2000 DODGE NEON vacuum

On most vehicles another resistor has been added
to the at rest circuit causing the PCM to never see 5
volts. This was done for diagnostic purposes. If the
switch circuit should open (bad connection) then the
PCM will see the 5 volts and know the circuit is bad.
The PCM will then set an open circuit fault.
STOP LAMP SWITCH
DESCRIPTION
The switch is mounted on the brake pedal mount-
ing bracket under the instrument panel.
OPERATION
Vehicles equipped with the speed control option use
a dual function stop lamp switch. The PCM monitors
the state of the dual function stop lamp switch. Refer
to the Brake section for more information on stop
lamp switch service and adjustment procedures.
The brake switch is equipped with three sets of
contacts, one normally open and the other two nor-
mally closed (brakes disengaged). The PCM sends a
12 volt signal to one of the normally closed contacts
in the brake switch, which is connected to a ground.
With the contacts closed, the 12 volt signal is pulled
to ground causing the signal to go low. The low volt-
age signal, monitored by the PCM, indicates that the
brakes are not applied. When the brakes are applied,
the contacts open, causing the PCM's output voltage
to go high, disengaging the speed control also
grounding the dump solenoid.
The second set of normally closed contacts is sup-
plied battery voltage any time speed control is
selected. From the brake switch, current is routed to
the speed control servo solenoids. The speed control
solenoids (vacuum, vent and dump) are provided this
current any time the speed control is ON and the
brakes are disengaged. When the driver applies the
brakes, the contacts open and current is interrupted
to the solenoids. The normally open contacts are fed
battery voltage. When the brakes are applied, battery
voltage is supplied to the stop lamps.
SERVO CABLE
DESCRIPTION
The speed control servo cable is connected between
the speed control vacuum servo diaphragm and the
throttle body control linkage.
OPERATION
This cable causes the throttle control linkage to
open or close the throttle valve in response to move-
ment of the vacuum servo diaphragm.
VACUUM RESERVOIR
OPERATION
The reservoir stores engine vacuum in the reser-
voir. When engine vacuum drops, as in climbing a
grade while driving, the reservoir supplies the vac-
uum needed to maintain proper speed control opera-
tion. The vacuum reservoir cannot be repaired and
must be replaced if faulty.
VEHICLE SPEED SENSOR
The Vehicle Speed Sensor (VSS) is a pulse genera-
tor mounted to an adapter near the transmission out-
put shaft. The sensor is driven through the adapter
by a speedometer pinion gear. The VSS pulse signal
to the speedometer/odometer is monitored by the
PCM speed control circuitry to determine vehicle
speed and to maintain speed control set speed.

DESCRIPTION AND OPERATION
WINDSHIELD WASHER NOZZLE(S)
This model is equipped with two hood mounted
washer nozzles. Each nozzle emits two streams into the
wiper pattern (Fig. 1). If the nozzle performance is
unsatisfactory they can be adjusted. To adjust insert a
pin into the nozzle ball and move to proper pattern (Fig.
2). The right and left nozzles are identical.
WINDSHIELD WASHER SYSTEM
All models are equipped with electrically operated
windshield washer pumps. The wash function can be
accessed in the OFF position of the wiper control
switch. Holding the wash button depressed when the
switch is in the OFF position will operate the wipers
and washer motor pump continuously until the
washer button is released. Releasing the button will
stop the washer pump but the wipers will complete
the current wipe cycle. Followed by an average of two
more wipe cycles (61) before the wipers park and the
module turns off.
The electric pump assembly is mounted directly to
the reservoir. A permanently lubricated motor is cou-
pled to a rotor type pump. Fluid, gravity fed from the
reservoir, is forced by the pump through rubber hoses
to the hood mounted nozzles which direct the fluid
streams to the windshield.
The pump and reservoir are serviced as separate
assemblies (Fig. 3).

29 in. lbs.) torque.
WINDSHIELD WASHER PUMP
REMOVAL
(1) Raise vehicle on hoist.
(2) Disconnect the wire connector from the reser-
voir pump.
(3) Disconnect the washer hose at the pump and
drain the reservoir.
(4) Gently pry pump away from reservoir and out
of grommet. Care must be taken not to puncture res-
ervoir (Fig. 6).
(5) Remover rubber grommet from reservoir. If
replacing the pump, discard the old washer pump
grommet. If replacing the reservoir only, reuse the
old washer pump grommet.

DIAGNOSIS AND TESTING
AIRBAG SYSTEM
(1) Disconnect and isolate the battery negative
cable (Fig. 4).
(2) Connect the DRB llltscan tool to the Data
Link Connector (DLC), located at left side of the
steering column and at the lower edge of the lower
instrument panel (Fig. 5). Ensure that the latest ver-
sion is being used.
(3) Turn the ignition key to ON position. Exit vehi-
cle with the DRB llltscan tool.
(4) After checking that no one is inside the vehicle,
connect the battery negative cable.
(5) Using the DRB llltscan tool, read and record
active Diagnostic Trouble Code (DTC) data.
(6) Read and record any stored DTC's.
(7) Refer to the proper Body Diagnostic Procedures
Manual if any DTC's are found in Step 5 or Step 6.
(8) Erase stored DTC's if there are no active
DTC's. If problems remain, DTC's will not erase.
Refer to the proper Body Diagnostic Procedures Man-
ual to diagnose the problem.If airbag warning
lamp either fails to light, or goes on and stays
on, there is a system malfunction. Refer to the
proper Body Diagnostic Procedures Manual to
diagnose the problem.
SERVICE PROCEDURES
CLEAN UP PROCEDURE
Roll of fold the driver side airbag towards the
steering wheel and tape the airbag module cover over
deployed bag.
Roll or fold the passenger airbag towards the
instrument panel surface and close the door over the
folded bag. Then tape the door shut.
Use a vacuum cleaner to remove any residual pow-
der from the vehicle interior. Work from the outside
in to avoid kneeling or sitting in a contaminated
area. Vacuum the heater and A/C outlets as well. If
the heater or air conditioner was in RECIRC mode at
time of airbag deployment, operate blower motor on
low speed and vacuum powder residue expelled from
the heater and A/C outlets. Multiple vacuum cleaning
may to necessary to decontaminate the interior of the
vehicle.
NOTE: Dispose deployed airbag properly, contact
dealer or government agency for disposal recom-
mendations.
SERVICE OF DEPLOYED AIRBAG MODULE
