1. Manual control(CAN Data signal from DDM to PSM) with direction switches Seat operation is carried out in PSM according to user handling of manual switches when the following conditions are satisfied. Manual Switches ON (Slide Front/Rear, Recline Front/Rear, Front Height Up/Down, Rear Height Up/Down, Head Rest Up/Down, Cushion Extension Front/Rear) PSM is different from a value of maximum continuous time for each motors Slide: 20s +/- 2s Recline: 35s +/- 3s Front Height: 10s +/- 1s Rear Height: 20s +/- 1.5s Head Rest: 10s +/- 1s Cushion Extension: 15s +/- 1s Manual(CAN Data signal from DDM to PSM) has priority although self-diagnosis actuator operation order is received (actuator operation ignorance)
2. Playback With Position Switches PSM controls a seat position according to memorized position by memory function, and PSM has 2 memories for position that is selected by CAN signal of P Back P1 CMD and P Back P2 CMD command. The playback prohibition (start) conditions The playback stop conditions Exception) Playback is done without halt at P position=Not P, while playback in B+ after IGN SW = OFF --> KEY IN The playback halt play conditions If IGN SW PSM state changes IGN SW PSM=IGN --> ST during playback, playback is temporarily stopped, but if it returns to IGN SW PSM=IGN state, playback is done to a memorized position after 100ms But if IGN SW PSM=ST state is more than 30 seconds, playback is not done even though IGN SW PSM state returns to IGN SW PSM = IGN Playback and Buzzer output If CAN signal P Back P1 CMD or P Back P2 CMD receive ON, Seat moves to a memorized position Buzzer output is done even though seat is error state But, if seat position was not memorized, buzzer output is not done The notice about playback No memorized playback CAN signals are not done playback If other playback CAN signals are received during playback, the last CAN signal have a priority playback If the same playback CAN signal is repeatedly received, a position is never moved If the difference between memorized position and present position are less than the regulation pulse(**1), motor is not move Slide and Recline are less than 12Edge(6Pulse), Fr Hg, Rr Hgt, Cushion Extension and head rest are less than 8Edge(4Pulse).
3. Memory with position switches PSM memorizes position once if one of Mem P1 CMD or Mem P2 CMD command is changed to ON. Memory enable CAN signal Mem ENB = Enable Memory operation If CAN signal Mem P1 CMD=P1 or Mem P2 CMD=P2 is received, PSM memorizes a present seat position The notice about memory Memory must not be clear even though battery was removed. Easy Access operation The Easy Access operation function controls seat position according to IGN SW PSM = Key Off exception f-->Key Off or Key Off-->Key Off exception If IGN SW PSM = Key Off exception is changed to IGN SW PSM = Key Off, seat automatically moves to getting out position, and If IGN SW PSM = Key Off is changed to IGN SW PSM = Key Off exception, seat automatically moves to getting in position Easy Entry operation conditions IGN SW PSM=Key Off --> Key Off exception Easy Exit operation conditions & Easy Exit operation position memory conditions IGN SW PSM=Key Off exception --> Key Off Easy Access operation a stop condition Easy Entry operation halt play conditions In case of button starting and IGN SW PSM ST --> IGN, Easy Entry operation continuously operates If IGN SW PSM state changes IGN SW PSM=IGN --> ST during Easy Entry operation, Easy Entry operation is temporarily stopped, but if it return to IGN SW PSM=IGN state, Easy Entry operation is done to memorized position after 100ms But if IGN SW PSM=ST state is more than 30 seconds, Easy Entry operation is not done even though IGN SW PSM state return to IGN SW PSM=IGN In case of BUTTON Start action during Play Back Slide Motor will continue to playback and Slide Motor exceptions move to memorized position Relations between Easy Access operation and Playback Playback during Easy Entry operation In case of Playback during Easy Entry operation, Easy Entry operation is stopped and start Playback Easy Exit operation during playback In case of Easy Exit operation during Playback, Only slide motor is Easy Exit operation and slide motor exceptions move to memorized position Easy Entry Position Renewal If CAN signal P Back1 or P Back2 is received, Easy Entry Position Renewal If CAN signal PBack1 or P Back2) is received at IGN SW=Key Off, Easy Entry Position (Slide) to Memory1(or Memory2) as a location for renewal Without taking into account any conditions At IGN SW=Key In later In case of Manual Action Easy Entry Position to renew it Of PlayBack, Easy Access operation Of Play Back In Key In State, In case of receiving command Key In --> Key Off Slide Play Easy Entry Operation, Slide Motor exceptions move to memorized position Of Key Off PlayBack, When receive Key Off --> Key In --> Key Off command Slide Motor play Easy Access Operation or Stop operation, Slide Motor exceptions move to memorized position However, the Easy Access operation is operating Slide Motor following conditions, consider the action In Easy Access Operation range, when Key Off --> key in --> Key Off Actions range Easy Access operation only action. (Actions range Easy Access operation: Easy Entry Position + 50mm >= Present Position >= Easy Entry Position - 50mm) Out of Easy access operation range, when Key Off --> key in --> Key Off (Slide motor stop) Slide Motor stop, Slide Motor exceptions move to memorized position Actions range Easy Access operation: Present position <= Easy Entry Position - 50mm (In case of Slide Motor Rear direction position than easy access operation range) Arbitration Control Power seat function is carried out according to the following priority table, If power seat requirement happen same time. * 1: Only slide motor *-: non-existence condition Notice (Manual, Playback, Easy Access operation) Judgment the order of priority Automatic control delays a moving time for each other 100ms to prevent a inrush current overlapping when motor is running. Control when motor running direction is a reversed turn When motor want to move a reverse turn, it is immediately stopped and move to a reverse turn after 100ms

The Tilt & Telescope operation function in SCM contains of the following function.

1. Manual control with direction switches (Tilt Up/Down, Telescope Forward/Backward).
2. Playback with position switches (P1 and P2 switches).
3. Memory with position switches (P1 and P2 switches).
4. Easy Access operation control according to the IGN SW SCM = Key Off-->Key Off exception or IGN SW SCM=Key Off exception --> Key Off
5. Easy Entry Position Renewal
6. Arbitration control
7. Detecting error
8. Notice (Manual, Memory Playback, Easy Access operation)

Mechanical Limit Setting By Normal Operation (TILT)

1. The initial SOFT LIMIT is set 8000H (It can't work as SOFT LIMIT)
2. The mechanical LIMIT is renewal by MANUAL SW of TILT to up or down.
3. If 4 pulse is not occurred in 1 sec. in running to up or down direction at the first time, the mechanical LIMIT is set.
4. In case of the difference of both limit pulse is over 100pulse, SOFT LIMIT is set at ±12PULSE from Mechanical limit.

Mechanical Limit Setting By Normal Operation (TELE)

1. The initial SOFT LIMIT is set 8000H (It can't work as SOFT LIMIT)
2. The mechanical LIMIT is renewal by MANUAL SW of TELE to push direction or pull direction.
3. If 4 pulse is not occurred in 1 sec. in running to push direction or pull direction at the first time, the mechanical LIMIT is set.
4. In case of the difference of both limit pulse is over 120pulse, SOFT LIMIT is set at ±12PULSE from Mechanical limit.

Easy Access Operation

The Easy Access operation function controls Tilt & Telescope position according to IGN SW SCM = Key Off exception-->Key Off or Key Off-->Key Off exception.

If IGN SW SCM = Key Off exception is changed to IGN SW SCM = Key Off, Tilt and Telescope move to the maximum up SOFT LIMIT and PUSH SOFT LIMIT direction.

And if IGN SW SCM = Key Off is changed to IGN SW SCM = Key Off exception, Tilt and Telescope move to a position that IGN SW SCM = Key Off exception --> Key Off was occurred
