INPUT SIGNAL AND OUTPUT SIGNAL

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

Component	Signal
ABS actuator and electric unit (control unit)	Vehicle speed signal
Combination meter	Vehicle speed signal
IPDM E/R	Detention switch signal
BCM	Ignition switch signal
TCM	Shift position signal

System Description

OUTLINE

The driver seat control unit can store the optimum driving positions (seat, steering column 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:

For further information for the memory storage procedure, refer to the appropriate service information.

OPERATION PROCEDURE

Ignition switch ON.
Press desired memory switch.
Front seat LH, steering column 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	Request status
Switch inputs Power seat switch LH ADP steering switch Door mirror remote control switch Set switch Memory switch	OFF(Not operated)
CVT selector lever	P position
Memory function	Registered
Vehicle speed	0 MPH (0 km/h)
CONSULT	Not connected

However, the memory operation can be performed for 45 seconds after opening the front door LH (front door switch LH OFF →ON) even if the ignition switch is OFF.

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. Memory switch signal is inputted to automatic drive positioner control unit via UART communication.
2	-	Motors(seat, steering column, door mirror)	Driver seat control unit operates each motor of seat when it recognizes the memory switch pressed and requests each motor operation to automatic drive positioner control unit via UART communication. The automatic drive positioner control unit operates each motor.
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, steering column, door mirrors)	-	Driver seat control unit judges the operating seat position with each seat sensor input. The positions of the steering column and outside mirrors are monitored with each 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.
