Outside Mirror Description and Operation

Power Mirror System Components
The power mirror system consists of the following
components:
• Mirror direction switch—Controls the left, right, up and
down movements of the mirrors
• Mirror select switch—Allows the operator to select the
mirror to be moved
• Left outside mirror—Contains both the horizontal and
vertical mirror motors
• Right outside mirror—Contains both the horizontal
and vertical mirror motors
• POWER MIRRORS 10 A fuse—Located in the
instrument panel (I/P) fuse block and supplies power
for the power mirror system
Each of the outside power mirrors contains 2 motors.
The up-down motor operates the vertical directions and
the left-right motor operates the horizontal directions.
Each of the power mirror motors are internally circuit
breaker protected.
Power Mirror System Controls
The outside mirror switch incorporates a mirror select
switch and a 4 position mirror direction switch.
The mirror select switch allows the driver to select the
mirror to be moved by pressing the switch to L position
enabling the left outside mirror or pressing the switch to
R position enabling the right outside mirror.
The mirror direction switch is a 4 position switch that
allows the operator to move the selected mirror up,
down, left or right.
Power Mirror System Operation
The outside mirror switch receives power through the
battery positive voltage circuit from the POWER
MIRRORS 10 A fuse in the instrument panel (I/P) fuse
block. The outside mirror switch also receives a constant
ground.
The 4 positions of the direction switch have multiple
switch contacts. When not in use, the directional
contacts are isolated from any circuit. Each of the
contacts are connected to opposing sides of the
appropriate mirror motors through the selector switch.
The selector switch interrupts or completes these circuits
depending on the position of the selector switch, L or R.
If the mirror select switch is placed in the L position and
the up switch is pressed, battery voltage will be supplied
to the driver outside mirror vertical motor through the
driver mirror motor up control circuit and return to the
mirror switch through the driver mirror motor left/down
control circuit, then to ground and the mirror will move
up. If the down switch is pressed, the driver mirror motor
left/down control circuit supplies battery voltage and the
driver mirror motor up control circuit completes the path
to the mirror switch, then to ground and the mirror will
move down.
The remainder of the mirror functions operate in the
same manner as described above. Placing the mirror
direction switch in opposing positions, left/right or up/
down, will reverse the voltage polarity to the mirror
motor, utilizing the same circuits and the mirror will move
accordingly.
Automatic Day-Night Mirror Description and
Operation
Inside Rearview Mirror with the Automatic Day-
Night Feature System Components
The inside rearview mirror with the automatic day-night
feature system consist of the following component:
Inside rearview mirror
Power and Ground of the Inside Rearview
Mirror
• With the ignition ON, ignition voltage is supplied to the
mirror from the POWER SUNROOF20A fuse in the I/
P fuse block.
• Ground for the mirror is provided by G401.
Inside Rearview Mirror with the Automatic Day-
Night Feature System Operation
The inside rearview mirror uses 2 photocell sensors.
One sensor is the headlight sensor, located on the rear
side of the mirror. The headlight sensor is used to
determine light conditions present at the mirror face. The
other sensor is the ambient light sensor, located on the
front of the mirror or windshield side. The ambient light
sensor is used to determine light conditions present at
the mirror. With automatic day-night feature enabled, the
mirror uses ambient light sensor to determine the
exterior light condition. With a low light condition
detected, and a high light condition from behind at the
headlight sensor, the inside rearview mirror will
automatically darken the face of the mirror.
In the daytime, the mirror is in a normal state because of
the high light condition that is indicated by the ambient
light sensor. With the gear selector lever in the
REVERSE position, backup lamp supply voltage is
supplied as an input to the inside rearview mirror. In
night time conditions only, the mirror monitors this input
to disable the automatic day-night feature which allows
the face to gradually change to a normal state. This
allows the driver to see objects in the mirror clearly when
backing up.
