UART communication.

• It performs memory function after receiving the door unlock sig-

nal from BCM.

• Operates each motor of seat to the registered position.
• Requests the operation of steering column and door mirror to

automatic drive positioner control unit

• Operates the specific seat motor with the signal from power seat

switch.

• Transmits the ignition switch signal (ACC/ON) via UART com-

munication to automatic driver positioner control unit.

Automatic drive positioner control unit

• It communicates with driver seat control unit via UART commu-

nication.

• Performs various controls with the instructions of driver seat

control unit.

• Performs the controls of tilt & telescopic (if equipped), door mir-

ror and seat memory switch.

• Operates steering column (if equipped) and door mirror with the

signal from the driver seat control unit

BCM

Recognizes the following status and transmits it to driver seat con-
trol unit via CAN communication.
• Handle position: LHD
• Driver door: OPEN/CLOSE
• Ignition switch position: ACC/ON
• Door lock: UNLOCK (with Intelligent Key or driver side door re-

quest switch operation)

• Key ID
• Starter: CRANKING/OTHER

TCM

The following signals are transmitted to driver seat control unit via
CAN communication.
• Shift position signal (P range)
• Identification of transmission: CVT

Combination meter

Transmits the vehicle speed signal to driver seat control unit via
CAN communication.

CVT shift selector (Detention switch)

• Detention switch is installed on CVT shift selector. It is turned

OFF when CVT shift selector is in P position.

• Driver seat control unit judges that CVT shift selector is in P po-

sition if continuity does not exist in this circuit.

unit when telescopic switch is operated.

Seat memory switch

Set switch

It is used for registration and setting change of driving position and
Intelligent Key interlock function.

Seat memory switch

• The maximum 2 driving positions can be registered by memory

switch 1 to 2.

• Driving position is set to the registered driving position when

memory switch is pressed while operation conditions are satis-
fied.

Seat memory indicator

Memory indicator indicates the status of auto driving position sys-
tem by turning ON or blinking.

Power seat switch

Sliding switch

• Sliding switch is equipped to power seat switch on seat cushion

side surface.

• The operation signal is input to driver seat control unit when slid-

ing switch is operated.

Reclining switch

• The operation signal is input to driver seat control unit when re-

clining switch is operated.

• The operation signal is input to driver seat control unit when re-

clining switch is operated.

Lifting switch (front)

• Lifting switch (front) is equipped to power seat switch on seat

cushion side surface.

• The operation signal is input to driver seat control unit when lift-

ing switch (front) is operated.

Lifting switch (rear)

• Lifting switch (rear) is equipped to power seat switch on seat

cushion side surface.

• The operation signal is input to driver seat control unit when lift-

ing switch (rear) is operated.

Door mirror (driver side/
passenger side)

Door mirror motor

It makes mirror face operate from side to side and up and down
with the electric power that automatic drive positioner control unit
supplies.

Mirror sensor

• Mirror sensor is installed to door mirror.
• The resistance of 2 sensors (horizontal and vertical) is changed

when door mirror is operated.

• Automatic drive positioner control unit calculates door mirror po-

sition according to the change of the voltage of 2 sensor input
terminals.

COMPONENT PARTS

Tilt motor (if equipped)

Tilt motor

• Tilt motor is installed to steering column assembly.
• Tilt motor is activated with automatic drive positioner control unit.
• Steering column is tilted upward/downward by changing the ro-

tation direction of tilt motor.

Tilt sensor

• Tilt sensor is integrated in tilt motor.
• The resistance of tilt sensor is changed according to the up/

down position of steering column.

• The terminal voltage of automatic drive positioner control unit

will be changed according to a change of tilt sensor resistance.

• Automatic drive positioner control unit calculates the tilt position

from the voltage.

Telescopic motor (if
equipped)

Telescopic motor

• Telescopic motor is installed to steering column assembly.
• Telescopic motor is activated with automatic drive positioner

control unit.

• Compresses steering column by changing the rotation direction

of telescopic motor.

Telescopic sensor

• Telescopic sensor is integrated in telescopic motor.
• The resistance of telescopic sensor is changed according to the

forward/backward position of steering column.

• The terminal voltage of automatic drive positioner control unit

will be changed according to a change of telescopic sensor re-
sistance.

• Automatic drive positioner control unit calculates the telescopic

position from the voltage.

Sliding motor LH

Sliding motor LH

• Seat sliding motor LH is installed to the seat cushion frame.
• Seat sliding motor LH is activated with driver seat control unit.
