MULTI-FUNCTION SWITCH
DESCRIPTION
The multi-function switch is secured to the upper
steering column housing at the top of the steering
column, just behind the steering wheel (Fig. 15). The
visible parts of the multi-function switch are the turn
signal control stalk w/exterior lighting controls that
extends through a dedicated opening in the left side
of the upper steering column shrouds, the windshield
wiper/washer stalk that extends through a dedicated
opening in the right side of the upper steering col-
umn shrouds, and the hazard warning switch push
button that protrudes through an opening in the
upper steering column shroud on the top of the steer-
ing column. The remainder of the switch, its mount-
ing provisions, and its electrical connections are all
concealed beneath the steering column shrouds. The
multi-function switch control stalk has both nomen-
clature and International Control and Display Sym-
bol graphics applied to it, which identify its many
functions. An International Control and Display Sym-
bol icon for “Hazard Warning” 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 connector receptacle with
up to twenty 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 multi-function switch supports the following
functions and features:
• Continuous Wipe Modes - The control knob of
the multi-function switch provides two continuous
wipe switch positions, low speed or high speed.
• Intermittent Wipe Mode - The control knob of
the multi-function switch provides an intermittent
wipe mode with multiple delay interval positions.
• Washer Mode - The control stalk of the multi-
function switch provides washer system operation
when the button is pulled towards the driver.
• Wiper Mist Mode - Mist will cycle wipers when
stalk is pulled down.
• Hazard 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.
• Exterior Lighting Control - The internal cir-
cuitry and hardware of the multi-function switch pro-
vides an input to the BCM and the BCM controls for
activation and deactivation of exterior lighting.
• Headlamp Beam Selection - The internal cir-
cuitry and hardware of the multi-function switch pro-
vides an input to the BCM and the BCM controls
detent switching for selection of the headlamp high
or low beams.
• Headlamp Optical Horn - The internal cir-
cuitry and hardware of the multi-function switch
includes momentary switching of the headlamp high
beam circuits to provides an input to the BCM and
the BCM controls the optical horn feature (some-
times referred to as flash-to-pass), which allows the
vehicle operator to momentarily flash the headlamp
high beams as an optical signaling device.
• Turn 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.
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.
HAZARD WARNING SYSTEM
The hazard warning system is identified and actu-
ated by a push button located in the multi-function
