Dakota Quad Cab 4WD V6-3.9L VIN X (2001)
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 circuitry within the switch connects the output of the wiper motor park switch to the low speed brush of the wiper motor.
-
Hazard Warning Control - The hazard warning 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 column shroud; and, when the hazard warning switch is unlatched (hazard
warning ON), the push button will be in a raised position. The multi-function switch hazard warning circuitry provides a signal to the hazard
warning sense of the combination flasher to activate or deactivate the flasher output to the hazard warning lamps.
-
Headlamp Beam Selection - The multi-function switch control stalk is pulled towards the steering wheel past a detent, then released to actuate
the headlamp beam selection switch. Each time the control 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 a ground signal output from the headlamp
switch to the appropriate low beam or high beam sense of the Central Timer Module (CTM). The CTM then controls a hard wired output to
activate the selected headlamp beams.
-
Headlamp Optical Horn - The left multi-function switch control stalk is pulled towards the steering 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 CTM high beam sense.
-
Intermittent Wipe Mode - When the multifunction switch control knob is rotated to the Delay position, the circuitry within the switch provides
a battery current 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 signals the
desired delay interval for the intermittent wiper feature.
-
Turn Signal Control - The multi-function switch control stalk actuates the turn signal switch. When the control stalk is moved in the upward
direction, 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 provides a signal to the right or left turn signal sense of the combination
flasher to activate or deactivate the flasher output to the proper turn signal lamps. The turn signal switch has a detent position in each direction
that provides turn signals with automatic cancellation, and an intermediate, momentary position in each direction that provides turn signals
only until the 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- 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 rotation 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
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.
-
Washer Mode - Pushing the control knob on the end of the multi-function switch control stalk towards the steering column provides a battery
current output through the momentary single pole, single throw washer switch circuitry to provide a washer signal input to the CTM. The CTM
then provides a battery current output to operate the washer pump/motor. If the wipers 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
operating 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 intermittent wipe interval.
