Power Seat System Components
The power seat system for the driver and passenger
consists of the following components:
S
Power Seat Switch
S
Seat Horizontal Motor
S
Seat Front Vertical Motor
S
Seat Rear Vertical Motor
S
Seat Recliner Motor
S
Passenger Seat Module
Power Seat System Operation
Two power seat systems are available in this vehicle.
The AR9 system is deluxe heated bucket seats with
driver memory, and utilizes driver and passenger seat
control modules. For the driver memory seat operation
refer to Memory Seats Description and Operation . The
A51 system is 8 way power adjustable bucket seats
with power lumbar, and all of the adjuster motors are
directly controlled through the switch assemblies.
A51 Power Seats
Battery voltage is supplied to the power seat switch
through the power seat circuit breaker. While the seat
adjuster switches are in an inactive state the switch
contacts are closed to the power seat switch ground
circuit. When a power seat switch is pressed to an
active state the switch contact is closed to the battery
voltage supply circuit. Each seat adjuster motor is
controlled by the power seat switch through 2 motor
control
circuits.
The
seat
adjuster
motors
are
bidirectional and the direction of adjuster motor rotation
is determined by which of the adjuster motor control
circuits is switched to battery voltage while the other
remains grounded.
AR9 Front Passenger Seat
Battery voltage is supplied to the passenger seat
module through the power seat circuit breaker. The
passenger seat module supplies the seat adjuster
switch assembly with a battery positive reference
voltage. While the seat adjuster switches are in an
inactive state the switch contacts are closed to the
adjuster switch ground circuit. When a seat adjuster
switch is pressed to an active state the switch contact is
closed to the reference voltage circuit. Battery voltage
on a switch signal circuit indicates to the seat module
the switch status is active. Each seat adjuster motor is
controlled by the seat module through 2 motor control
circuits. While the seat adjuster motors are in an
inactive state the motor control circuits are closed to
ground circuit contacts within the seat module. The seat
module operates the seat adjuster motors by switching
one of a motor’s control circuits to battery voltage. The
seat adjuster motors are bidirectional and the direction
of adjuster motor rotation is determined by which of the
adjuster motor control circuits is switched to battery
voltage while the other remains grounded.
