multi-function switch DODGE RAM 2001 Service User Guide

spring mechanism rotates with the steering wheel
and the cam lobes contact the cancel actuator when
it is extended from the multi-function switch. When
the steering wheel is rotated during a turning
maneuver, one of the two turn signal cancel cam
lobes will contact the turn signal cancel actuator. The
cancel actuator latches against the cancel cam rota-
tion in the direction opposite that which is signaled.
In other words, if the left turn signal detent is
selected, the lobes of the cancel cam will ratchet past
the cancel actuator when the steering wheel is
rotated to the left, but will unlatch the cancel actua-
tor as the steering wheel rotates to the right and
returns to center, which will cancel the turn signal
event and release the control stalk from the detent so
it returns to the neutral Off position.
²Washer Mode- Pushing the button on the end
of the multi-function switch control knob towards the
steering column provides a battery current output
through the momentary single pole, single throw
washer switch circuitry to operate the washer pump/
motor and provides a signal to the CTM. If the wip-
ers are not operating when the washer switch is
actuated, the CTM will operate the wiper motor for
as long as the washer switch is depressed plus about
three additional wipe cycles. If the wipers are oper-
ating in the intermittent mode when the washer
switch is actuated, the CTM will operate the wiper
motor at a fixed low speed for as long as the washer
switch is depressed plus about three additional wipe
cycles before the wipers return to the selected inter-
mittent wipe interval.DIAGNOSIS AND TESTING - MULTI-FUNCTION

ary. The rotor of the clockspring, including the turn
signal cancel cam lobes rotate with the steering
wheel.
The turn signal cancel cam is serviced as a unit
with the clockspring and cannot be repaired. If faulty
or damaged, the entire clockspring unit must be
replaced. (Refer to 8 - ELECTRICAL/RESTRAINTS/
CLOCKSPRING - REMOVAL).
OPERATION
The turn signal cancel cam has two lobes molded
into the lower surface of the clockspring rotor. When
the turn signals are activated by moving the multi-
function switch control stalk to a detent position, a
turn signal cancel actuator is extended from the
inside surface of the multi-function switch housing
toward the center of the steering column and theturn signal cancel cam. When the steering wheel is
rotated during a turning maneuver, one of the two
turn signal cancel cam lobes will contact the turn sig-
nal cancel actuator. The cancel actuator latches
against the cancel cam rotation in the direction oppo-
site that which is signaled. In other words, if the left
turn signal detent is selected, the lobes of the cancel
cam will ratchet past the cancel actuator when the
steering wheel is rotated to the left, but will unlatch
the cancel actuator as the steering wheel rotates to
the right and returns to center, which will cancel the
turn signal event and release the control stalk from
the detent so it returns to the neutral Off position.

CLOCKSPRING
DESCRIPTION
The clockspring assembly is secured with two inte-
gral plastic latches onto the steering column lock
housing near the top of the steering column, behind
the steering wheel. The clockspring consists of a flat,
round molded plastic case with a stubby tail that
hangs below the steering column and contains a con-
nector receptacle and a long pigtail wire with connec-
tor that face toward the instrument panel. Within
the plastic housing is a spool-like molded plastic
rotor with a large exposed hub. The upper surface of
the rotor hub has a large center hole, two large flats,
two auto-locking tabs, and three short pigtail wires
with connectors that face toward the steering wheel.
The lower surface of the rotor hub has two integral
turn signal cancelling cam lobes. Within the plastic
case and wound around the rotor spool is a long rib-
bon-like tape that consists of several thin copper wire
leads sandwiched between two thin plastic mem-
branes. The outer end of the tape terminates at the
connector receptacle and pigtail wire that face the
instrument panel, while the inner end of the tape
terminates at the pigtail wires on the hub of the
clockspring rotor that face the steering wheel.
Service replacement clocksprings are shipped pre-
centered and with a piece of tape covering the
engaged auto-locking tabs. The auto-locking tabs
secure the centered clockspring rotor to the clock-
spring case during shipment, but these tabs are auto-
matically disengaged once the clockspring is installed
on the steering column. (Refer to 8 - ELECTRICAL/
RESTRAINTS/CLOCKSPRING - STANDARD PRO-
CEDURE - CLOCKSPRING CENTERING).
The clockspring cannot be repaired. If the clock-
spring is faulty, damaged, or if the driver airbag has
been deployed, the clockspring must be replaced.
OPERATION
The clockspring is a mechanical electrical circuit
component that is used to provide continuous electri-
cal continuity between the fixed instrument panel
wire harness and the electrical components mountedon or in the rotating steering wheel. On this model
the rotating electrical components include the driver
airbag, the horn switch, the speed control switches,
and the remote radio switches if the vehicle is so
equipped. The clockspring case is positioned and
secured to the upper steering column lock housing by
two integral plastic latches. The connector receptacle
on the tail of the fixed clockspring housing connect
the clockspring to the vehicle electrical system
through a take out with connector from the instru-
ment panel wire harness. The lower clockspring pig-
tail on the tail of the clockspring housing connect the
clockspring driver airbag circuits to a separate take
out and connector of the instrument panel wire har-
ness located near the lower instrument panel rein-
forcement, below the steering column. The
clockspring rotor is movable and is keyed to the hub
of the steering wheel by two large flats that are
molded into the rotor hub. The two lobes on the
lower surface of the clockspring rotor hub contact a
turn signal cancel actuator of the multi-function
switch to provide automatic turn signal cancellation.
The pigtail wires on the upper surface of the clock-
spring connect the clockspring to the horn switch, the
two speed control switches, and the remote radio
switches on vehicles that are so equipped.
Like the clockspring in a timepiece, the clockspring
tape has travel limits and can be damaged by being
wound too tightly during full stop-to-stop steering
wheel rotation. To prevent this from occurring, the
clockspring must be centered when it is installed on
the steering column. Centering the clockspring
indexes the clockspring spool to the movable steering
components so that the tape can operate within its
designed travel limits. However, if the clockspring is
removed from the steering column or if the steering
shaft is disconnected from the steering gear, the
clockspring spool can change position relative to the
movable steering components and must be re-cen-
tered following completion of the service or the tape
may be damaged. Service replacement clocksprings
are shipped pre-centered and with the auto-locking
tabs engaged. A piece of tape covers the auto-locking
tabs to discourage tampering. These auto-locking
tabs should not be disengaged until the clockspring
has been installed on the steering column. If this
shipping tape is removed or damaged, or if the auto-
locking tabs are disengaged before the clockspring is
installed on a steering column, the clockspring cen-
tering procedure must be performed. (Refer to 8 -
ELECTRICAL/RESTRAINTS/CLOCKSPRING -
STANDARD PROCEDURE - CLOCKSPRING CEN-
TERING).

WIPERS/WASHERS
DESCRIPTION
An electrically operated intermittent wiper and
washer system is standard factory-installed safety
equipment on this model. The wiper and washer sys-
tem includes the following major components, which
are described in further detail elsewhere in this ser-
vice information:
²Central Timer Module- The Central Timer
Module (CTM) is located under the driver side end of
the instrument panel, inboard of the instrument
panel steering column opening. A base version of the
CTM is used on base models of this vehicle. The base
version of the CTM combines the functions of a
chime module and an intermittent wipe module in a
single unit. The high-line version of the CTM is used
on high-line vehicles. The high-line CTM provides all
of the functions of the base version of the CTM, but
also is used to control and integrate many additionalelectronic functions and features included on high-
line models. The premium version of the CTM is the
same as the high-line version, but is used only on
models equipped with the heated seat option. The
high-line and premium versions of the CTM contain
integrated circuitry, a central processing unit and the
programming to provide all of the proper wiper and
washer system features based upon the monitored
inputs. The high-line and premium CTM circuitry
monitors hard wired switch inputs, as well as mes-
sage inputs received from other vehicle electronic
modules on the Chrysler Collision Detection (CCD)
data bus network. (Refer to 8 - ELECTRICAL/ELEC-
TRONIC CONTROL MODULES/BODY CONTROL/
CENTRAL TIMER MODULE - DESCRIPTION).
²Multi-Function Switch- The multi-function
switch is secured to the left side of the steering col-
umn, just below the steering wheel. Only the control
stalk for the multi-function switch is visible, the
remainder of the switch is concealed beneath the
steering column shrouds. The multi-function switch
BR/BEWIPERS/WASHERS 8R - 1

contains all of the switches for both the wiper and
washer systems.
²Washer Fluid Level Switch- The washer fluid
level switch is located in a dedicated hole on the
lower rear side of the washer reservoir, above the
washer pump/motor unit near the left front corner of
the engine compartment.
²Washer Nozzles- The dual fluidic washer noz-
zles are secured with integral snap features to dedi-
cated openings in the cowl plenum cover/grille panel
located near the base of the windshield. The washer
plumbing fittings for the washer nozzles are con-
cealed beneath the cowl plenum cover/grille panel.
²Washer Pump/Motor- The washer pump/mo-
tor unit is located in a dedicated hole on the lower
rear side of the washer reservoir near the left front
corner of the engine compartment.
²Washer Reservoir- The washer reservoir is
secured to the left side of the radiator fan shroud in
the left front corner of the engine compartment.
²Wiper Arms- The two wiper arms are secured
to the two wiper pivots, which extend through the
cowl plenum cover/grille panel located near the base
of the windshield.
²Wiper Blades- The two wiper blades are
secured to the two wiper arms, and are parked on
the glass near the bottom of the windshield when the
wiper system is not in operation.
²Wiper Module- The wiper pivots are the only
visible components of the wiper module. The remain-
der of the module is concealed within the cowl ple-
num beneath the cowl plenum cover/grille panel. The
wiper module includes the module bracket, the single
wiper motor, the wiper linkage, and the two wiper
pivots.
²Wiper Relay- The wiper relay is located in the
Power Distribution Center (PDC) in the engine com-
partment near the battery.
Features of the wiper and washer system include
the following:
²Continuous Wipe Modes- The two-speed
wiper motor and the internal circuitry of the multi-
function switch work in concert to provide two con-
tinuous wipe cycles, low speed or high speed.
²Intermittent Wipe Mode- The internal cir-
cuitry of the multi-function switch, the CTM, and the
wiper relay work in concert to provide an intermit-
tent wipe mode with multiple delay interval selec-
tions. On models with a high-line or premium CTM,
the CTM also automatically adjusts each manually
selected delay interval to compensate for vehicle
speed.
²Washer Mode- When the washer system is
activated with the multi-function switch while the
wiper system is operating, washer fluid will be dis-
pensed onto the windshield glass through the washernozzles for as long as the washer pump/motor is
energized.
²Wipe-After-Wash Mode- The internal circuitry
of the CTM provides a wipe-after-wash feature
which, if the wipers are turned Off, will operate the
washer pump/motor and the wipers for as long as the
washer system is activated, then provide several
additional wipe cycles after the washer system is
deactivated before parking the wiper blades near the
base of the windshield.
Hard wired circuitry connects the wiper and
washer system components to the electrical system of
the vehicle. These hard wired circuits are integral to
several wire harnesses, which are routed throughout
the vehicle and retained by many different methods.
These circuits may be connected to each other, to the
vehicle electrical system and to the wiper and washer
system components through the use of a combination
of soldered splices, splice block connectors, and many
different types of wire harness terminal connectors
and insulators. Refer to the appropriate wiring infor-
mation. The wiring information includes wiring dia-
grams, proper wire and connector repair procedures,
further details on wire harness routing and reten-
tion, as well as pin-out and location views for the
various wire harness connectors, splices and grounds.
OPERATION
The wiper and washer system is intended to pro-
vide the vehicle operator with a convenient, safe, and
reliable means of maintaining visibility through the
windshield glass. The various components of this sys-
tem are designed to convert electrical energy pro-
duced by the vehicle electrical system into the
mechanical action of the wiper blades to wipe the
outside surface of the glass, as well as into the
hydraulic action of the washer system to apply
washer fluid stored in an on-board reservoir to the
area of the glass to be wiped. When combined, these
components provide the means to effectively main-
tain clear visibility for the vehicle operator by remov-
ing excess accumulations of rain, snow, bugs, mud, or
other minor debris from the outside windshield glass
surface that might be encountered while driving the
vehicle under numerous types of inclement operating
conditions. The vehicle operator initiates all wiper
and washer system functions with the multi-function
switch control stalk that extends from the left side of
