Stratus Sedan V6-2.7L VIN R (2002)
AIRBAG SQUIB STATUS
1. Using a DRBIII(R) read Airbag DTC's
If the active codes are present.
If neither of the codes is an active code.
SEAT BELT TENSIONER (SBT)
The JR41 4-door driver and front passenger seat belt (retractor) tensioners are mounted to the inboard side of the "B" pillar at the floor. The tensioner is
an integral part of the seat belt retractor. At the onset of an impact event the ACM uses the seat belt tensioner to rapidly retracts the seat belt. With the
slack removed, the occupant's forward motion in an impact will be reduced as will the likelihood of contacting interior components. The seat belt
tensioner cannot be repaired, if damaged or defective it must be replaced. The ACM continuously monitors the resistance of the seat belt tensioner
circuits an open or shorted conditions.
The JR27 convertible driver and front passenger seat belt (buckle) tensioners are mounted to the inboard side of the front seats. The seat belt buckle is
connected directly to the seat belt tensioner cable. At the onset of an impact event the ACM uses the seat belt tensioner to rapidly retract the seat belt
buckles. With the slack removed, the occupant's forward motion in an impact will be reduced as will the likelihood of contacting interior components.
The seat belt tensioner cannot be repaired, if damaged or defective it must be replaced. The ACM continuously monitors the resistance of the seat belt
tensioner circuits an open or shorted conditions.
SIDE IMPACT AIRBAG CONTROL MODULE (SIACM)
Supplemental driver and passenger curtain airbags provide side impact protection for the occupants. Each side airbag has it's own side impact airbag
control module (SIACM)to provide independent impact sensing and deployment. SIACM are located on the left and right B post just above the seat belt
retractor. One, same part number, SIACM is used on both side of the vehicle. However, for proper PCI bus operation each SIACM must have a unique
module identification. To provide the unique module identification for both, left and right, the SIACM software looks for a ground on cavity #5 of the
SIACM connector. If cavity #5 is grounded the SIACM communicates as a left SIACM otherwise it communicates as a right SIACM. The SIACM
performs 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, 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 (MIC)
requesting the airbag warning indicator 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.
WARNING: THE AIRBAG SYSTEM IS A SENSITIVE, COMPLEX ELECTROMECHANICAL UNIT. BEFORE ATTEMPTING TO
DIAGNOSE OR SERVICE ANY AIRBAG SYSTEM OR RELATED STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT
PANEL COMPONENTS YOU MUST FIRST DISCONNECT AND ISOLATE THE BATTERY NEGATIVE (GROUND) CABLE. WAIT
TWO MINUTES FOR THE SYSTEM CAPACITOR TO DISCHARGE BEFORE FURTHER SYSTEM SERVICE. THIS IS THE ONLY
SURE WAY TO DISABLE THE AIRBAG SYSTEM. FAILURE TO DO THIS COULD RESULT IN ACCIDENTAL AIRBAG
