DESCRIPTION

An optimal seat position set by a driver can be memorized in P/seat unit by memory SW and position SW, which
enables restoration of seat position set by the driver despite seat adjustments.
Furthermore, data is transmitted between P/seat and IPM, DDM, ADM, RAM, FAM, CLUSTER through CAN BUS.
Seat position presets cannot be recalled while driving. An emergency stop function is provided; additional functions are
described below.

1. It conducts manual operation of seat by CAN BUS data transmitted by DDM as well as that of adjustable pedal by

CAN BUS data transmitted by IPM received when operating SW manually.

2. Manual SW behavior when communication stops (back-up behavior)

a. Slide front/rear

b. Recline front/rear

c. Position control of slide motor is possible by manual SW even in case of congestion in CPU or removal of a

fuse for P/seat unit B.

3. 2 memory locations are provided for storing seat, outside mirror, and adjustable pedal presets.

4. The driver seat can be set to slide rearward when the ignition key is removed, and forward when the key is

inserted.

5. 2 additional presets for seat, mirror, and adjustable pedal position can be stored with the RKE transmitter.

OPERATION

MANUAL OPERATION

Manual operation of the driver seat and adjustable pedals is possible provided the transaxle is in 'P' range and the
vehicle speed is 0 MPH. Operation of the manual controls overrides any automatic operation commanded via CAN.

MEMORY OPERATION

1. Pressing the 'M' button on the control panel will place the system into memory storage mode and will result in a

single pulse from the output buzzer.

2. If one of the memory location buttons is pressed and held within 5 seconds of pressing the 'M' button, the output

buzzer will pulse twice to indicate successful storage of seat, mirror, and adjustable pedal positions.

3. The ignition switch must be in the RUN or START position, the vehicle speed must be 0 MPH, and the transaxle

must be in 'P' range to store memory presets.

4. Pressing the 'M' button while recalling a stored preset will halt the preset recall operation.

5. Memory will be cleared if battery is removed.

MEMORY REPLAY OPERATION

1. Pressing one of the memory location buttons will result in the driver seat, outside mirrors, and adjustable pedals

being positioned based on the stored preset data.

2. The ignition switch must be in the RUN position, the transaxle must be in 'P' range, the vehicle speed must be 0

MPH, and the manual functions must not be in operation to recall stored presets.

3. Others

a. Play operation not recorded in the position switch will not be conducted and there will be no buzzer output.

b. If other data is received during preset recall operation, the most recent preset recall signal will take

precedence.

c. If engine is started during preset recall operation, halt preset recall operation, and resume it toward target

position 100ms after Ignition switch is returned to "RUN". However, if the START state lasts over 5 sec., it will
not resume even after returning to RUN.

d. If preset recall order is received during engine start, preset recall operation is inhibited.

e. If input from manual switch for seat and adjust pedal occurs during preset recall operation of seat and adjust

pedal, halt all their preset recall operations.

f. If an error occurs during manual operation of seat and adjust pedal, delete Memory.

4. Operation control

a. Prioritization of operations

Motor starting is delayed for 100ms respectively in case of auto control to prevent rush current from overlap
when motors are running, and it follows the following order.
Slide > recline > front height > rear height > adjust pedal

b. Memory preset recall is conducted in the following order, and delay time for each motor is as follows.

T1 : Manimum 0.1 sec.
Continuous cooperation TIMER value for each motor
Slide: 15 sec., recline: 30 sec., front height: 5 sec., rear height: 8 sec., adjust pedal: 10 sec.

c. Control when turning to the opposite direction

When motor has to be run in a reverse direction during Easy access function or preset recall operation, stop the
operation immediately, wait for 100ms and then try operation to the reverse direction.

d. If the difference between position and the current one is below specified value, motor will not run even though

preset recall data is received.
Slide, recline, front height, rear height : 6PULSE
Adjust pedal: 3LSB(about 0.06V)

e. Operation will stop upon reaching Motor's target point when conducting Easy access function or preset recall

operation.

EASY ACCESS FUNCTION OPERATION (SLIDE MOTOR ONLY)

1. Easy access function operation is allowed only when auto switch is on, and the operation will be halted if auto

switch changes from on to off.

2. If a key is removed and CAN BUS data transmitted from IPM changes from "on" to "off", the seat slide will move

50mm backward based on the IGN off point. If a key off position is farther back than 50mm against the IGN off
point, get-off gearing will not be conducted. If slide rear limit becomes off in the middle of backward operation,
retreat control will be halted.

3. The following conditions will be identified and processed by IMS, and if any one of the following conditions is met,

Easy access function operation will be prevented or halted.

a. When "P" position switch is not on.

b. When Vehicle Speed in CAN BUS data transmitted from cluster is "3km/h" or faster.

c. When seat and pedal is under manual switch operation.

d. When auto switch is off.

4. When control is halted in the middle of backward operation, the remaining operation will not be completed, and

when returning, it will return just as much as it retreated.

5. It will move to IGN off point in case of Get-on gearing by key in despite manual switch input during or after

backward operation.

6. After the key is removed, on the condition of SLEEP state, Easy access function operation will be conducted after

150ms if the key is inserted when auto switch is turned ON(OFF) from Off(ON).
