function switch. When the steering wheel is rotated during a turning maneuver, the turn signal cancel cam lobe
will contact the turn signal cancel actuator. The cancel actuator latches against the cancel cam rotation in the
direction opposite that which is signaled. If the left turn signal detent is selected, the lobe 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. When a turn signal is
activated, the multi-function switch provides a ground output on a right or left turn switch sense circuit to the
combination flasher circuitry within the hazard switch, and the combination flasher flashes the turn signal
lamps.
RIGHT CONTROL STALK
The right (wiper) control stalk of the multi-function switch operates as follows:
•
Continuous Front Wipe Modes - The control knob on the end of the multi-function switch right (wiper) control
stalk is rotated to an intermediate detent that is one detent rearward from the full forward detent to select the
low speed continuous front wiper mode, or to its full forward detent to select the high speed continuous front
wiper mode. The multi-function switch provides a resistor multiplexed output to the Body Control Module
(BCM) on a front wiper switch circuit, and the BCM responds by energizing the wiper on/off relay in the Power
Distribution Center (PDC) for the front low speed continuous wipe mode, or the wiper on/off relay and the
wiper high/low relay in the PDC for the front high speed continuous wipe mode as required.
•
Continuous Rear Wipe Mode - The control ring on the multi-function switch right (wiper) control stalk is
rotated to the most forward detent to select the continuous rear wiper mode. The multi-function switch provides
a battery voltage output to the rear wiper motor on a rear wiper on driver circuit to signal the rear wiper motor
to operate in the continuous wipe mode.
•
Front Washer Mode - The right (wiper) control stalk of the multi-function switch is pulled towards the steering
wheel to momentarily activate the washer pump in the front washer mode. The washer pump will continue to
operate in the front washer mode until the control stalk is released. The multi-function switch provides a
ground output on a washer pump sense circuit, and battery voltage on a washer pump driver circuit to ener-
gize the washer pump in the front washer mode.
•
Front Wiper Mist Mode - The right (wiper) control stalk of the multi-function switch is pushed towards the floor
to momentarily activate the front wiper motor in the mist mode. The front wiper motor will continue to operate
in the mist mode until the control stalk is released. The multi-function switch provides a resistor multiplexed
output to the Body Control Module (BCM) on a front wiper switch circuit, and the BCM responds by energizing
the wiper on/off relay in the Power Distribution Center (PDC) to operate the front wiper motor momentarily at
low speed to provide the front wiper mist mode.
•
Intermittent Front Wipe Mode - The control knob on the end of the multi-function switch right (wiper) control
stalk is rotated to one of five minor intermediate detents to select the desired intermittent front wipe delay
interval. The control knob is rotated rearward to increase the delay, or forward to decrease the delay. The
multi-function switch provides a resistor multiplexed output to the Body Control Module (BCM) on a front wiper
switch circuit, and the BCM responds by energizing the wiper on/off relay in the Power Distribution Center
(PDC) to operate the front wiper motor at the selected delay intervals.
•
Intermittent Rear Wipe Mode - The control ring on the multi-function switch right (wiper) control stalk is
rotated to the center detent to select the intermittent rear wiper mode. The multi-function switch provides a
battery voltage output to the rear wiper motor on a rear wiper intermittent driver circuit to signal the rear wiper
motor to operate in the intermittent wipe mode.
•
Rear Washer Mode - The control ring on the multi-function switch right (wiper) control stalk is rotated to either
the full forward or full rearward momentary positions to activate the washer pump in the rear washer mode.
The washer pump will continue to operate in the rear washer mode until the control ring is released. The
multi-function switch provides a ground output on a washer pump driver circuit, and battery voltage on a
washer pump sense circuit to energize the washer pump in the rear washer mode.
