2000 DODGE NEON combination switch

DESCRIPTION AND OPERATION
BASE BRAKE SYSTEM OPERATION
When a vehicle needs to be stopped, the driver
applies the brake pedal. The brake pedal pushes the
input rod of the power brake booster into the booster.
The booster uses vacuum to ease pedal effort as force
is transferred through the booster to the master cyl-
inder. The booster's output rod pushes in the master
cylinder's primary and secondary pistons applying
hydraulic pressure through the chassis brake tubes
and proportioning valves (rear only) to the brakes at
each tire and wheel assembly.
Front disc brakes control the braking of the front
wheels; rear braking is controlled by rear drum
brakes as standard equipment. Rear disc brakes and
an antilock brake system (ABS) with traction control
are optional.
The hydraulic brake system is diagonally split on
both the non-antilock and antilock braking systems.
This means the left front and right rear brakes are
on one hydraulic circuit and the right front and left
rear are on the other.
Vehicles equipped with the optional antilock brake
system (ABS) use a system designated Mark 20e.
This system shares most base brake hardware used
on vehicles without ABS. A vehicle equipped with
ABS, however, uses a different master cylinder and
brake tubes. Also included in the ABS system is an
integrated control unit (ICU) and four wheel speed
sensors. These components are described in detail in
the ANTILOCK BRAKE SYSTEM section in this
group of the service manual. All vehicles with ABS
come standard with four-wheel-disc brakes and trac-
tion control.
The parking brakes are hand-operated. When
applied, the parking brake lever pulls on cables that
actuate brake shoes at each rear wheel. The parking
brake lever has an automatic adjusting feature that
takes up any excessive slack in the parking brake
cable system.
BASE BRAKE SYSTEM COMPONENTS
BRAKE PEDAL
A suspended-type brake pedal is used on this vehi-
cle. The pedal pivots on a shaft mounted in the pedal
support bracket under the instrument panel. The
pedal connects to the power brake booster input rod
and pushes it in when the pedal is applied.
The brake pedal and it's pad are serviceable sepa-
rately.
POWER BRAKE BOOSTER
There are two different power brake booster
designs, although externally they appear the same.
All vehicles use a 205 mm tandem diaphragm power
brake booster. The two boosters are internally tuned
differently depending on whether the vehicle is
equipped with the standard front disc/rear drum
brake combination or the optional front disc/rear disc
(four-wheel disc) brake combination. If the power
brake booster requires replacement, be sure it is
replaced with the correct part.
The power brake booster can be identified by the
tag attached to the body of the booster assembly (Fig.
1). This tag contains the following information: The
production part number of the power brake booster,
the date it was built and who manufactured it.
The power brake booster reduces the amount of
force required by the driver to obtain the necessary
hydraulic pressure to stop the vehicle.
The power brake booster is vacuum-operated. The
vacuum is supplied from the intake manifold on the
engine through the power brake booster check valve
(Fig. 2).
As the brake pedal is depressed, the power booster
input rod moves forward. This opens and closes
valves in the power brake booster, allowing atmo-
spheric pressure to enter on one side of a diaphragm.
Engine vacuum is always present on the other side.
This difference in pressure forces the output rod of
the power booster out against the primary piston of
the master cylinder. As the pistons in the master cyl-
inder move forward, hydraulic pressure is created in
the brake system.

PLTURN SIGNAL and HAZARD WARNING SYSTEMS 8J - 1

The integrated switch assembly is mounted to the
left hand side of the steering column. When the
driver wishes to signal his intentions to change direc-
tion of travel, he moves the lever upward to cause
the right signals to flash and downward to cause the
left signals to flash. After completion of a turn the
system is deactivated automatically. As the steering
wheel returns to the straight ahead position, a can-
celing cam molded to the clockspring mechanism
comes in contact with the cancel actuator on the turn
signal multi-function switch assembly. The cam lobe,
pushing on the cancel actuator, returns the switch to
the off position.
If only momentary signaling such as indication of a
lane change is desired, the switch is actuated to a
left or right intermediate detent position. In this
position the signal lamps flash as described above,
but the switch returns to the OFF position as soon as
the lever is released.
When the system is activated, one of two indicator
lamps mounted in the instrument cluster flashes in
unison with the turn signal lamps, indicating to the
driver that the system is operating.
DESCRIPTION AND OPERATION
HAZARD WARNING SYSTEM
The hazard warning system is actuated by a push
button located in the muti-function switch (Fig. 1) on
the top of the steering column between the steering
wheel and the instrument panel. The hazard switch
is identified with a double triangle on front of the
button.
HEADLAMP SWITCH
The headlamp switch is part of the Multi-Function
Switch (Fig. 1). Refer to Multi-Function Switch Diag-
nosis and Testing, Turn Signal and Hazard Warning
Flasher Diagnosis table in this section.
COMBINATION FLASHER
The turn signal flasher and the hazard warning
flasher are combined into one unit called a combina-
tion flasher (combo-flasher). The combo- flasher con-
trols the flashing of the hazard warning system and
the turn signal system. An inoperative bulb or incom-
plete turn signal circuit will cause the flasher rate to
double.
The combo-flasher is located on the back of the
multi-function switch (Fig. 2). The combo-flasher is
black in color and has a dampener material wrapped
on it.

REMOVAL AND INSTALLATION
COMBINATION FLASHER
The flasher is mounted to the back side of the
multi-function switch (Fig. 2). To gain access the
upper steering column shroud must be removed.
Refer to Group 8E Instrument Panel Systems, Steer-
ing Column Shroud Removal and Installation. The
flasher can be removed by pulling it toward the
instrument cluster (forward). The flasher is serviced
separately from the multi-function switch.
MULTI-FUNCTION SWITCH
REMOVAL
(1) Disconnect and isolate the battery negative
cable (Fig. 6).
(2) Remove both upper and lower steering column
shrouds. Refer to Group 8E Instrument Panel Sys-
tems, Steering Column Shroud Removal and Instal-
lation.
