HEADLAMP
DESCRIPTION
Headlamps on the Ram Pick-Up are modular in
design. The turn/park lamp module is incorporated
into the headlamp module. The module contains two
bulbs; a dual filament headlamp bulb, and a dual fil-
ament turn/park bulb. The Sport headlamp module
has two separate bulbs for the headlamp illumina-
tion.
OPERATION
Headlamps and parking lamps are controlled by
the headlamp switch. The multifunction switch
mounted on the steering column controls the high
beam function, and the turn signal function.
DIAGNOSIS AND TESTING - HEADLAMP
A good ground is necessary for proper lighting
operation. Grounding is provided by the lamp socket
when it comes in contact with the metal body, or
through a separate ground wire.
Always begin any diagnosis by testing all of the
fuses and circuit breakers in the system. For com-
plete circuit diagrams, refer to the appropriate wir-
ing information. The wiring information includes
wiring diagrams, proper wire and connector repair
procedures, details of wire harness routing and
retention, connector pin-out information and location
views for the various wire harness connectors, splices
and grounds.

MULTI-FUNCTION SWITCH
DESCRIPTION
The multi-function switch is secured with two
screws to the left side of the upper steering column
housing at the top of the steering column, just below
the steering wheel (Fig. 24). The only visible parts of
the multi-function switch are the control stalk that
extends through a dedicated opening in the left side
of the upper steering column shrouds, and the haz-
ard warning switch push button that protrudes
through an opening in the upper steering columnshroud on the top of the steering column. The
remainder of the switch, its mounting provisions, and
its electrical connections are all concealed beneath
the steering column shrouds. The multi-function
switch control stalk has both nomenclature and
International Control and Display Symbol graphics
applied to it, which identify its many functions. An
International Control and Display Symbol icon for
ªHazard Warningº is applied to the top of the hazard
warning switch push button.
The switch housing and its controls are constructed
of molded black plastic. A single connector receptacle
with up to twenty-four terminals is located on the
back of the switch housing and connects the switch
to the vehicle electrical system through a take out
and connector of the instrument panel wire harness.
The connector receptacle also has a threaded recep-
tacle for a screw, which secures the wire harness con-
nector to the switch connector receptacle.
The multi-function switch supports the following
functions and features:
²Continuous Wipe Modes- The control knob of
the multi-function switch provides two continuous
wipe switch positions, low speed or high speed.
²Hazard Warning Control- The internal cir-
cuitry and hardware of the multi-function switch pro-
vide detent switching for activation and deactivation
of the hazard warning system.
²Headlamp Beam Selection- The internal cir-
cuitry and hardware of the multi-function switch pro-
vide detent switching for selection of the headlamp
high or low beams.
²Headlamp Optical Horn- The internal cir-
cuitry and hardware of the multi-function switch

MARKER LAMP (Continued)

includes momentary switching of the headlamp high
beam circuits to provide an optical horn feature
(sometimes referred to as flash-to-pass), which allows
the vehicle operator to momentarily flash the head-
lamp high beams as an optical signalling device.
²Intermittent Wipe Mode- The control knob of
the multi-function switch provides an intermittent
wipe mode with multiple delay interval positions.
²Turn Signal Control- The internal circuitry
and hardware of the multi-function switch provide
both momentary non-detent switching and detent
switching with automatic cancellation for both the
left and right turn signals.
²Washer Mode- A button on the end of the con-
trol stalk of the multi-function switch provides
washer system operation when the button is
depressed towards the steering column.
The multi-function switch cannot be adjusted or
repaired. If any function of the switch is faulty, or if
the switch is damaged, the entire switch unit must
be replaced.
OPERATION
The multi-function switch uses conventionally
switched outputs and a variable resistor to control
the many functions and features it provides using
hard wired circuitry. The switch is grounded at all
times through a single wire take out with an eyelet
terminal connector of the instrument panel wire har-
ness that is secured by a nut to a ground stud
located on the instrument panel armature, just above
and to the left of the glove box opening. When the
ignition switch is in the Accessory or On positions,
battery current from a fuse in the Junction Block
(JB) is provided through a fused ignition switch out-
put (run-acc) circuit. Following are descriptions of
the how the multi-function switch operates to control
the many functions and features it provides:
²Continuous Wipe Modes- When the control
knob of the multi-function switch is rotated to the
High or Low positions, the circuitry within the
switch provides a battery current output directly to
the high or low speed brush of the wiper motor.
When the control knob is in the Off position, the cir-
cuitry within the switch connects the output of the
wiper motor park switch to the low speed brush of
the wiper motor.
²Hazard Warning Control- The hazard warn-
ing push button is pushed down to unlatch the
switch and activate the hazard warning system, and
pushed down again to latch the switch and turn the
system off. When the hazard warning switch is
latched (hazard warning off), the push button will be
in a lowered position on the top of the steering col-
umn shroud; and, when the hazard warning switch is
unlatched (hazard warning on), the push button willbe in a raised position. The multi-function switch
hazard warning circuitry simultaneously provides a
signal to the hazard warning sense of the combina-
tion flasher to activate or deactivate the flasher out-
put, and directs the output of the flasher to the
hazard warning lamps.
²Headlamp Beam Selection- The multi-func-
tion switch control stalk is pulled towards the steer-
ing wheel past a detent, then released to actuate the
headlamp beam selection switch. Each time the con-
trol stalk is actuated in this manner, the opposite
headlamp mode from what is currently selected will
be activated. The internal circuitry of the headlamp
beam selection switch directs the output of the head-
lamp switch through hard wired circuitry to activate
the selected headlamp beam.
²Headlamp Optical Horn- The left multi-func-
tion switch control stalk is pulled towards the steer-
ing wheel to just before a detent, to momentarily
activate the headlamp high beams. The high beams
will remain illuminated until the control stalk is
released. The internal circuitry of the headlamp
beam selection switch provides a momentary ground
path to the headlamp high beams.
²Intermittent Wipe Mode- When the multi-
function switch control knob is rotated to the Delay
position, the circuitry within the switch connects the
output of the wiper motor relay to the low speed
brush of the wiper motor and provides a battery cur-
rent signal to the Central Timer Module (CTM). If
the Delay mode is selected, the control knob can then
be rotated to multiple minor detent positions, which
actuates a variable resistor within the switch and
provides a hard wired output to the CTM that sig-
nals the desired delay interval for the intermittent
wiper feature.
²Turn Signal Control- The multi-function
switch control stalk actuates the turn signal switch.
When the control stalk is moved in the upward direc-
tion, the right turn signal circuitry is activated; and,
when the control stalk is moved in the downward
direction, the left turn signal circuitry is activated.
The multi-function switch turn signal circuitry simul-
taneously provides a signal to the turn signal sense
of the combination flasher to activate or deactivate
the flasher output, and directs the output of the
flasher to the proper turn signal lamps. The turn sig-
nal switch has a detent position in each direction
that provides turn signals with automatic cancella-
tion, and an intermediate, momentary position in
each direction that provides turn signals only until
the left multi-function switch control stalk is
released. When the control stalk is moved to a turn
signal switch detent position, the cancel actuator
extends toward the center of the steering column. A
turn signal cancel cam that is integral to the clock-
8L - 24 LAMPS/LIGHTING - EXTERIORBR/BE
MULTI-FUNCTION SWITCH (Continued)

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
