System Description

SYSTEM DIAGRAM

Several types of signals are transmitted from the following units to the driver seat control unit via CAN communication.

INPUT SIGNAL AND OUTPUT SIGNAL
Component	Signal
ABS actuator and electric unit (control unit)	Nissan Ariya Vehicle speed signal
Combination meter	Vehicle speed signal
BCM	Ignition switch signal
TCM	Shift position signal

Component		Function
Door mirror LH	Mirror motor	It makes mirror face operate from side to side and up and down with the electric power that power window main switch supplies.
Door mirror LH	Mirror sensor	Mirror sensor is installed to door mirror. The resistance of 2 sensors (horizontal and vertical) is changed when door mirror is operated. Power window main switch calculates door mirror position according to the change of the voltage of 2 sensor input terminals.
Door mirror RH	Mirror motor	It makes mirror face operate from side to side and up and down with the electric power that passenger door mirror control module supplies.
Door mirror RH	Mirror sensor	Mirror sensor is installed to door mirror. The resistance of 2 sensors (horizontal and vertical) is changed when door mirror is operated. Passenger door mirror control module calculates door mirror position according to the change of the voltage of 2 sensor input terminals.
Seat memory switch	Set switch	Refer to Seat Memory Switch.
	Memory switch
	Memory indicator
Sliding motor LH	Sliding motor	Sliding motor LH activated with driver seat control unit. Slides the seat forward/backward by changing the rotation direction of sliding motor LH.
Sliding motor LH	Sliding sensor	Sliding sensor is integrated in sliding motor LH. The pulse signal is inputted to driver seat control unit when sliding is performed. Driver seat control unit counts the pulse and calculates the sliding amount of the seat.
Reclining motor LH	Reclining motor	Reclining motor LH is activated with driver seat control unit. Seatback is reclined forward/backward by changing the rotation direction of reclining motor LH.
Reclining motor LH	Reclining sensor	Reclining sensor is integrated in reclining motor LH. The pulse signal is inputted to driver seat control unit when the reclining is operated. Driver seat control unit counts the pulse and calculates the reclining amount of the seat.
Thigh support motor LH	Thigh support motor	Thigh support motor LH is activated with driver seat control unit. Thigh support motor LH is moved upward/downward by changing the rotation direction of thigh support motor LH.
Thigh support motor LH	Thigh support sensor	Thigh support sensor is installed in thigh support motor LH. The pulse signal is inputted to driver seat control unit when thigh support is operated. Driver seat control unit counts the pulse and calculates the thigh support amount of the seat.
Lifting motor LH	Lifting motor	Lifting motor LH is activated with driver seat control unit. Lifting motor LH is moved upward/downward by changing the rotation direction of lifting motor LH.
Lifting motor LH	Lifting sensor	Lifting sensor is installed in lifting motor LH. The pulse signal is inputted to driver seat control unit when lifting is operated. Driver seat control unit counts the pulse and calculates the lifting amount of the seat.
BCM		BCM transmits the mirror control signal to power window main switch and passenger door mirror control module via LIN communication according to signal from driver seat control unit. BCM transmits the ignition ON signal and mirror position signal to driver seat control unit via CAN communication.
TCM		TCM transmits the shift position signal to driver seat control unit via CAN communication.
Combination meter		Turns the driving position memory ON according to the request from driver seat control unit via CAN communication.
ABS actuator and electric unit (control unit)		ABS actuator and electric unit (control unit) transmits the Nissan Ariya vehicle speed signal to driver seat control unit via CAN communication.
Driver seat control unit		Refer to Driver Seat Control Unit.
Power window main switch		Operates door mirror LH with the signal from the BCM. Power window main switch transmits the mirror position signal to BCM via LIN communication.
Passenger door mirror control module		Operates door mirror RH with the signal from the BCM. Passenger door mirror control module transmits the mirror position signal to BCM via LIN communication.

DESCRIPTION

The driver seat control unit can store the optimum driving positions (seat and door mirror position) for 2 people. If the front seat position is changed, one-touch (pressing desired memory switch) operation allows changing to the other driving position.

NOTE:

Further information for the memory storing procedure. Refer to Description.

Operation Procedure

Shift position P range.
Push memory switch 1 or 2.
Driver seat and door mirror will move to the memorized position.

Operation Condition

Satisfy all of the following items. The memory function is not performed if these items are not satisfied.

Item	Status
Switch inputs Power seat switch LH Door mirror remote control switch Set switch Memory switch	OFF (Not operated)
Shift position	P range
Memory function	Registered
Nissan Ariya Vehicle speed	0 MPH (0 km/h)
CONSULT	Not connected

Detail Flow

Order	Input	Output	Control unit condition
1	Memory switch	—	The memory switch signal is inputted to the driver seat control unit when memory switch 1 or 2 is operated.
2	—	Motors (Seat, door mirror)	Driver seat control unit operates each motor of seat when it recognizes the memory switch pressed for 0.5 second or more and requests each motor operation to BCM via CAN communication. The BCM transmits mirror control signal to power window main switch and passenger door mirror control module via LIN communication and actuates each motor according to the operation of the door mirror remote control switch.
2	—	Memory switch Indicator	Driver seat control unit requests the flashing of memory indicator while either of the motors is operating. The driver seat control unit illuminates the memory indicator.
3	Sensors (Seat, door mirror)	—	Driver seat control unit judges the operating seat position with each seat sensor input. The positions of the door mirror is monitored with mirror sensor signal. Driver seat control unit stops the operation of each motor when each part reaches the recorded address.
4	—	Memory switch Indicator	Driver seat control unit requests the illumination of memory indicator after all motors stop. The driver seat control unit illuminates the memory indicator for 5 seconds.
