus message to the
mechanical instrument cluster (MIC) requesting
the airbag warning lamp be turned on. Observe all
ACM warning and caution statements when servic-
ing or handling the SIACM. SIACM are not repair-
able and must be replaced if they are dropped.

3.1.5 SEAT AIRBAG

The Left and Right seat airbags are located in the
outboard end of the front seat backs. The airbag
contains a bag, an inflator (a small canister of
highly compressed argon gas) and a mounting
bracket. The seat airbag cannot be repaired and
must be replaced if deployed or in any way dam-
aged. When supplied with the proper electrical
signal the inflator seals the hole in the airbag
cushion so it can discharge the compressed gas it
contains directly into the cushion. Upon deploy-
ment, the seat back trim cover will tear open and
allow the seat airbag to fully deploy between the
seat and the door.
Note: It will be necessary to remove the seat
back trim to gain access to the seat airbag
module connector when diagnosing the seat
airbag system.
THE SEAT AIRBAG MODULE CONTAINS
ARGON GAS PRESSURIZED TO OVER 2500
PSI. DO NOT ATTEMPT TO DISMANTLE AN
AIRBAG MODULE OR TAMPER WITH ITS
INFLATOR. DO NOT PUNCTURE, INCINER-
ATE, OR BRING INTO CONTACT WITH ELEC-
TRICITY. DO NOT STORE AT TEMPERA-
TURE EXCEEDING 93°C (200°F). REPLACE
AIRBAG SYSTEM
WITH PARTS SPECIFIED IN THE CHRYSLER
MOPAR PARTS CATALOG.
PARTS MAY APPEAR INTERCHANGEABLE,
BUT INTERNAL DIFFERENCES MAY RE-
SULT IN INFERIOR OCCUPANT PROTEC-
TION. THE FASTENERS, SCREWS, AND
BOLTS ORIGINALLY USED FOR THE AIR-
BAG SYSTEM COMPONENTS HAVE SPE-
CIAL COATINGS AND ARE SPECIFICALLY
DESIGNED FOR THE AIRBAG SYSTEM.
THEY MUST NEVER BE REPLACED WITH
ANY SUBSTITUTES. ANY TIME A NEW FAS-
TENER IS NEEDED, REPLACE IT WITH THE
CORRECT FASTENERS PROVIDED IN THE
SERVICE PACKAGE OR SPECIFIED IN THE
CHRYSLER MOPAR PARTS CATALOG.

3.1.6 SPECIAL TOOLS
Some airbag diagnostic test use special tools,
8310 and 8443 airbag load tool, for testing squib
circuits. The load tools contain fixed resistive loads,
jumpers and adapters. The fixed loads are con-
nected to cables and mounted in a storage case. The
cables can be directly connected to some airbag
system connectors. Jumpers are used to convert the
load tool cable connectors to the other airbag sys-
tem connectors. The adapters are connected to the
module harness connector to open shorting clips
and protect the connector terminal during testing.
When using the load tool follow all of the safety
procedures in the service information for discon-
necting airbag system components. Inspect the wir-
ing, connector and terminals for damage or mis-
alignment. Substitute the airbag load tool in place
of a Driver or Passenger Airbag, seat airbag, clock-
spring, or seat belt tensioner (use a jumper if
needed). Then follow all of the safety procedures in
the service information for connecting airbag sys-
tem components. Read the module active DTC's. If
the module reports NO ACTIVE DTC's the defective
component has been removed from the system and
should be replaced. If the DTC is still active, con-
tinue this process until all component in the circuit
have been tested. Then disconnect the module con-
nector and connect the matching adapter to the
module connector. With all airbags disconnected
and the adapter installed the squib wiring can be
tested for open or shorted conditions.
3.1.7 DIAGNOSTIC TROUBLE CODES
Airbag diagnostic trouble codes consist of active
and stored codes. If more than one code exists,
diagnostic priority should be given to the active
codes.
Each diagnostic trouble code is diagnosed by
following a specific testing procedure. The diagnos-
tic test procedures contain step-by-step instructions
for determining the cause of the trouble codes. It is
not necessary to perform all of the tests in this book
to diagnose an individual code.
Active diagnostic trouble codes for the airbag
system are not permanent and will change the
moment the reason for the code is corrected. In
certain test procedures within this manual, diag-
nostic trouble codes are used as a diagnostic tool.
3.1.7.1 ACTIVE CODES
The code becomes active as soon as the malfunc-
tion is detected or key-off, whichever occurs first.
An active trouble code indicates an on-going mal-
function. This means that the malfunction is cur-
rently there every time the airbag control module
checks that circuit/function. It is impossible to erase
