SPECIAL TOOLS - AIRBAG SYSTEM
AIRBAG CONTROL MODULE
DESCRIPTION
The Airbag Control Module (ACM) is concealed
underneath the plastic ACM trim cover (automatic
transmission) or center console (manual transmis-
sion), directly below the instrument panel in the pas-
senger compartment of the vehicle. The ACM is
secured with screws to a stamped steel mounting
bracket located under the instrument panel center
support bracket on the floor panel transmission tun-
nel. The ACM contains an electronic microprocessor,
an electronic impact sensor, an electromechanical saf-
ing sensor, and an energy storage capacitor. TheACM is connected to the vehicle electrical system
through a take out and connector of the instrument
panel wire harness.
The ACM cannot be repaired or adjusted and, if
damaged or faulty, it must be replaced.
OPERATION
The microprocessor in the ACM contains the airbag
system logic circuits, and it monitors and controls all
of the airbag system components. The ACM also uses
On-Board Diagnostics (OBD) and can communicate
with other electronic modules in the vehicle as well
as with the DRBIIItscan tool using the Chrysler
Collision Detection (CCD) data bus network. This
method of communication is used for control of the
airbag indicator in the ElectroMechanical Instrument
Cluster (EMIC) and for airbag system diagnosis and
testing through the 16-way data link connector
located on the lower left edge of the instrument
panel. (Refer to 8 - ELECTRICAL/ELECTRONIC
CONTROL MODULES/COMMUNICATION - OPER-
ATION). The ACM microprocessor continuously mon-
itors all of the airbag system electrical circuits to
determine the system readiness. If the ACM detects
a monitored system fault, it sets an active Diagnostic
Trouble Code (DTC) and sends messages to the
EMIC over the CCD data bus to turn on the airbag
indicator. (Refer to 8 - ELECTRICAL/INSTRUMENT
CLUSTER/AIRBAG INDICATOR - OPERATION). If
the airbag system fault is still present when the igni-
tion switch is turned to the Off position, the DTC is
stored in memory by the ACM. However, if a fault
does not recur for a number of ignition cycles, the
ACM will automatically erase the stored DTC.
The ACM receives battery current through two cir-
cuits, on a fused ignition switch output (run) circuit
through a fuse in the Junction Block (JB), and on a
fused ignition switch output (start-run) circuit
through a second fuse in the JB. The ACM is
grounded through a ground circuit and take out of
the instrument panel wire harness. This take out has
a single eyelet terminal connector secured by a nut to
a ground stud located on the forward extension of the
left front fender wheel housing in the engine com-
partment. Therefore, the ACM is operational when-
ever the ignition switch is in the Start or On
positions. The ACM also contains an energy-storage
capacitor. When the ignition switch is in the Start or
On positions, this capacitor is continually being
charged with enough electrical energy to deploy the
airbags for up to one second following a battery dis-
connect or failure. The purpose of the capacitor is to
provide backup airbag system protection in case
there is a loss of battery current supply to the ACM
during an impact. The capacitor is only serviced as a
unit with the ACM.

RESTRAINTS (Continued)

Two sensors are contained within the ACM, an
electronic impact sensor and a safing sensor. The
electronic impact sensor is an accelerometer that
senses the rate of vehicle deceleration, which pro-
vides verification of the direction and severity of an
impact. A pre-programmed decision algorithm in the
ACM microprocessor determines when the decelera-
tion rate as signaled by the impact sensor indicates
an impact that is severe enough to require airbag
system protection. When the programmed conditions
are met, the ACM sends an electrical signal to deploy
the airbags. The safing sensor is an electromechani-
cal sensor within the ACM that is connected in series
between the ACM microprocessor airbag deployment
circuit and the airbags. The safing sensor is a nor-
mally open switch that is used to verify or confirm
the need for an airbag deployment by detecting
impact energy of a lesser magnitude than that of the
electronic impact sensor, and must be closed in order
for the airbags to deploy. The impact sensor and saf-
ing sensor are calibrated for the specific vehicle, and
are only serviced as a unit with the ACM.

OPERATION - SPEED CONTROL SYSTEM
Gas Engines and/or Diesel With Automatic Trans.
When speed control is selected by depressing the
ON switch, the PCM allows a set speed to be stored
in PCM RAM for speed control. To store a set speed,
depress the SET switch while the vehicle is moving
at a speed between 35 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 (if equipped).
NOTE: 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.
²A rapid increase of rpm (indication 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 coefficient 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).
Once the speed control has been disengaged,
depressing the RES/ACCEL switch (when speed is
greater than 30 mph) restores the vehicle to the tar-
get speed that was stored in the PCM.
While the speed control is engaged, the driver can
increase the vehicle speed by depressing the RES/AC-
CEL switch. The new target speed is stored in the
PCM when the RES/ACCEL is released. The PCM
also has a9tap-up9feature in which vehicle speed
increases at a rate of approximately 2 mph for each
momentary switch activation of the RES/ACCEL
switch.
A ªtap downº feature is used to decelerate without
disengaging the speed control system. To decelerate
from an existing recorded target speed, momentarily
depress the COAST switch. For each switch activa-
tion, speed will be lowered approximately 1 mph.

WASHER HOSES/TUBES
DESCRIPTION
The washer plumbing consists of a small diameter
rubber hose that is routed from the barbed outlet
nipple of the washer pump/motor on the washer res-
ervoir through the engine compartment along the left
inner fender shield to a molded plastic in-line fitting
with barbed nipples near the dash panel. A second
section of washer hose passes from the engine com-
partment into the cowl plenum area through a dedi-
cated hole with a rubber grommet near the left end
of the cowl plenum panel. Beneath the cowl plenum
cover/grille panel, a molded plastic wye fitting with
barbed nipples joins the engine compartment hose to
the two washer nozzle hoses. The two washer hoses
are routed through locating clips on the underside of
the cowl plenum cover/grille panel to the two washer
nozzles.
Washer hose is available for service only as roll
stock, which must then be cut to length. The molded
plastic washer hose fittings cannot be repaired. If
these fittings are faulty or damaged, they must be
replaced.

WASHER RESERVOIR
DESCRIPTION
The molded plastic washer fluid reservoir is
secured with integral mounting tabs to keyed slots
on the left side of the radiator fan shroud in the left
front corner of the engine compartment. A bright yel-
low plastic filler cap with a rubber seal and an Inter-
national Control and Display Symbol icon for
ªWindshield Washerº and the text ªWasher Fluid
Onlyº molded into it snaps over the open end of the
filler neck. A bail strap that is integral to the cap
secures the cap to the reservoir filler neck when it is
removed for inspecting or adjusting the fluid level in
the reservoir. There are separate, dedicated holes on
the rear side of the reservoir provided for the mount-
ing of the washer/pump motor unit and the washer
fluid level switch.
The washer reservoir cannot be repaired and, if
faulty or damaged, it must be replaced. The washer
reservoir, the grommet seals for the washer pump/
motor unit and the washer fluid level switch, and the
filler cap are each available for service replacement.
OPERATION
The washer fluid reservoir provides a secure,
on-vehicle storage location for a large reserve of
washer fluid for operation of the washer system. The
washer reservoir filler neck provides a clearly
marked and readily accessible point from which to
add washer fluid to the reservoir. The washer/pump
motor unit is located in a sump area near the bottom
of the reservoir to be certain that washer fluid will
be available to the pump as the fluid level in the res-
ervoir becomes depleted. The washer fluid level
switch is mounted just above the sump area of the
reservoir so that there will be adequate warning to
the vehicle operator that the washer fluid level is
low, before the washer system will no longer operate.
REMOVAL
(1) Disconnect and isolate the battery negative
cable.
(2) Drain the engine cooling system. (Refer to 7 -
