SEAT BELT TENSIONER
DESCRIPTION
The seat belt system incorporates Seat Belt Ten-
sioners. The tensioner is designed to hold the occu-
pant in their respective seat by retracting the seat
belt up to four inches. They are integral to the front
seat belt buckles and cannot be serviced. If found

defective they must be replaced. After an airbag
deployment, the tensioner must be replaced.
OPERATION
At the onset of an impact event, each tensioner
uses a pyrotechnic device which is triggered simulta-
neously with the airbags to rapidly retract the seat
belts. With the slack removed, the occupant's forward
motion in an impact will be reduced as will the like-
lihood of contacting interior components. After an
impact that deploys the airbags, the seat belt ten-
sioner assembly must be replaced.
The Occupant Restraint Controller (ORC) monitors
the seat belt tensioner circuit resistance and reports
active and stored Diagnostic Trouble Codes (DTC's) if
any problem is found.
Once a vehicle has been in an accident, the tensioner
must be replaced along with any deployed airbags and
broken or damaged parts. Refer to the proper Body
Diagnostic Procedures manual for diagnosis and testing.
WARNING: WHEN THE FRONT AIRBAG IS
DEPLOYED, THE TENSIONER WILL HAVE
DEPLOYED ALSO AND SHOULD BE REPLACED.

SIDE IMPACT AIRBAG
CONTROL MODULE
DESCRIPTION
The side airbag system is a safety devise designed
to reduce the risk of fatality or serious injury, caused
by a side impact of the vehicle.
Vehicles equipped with side impact airbags use two
Side Impact Airbag Control Modules (SIACM). One is

located on each respective side body B-pillar. Each
contains an impact sensor that senses a side impact
occurrence. The SIACM communicates with the ORC
via the PCI bus in order to notify the driver of any
potential side airbag system problem.
OPERATION
The impact sensor provides verification of the
direction and severity of the side impact. The right
side SIACM controls the right seat airbag. The left
side SIACM controls the left seat airbag. In the event
of a side impact the appropriate SIACM will send an
electronic signal to its airbag, deploying the airbag.
The SIACM communicates with the Occupant
Restraint Controller (ORC) via the PCI bus circuit.
The accelerometer pulses are sent to a micropro-
cessor, which contains a decision algorithm. When an
impact is severe enough to require airbag protection,
the SIACM microprocessor sends a signal to deploy
the side airbag that completes the electrical circuits
to the right or left side airbag. The sensor is cali-
brated for the specific vehicle and reacts to the sever-
ity and direction of the impact.
REMOVAL
(1) Disconnect and isolate the battery negative
cable terminal.(2) Remove the lower B-pillar trim from the appro-
priate side of the vehicle. Refer to Body, Interior,
B-Pillar Lower Trim, Removal.
(3) Remove the three SIACM retaining screws and
remove the module from the vehicle.
(4) Disconnect the SIACM electrical connector.
INSTALLATION

SPEED CONTROL
DESCRIPTION
The speed control system is electronically con-
trolled and vacuum operated. The electronic control
is integrated into the powertrain control module,
located on the driver's side under the speed control
servo. The controls are located on the steering wheel.
The ON, OFF, and SET buttons are located on the
left side of the airbag module. The RESUME,
ACCEL, CANCEL and COAST buttons are located on
the right side of the airbag module (Fig. 1).The system is designed to operate at speeds above
30 mph (48 km/h).
WARNING: THE USE OF SPEED CONTROL IS NOT
RECOMMENDED WHEN DRIVING CONDITIONS DO
NOT PERMIT MAINTAINING A CONSTANT SPEED,
SUCH AS IN HEAVY TRAFFIC OR ON ROADS THAT
ARE WINDING, ICY, SNOW COVERED, OR SLIP-
PERY.
OPERATION
When speed control is activated by depressing the
ON switch, the PCM allows a set speed to be stored
in RAM for speed control. To store a set speed,
depress the SET switch while the vehicle is moving
at a speed between 30 and 85 mph. In order for the
speed control to engage, the brakes cannot be
applied, nor can the gear selector be indicating the
transmission is in Park or Neutral. The speed control
can be disengaged manually by:
²Stepping on the brake pedal
²Depressing the OFF switch
²Depressing the CANCEL switch.
²Depressing the clutch pedal
NOTE: Turning the system off by depressing the
OFF switch or turning off the ignition switch will
erase the set speed stored in the PCM.
For added safety, the speed control system is pro-
grammed to disengage for any of the following condi-
tions:
²An indication of Park or Neutral
Fig. 1 SPEED CONTROL SWITCHES - Typical
RSSPEED CONTROL8P-1
ProCarManuals.com

²A rapid increase rpm (indicates that the clutch
has been disengaged)
²Excessive engine rpm (indicates that the trans-
mission may be in a low gear)
²The speed signal increases at a rate of 10 mph
per second (indicates that the co-efficient of friction
between the road surface and tires is extremely low)
²The speed signal decreases at a rate of 10 mph
per second (indicates that the vehicle may have
decelerated at an extremely high rate)
²If the actual speed is not within 20 mph of the
set speed. The previous disengagement conditions are
programmed for added safety.
Once the speed control has been disengaged,
depressing the RESUME switch when speed is
greater than 25 mph allows the vehicle to resume
control to the target speed that was stored in the
PCM.
While the speed control is engaged, the driver can
increase the vehicle speed by depressing the ACCEL
switch. The new target speed is stored in the PCM
when the ACCEL switch is released. The PCM also
has a9tap-up9feature in which target speed
increases by 2 mph for each momentary switch acti-
vation of the ACCEL switch. The PCM also provides
a means to decelerate to a new lower target speed
without disengaging speed control. Depress and hold
the COAST switch until the desired speed is reached,
then release the switch.
The PCM also has a ªTap Downº feature in which
target speed decreases at 1 mph for each momentary
switch activation of the coast switch.
OPERATION - INTERACTIVE SPEED CONTROL
(4 Speed EATX Only)
Interactive means that communication between the
PCM and the TCM is taking place. Interactive speed
control avoids unnecessary shifting for smoother, qui-
eter operation and when downshifts are required,
makes the shifts smoother.
CLIMBING A GRADE
DESCRIPTION
When climbing a grade the interactive speed con-
trol tries to maintain the set speed by increasing the
throttle opening, while inability/delaying downshifts.
OPERATION
If opening the throttle alone cannot maintain the
set speed and the vehicle speed drops more than three
mph below the set speed, the transmission will down-
shift to third gear. If the vehicle continues to lose
speed, by more than 6 mph, the transmission will
downshift again to maintain the set speed. After the
vehicle encounters a less-steep grade, or has crestedthe grade (reduced the load on the powertrain) and
can maintain the set speed at a reduced throttle posi-
tion, the transmission will upshift, as appropriate,
until the set speed can be maintained in Overdrive.
GRADE HUNTING
DESCRIPTION
All vehicles equipped with a four speed automatic
transmission have a grade hunting feature for the 2nd
to 3rd gear upshift and the 3rd to Overdrive upshift.
OPERATION
The TCM identifies the powertrain loading condi-
tions and selects the proper gear to maintain the cur-
rent vehicle speed. Under moderate loading
conditions the transaxle will stay in 3rd gear until
the top of the grade is reached or the powertrain
loading is reduced.
If powertrain loading is severe, the transaxle may
shift into 2nd gear and remain there until power-
train loading is reduced, then a 2nd to 3rd gear
upshift will be scheduled. Grade hunting features
always operate regardless of whether or not the
interactive speed control is engaged.If the interac-
tive speed control is not engaged and power-
train loading is not reduced, the driver may
have to completely lift off of the throttle before
an upshift will occur. If the driver does lift off the
throttle to induce an upshift under these conditions,
vehicle speed will reduce and the Overdrive to 3rd
and 3rd to 2nd gear downshifts will reoccur when the
throttle is reapplied. If grade hunting is repeatedly
induced by the driver, transaxle damage may result.
AUTOMATIC SPEED CONTROL OVERSPEED
REDUCTION
DESCRIPTION
Transmission control software includes an auto-
matic speed control overspeed reduction feature. This
maintains vehicle speed at the selected set point
when descending a grade.
OPERATION
The Transmission Control Module (TCM) first
senses that the speed control is set. If the set speed
is exceeded by more than 4 mph (6.5 km/hr) and the
throttle is closed, the TCM causes the transaxle to
downshift to THIRD gear. After downshifting, the
automatic speed control resumes normal operation.
To ensure that an upshift is appropriate after the set
speed is reached, the TCM waits until the speed con-
trol system opens the throttle at least 6 degrees
before upshifting to OVERDRIVE again.
8P - 2 SPEED CONTROLRS
SPEED CONTROL (Continued)
ProCarManuals.com

If the driver applies the brakes, canceling auto-
matic speed control operation with the transaxle still
in THIRD gear, the TCM maintains this gear until
the driver opens the throttle at least 6 degrees to
avoid an inappropriate upshift. The upshift is also
delayed for 2.5 seconds after reaching the 6 degrees
throttle opening in anticipation that the driver might
open the throttle enough to require THIRD gear.
This will avoid unnecessary and disturbing transmis-
sion cycling. If the automatic speed control RESUME
feature is used after braking, the upshift is delayed
until the set speed is achieved to reduce cycling and
provide better response.
DIAGNOSIS AND TESTING - ROAD TEST
Perform a vehicle road test to verify reports of
speed control system malfunction. The road test
should include attention to the speedometer. Speed-
ometer operation should be smooth and without flut-
ter at all speeds.
Flutter in the speedometer indicates a problem
which might cause surging in the speed control sys-
tem. The cause of any speedometer problems should
be corrected before proceeding. Refer to the Instru-
ment Panel and Gauges for speedometer diagnosis.
If a road test verifies an inoperative system, and
the speedometer operates properly, check for:²A Diagnostic Trouble Code (DTC). If a DTC
exists, conduct tests per the Powertrain Diagnostic
Procedures service manual.
²A misadjusted brake (stop) lamp switch. This
could also cause an intermittent problem.
²Loose or corroded electrical connections at the
servo. Corrosion should be removed from electrical
terminals and a light coating of Mopar Multipurpose
Grease, or equivalent, applied.
²Leaking vacuum reservoir.
²Loose or leaking vacuum hoses or connections.
²Defective one-way vacuum check valve.
²Secure attachment at both ends of the speed
control servo cable.
²Smooth operation of throttle linkage and throttle
body air valve.
²Conduct electrical test at PCM.
²Failed speed control servo. Do the servo vacuum
test.
CAUTION: When test probing for voltage or conti-
nuity at electrical connectors, care must be taken
not to damage connector, terminals or seals. If
these components are damaged, intermittent or
complete system failure may occur.

SERVO
DESCRIPTION
The servo unit consists of a solenoid valve body,
and a vacuum chamber. The solenoid valve body con-
tains three solenoids:
²Vacuum
²Vent
²Dump
The vacuum chamber contains a diaphragm with a
cable attached to control the throttle linkage.
OPERATION
The PCM controls the solenoid valve body. The
solenoid valve body controls the application and
release of vacuum to the diaphragm of the vacuum
servo. The servo unit cannot be repaired and is ser-
viced only as a complete assembly.
Power is supplied to the servo by the PCM through
the brake switch. The PCM controls the ground path
for the vacuum and vent solenoids.
The dump solenoid is energized anytime it receives
power. If power to the dump solenoid is interrupted,
the solenoid dumps vacuum in the servo. This pro-
vides a safety backup to the vent and vacuum sole-
noids.
The vacuum and vent solenoids must be grounded
at the PCM to operate. When the PCM grounds the
vacuum servo solenoid, the solenoid allows vacuum
to enter the servo and pull open the throttle plate
using the cable. When the PCM breaks the ground,
the solenoid closes and no more vacuum is allowed to
enter the servo. The PCM also operates the vent sole-
noid via ground. The vent solenoid opens and closes a
passage to bleed or hold vacuum in the servo as
required.The PCM duty cycles the vacuum and vent sole-
noids to maintain the set speed, or to accelerate and
decelerate the vehicle. To increase throttle opening,
the PCM grounds the vacuum and vent solenoids. To
decrease throttle opening, the PCM removes the
grounds from the vacuum and vent solenoids.

SWITCH
DESCRIPTION
There are two separate switch pods that operate
the speed control system and are located on the
steering wheel.
OPERATION
The speed control system has five separate resis-
tive switches that provide a single multiplexed
(MUX) voltage inputs to the PCM.The switch names
are: ON, OFF, SET, COAST, RESUME, ACCEL, TAP-
UP, COAST, and CANCEL. Based on conditions when
the buttons are pushed (and released), the five volt-
ages ranges provided to the PCM result in the follow-
ing functions: ON, OFF, SET, COAST, RESUME,
ACCEL, TAP-UP, COAST, and CANCEL. Refer to the
Speed Control Section for more information
Also the PCM receives an input from the brake
switch to sense whether the brake pedal has been
depressed. When the PCM receives the brake
depressed input, it turns off power to the speed con-
trol servo and disengages speed control.
The individual switches cannot be repaired. If one
switch fails, the entire switch module must be
replaced.
REMOVAL
The speed control switches are mounted in the
steering wheel and wired through the clock spring
device under the airbag module.
