Power Seat Mod ule
The power seat module features driver s electable funct ions , and aut omat ic monit ori ng functi ons .
Driver Selectable Functions
Seat and ext erior mirror memory recall Immediat e s eat adjus t ment.
Seat and exterior mirror memory recall function
The memory recall functi on s ets t he driver's seat t o a s t ored pos it ion, and is acti v at ed when a swi tch pack memory
posi ti on butt on is pres sed. W hen memory recal l i s i ni ti ated, only 2 seat adjus tment mot ors wil l operat e at any one t ime to
li mit the overall current cons umpti on. To furt her minimize t he current l oad as the m otors energize, the i nit iati on of each of
t he 2 operati ng mot ors i s phas ed wi th a 10 mill is econd del ay. The cushi on s lide and backres t wil l move fi rs t , foll owed by
t he cus hion height .
As s oon as t he seat s wit ch pack memory pos it ion but ton is pres s ed, a mes sage i s t ran s mit ted by the power s eat modul e
on t he medium s peed CAN bus to the front door control modul es. The door cont rol modu les t hen act ivat e t he memory
recall pos it ions for t he exteri or mirrors. The i nst rument clus t er mess age cent er wil l di s pl ay memory recall mes s ages when
a memory recall i s acti vat ed.
The memory recall functi on operates wit h 2 s eparate modes; t he operat ion of each mod e is dependant on t he vehicle
s tat us when the seat memory posi ti on butt on is pres sed.
Memory recall operati ng modes:
One-t ouch mode Proport ional mode.
One-Touch Mode
W hen t he vehicle i s s tat ionary and a s wit ch pack memory pos it ion butt on i s pres sed, t he memory recall functi on wil l
operate in 'one-touch' mode. One t ouch mode all ows the seat and exterior mirrors t o immediatel y move t o t he request ed
s tored memory pos i ti on.
If a s eat adjus t ment or memory pos it ion but ton i s operat ed during memory recal l 'one -t ouch' mode, t he current memory
recall wi ll be cancell ed and t he seat (and ext eri or mirrors via t he medium s peed CAN bus) wi ll i mmediat el y s top movi ng.
The s eat will t hen commence movi ng in the di recti on that corresponds to the press ed s wi tch.

Memory recall is al s o immedi atel y cancelled if t he vehi cl e is driven from t he st ati o nary pos it ion before t he seat has
reached the reques t ed memory pos i ti on.
Proport ional Mode
If the vehicle is already in moti on when the swi tch pack memory posi ti on butt on is p ress ed, the memory recal l functi on wil l
operate in 'proport ional' mode. Proport ional mode recal ls the s eat (and ext erior mi r ror) pos it ion for the durat ion t hat the
memory s wit ch is held in the pres s ed s tat e. W hen t he memory pos i ti on but t on is relea s ed the memory recal l wil l
immediatel y s top, unles s the seat has already reached t he int ended memory pos it ion.
In order to reach t he int ended s t ored memory posi ti on whil e t he vehi cl e is moving, t he memory pos it ion but ton mus t not
be rel eased unt il all s eat, and exterior mi rror movement s are compl et e.
Immediate seat adjustment function
The immediate adjust ment functi on is act ivated when a s wit ch pack s eat posi ti on s wit ch (recl ine, s lide or height ) is
operated.
Pres s ing any of t he seat adjus t ment swi tches wil l init iat e t he corres pondi ng direct i on mot or to move t he seat i n t hat
direct ion, unti l t he s wit ch is releas ed. Onl y 2 s eat mot ors wi ll operate at any one ti me.
Automatic Monitoring Functions
The power seat module aut omati c monit ori ng functi ons are detai led as follows :
Stal l det ect ion mode Sleep mode
Batt ery moni tor mode.
Stall detection mode
A s eat mot or i s deemed t o have st all ed if t here i s no change i n t he input t hat i s re ceived from the corres ponding feedback

If a s tall condit ion i s det ected by t he power seat module then t he dri ve to that axi s i s cancell ed for t he remai nder of t hat
memory operati on (memory recal l), or unt il t he s wit ch is re-s elected (immediate s eat adjus t ment).
For al l seat mot or manual movements during an immedi at e s eat adjus tment funct ion, wh en a mot or is driven and a s t al l
occurs the power s eat modul e records and s t ores t he s tal l pos it ion (s oft s t op) t hat the s t all occurred. If movement occurs
beyond t he s tored s oft s top st all pos it ion, then t he s tal l pos it ion i s eras ed from t he power s eat modul e memory. Thi s wil l
always all ow movement past a previousl y recorded s t all posi ti on once movement has be en regi st ered beyond that pos it ion
(i.e. by press ing the s wi tch for longer t han 2 s econds ).
If the mot or movement has s t opped due t o a motor s tal l (s eat obs t ructi on for example ), once t he obst ruct ion i s cl eared
t hen that axi s may be act ivated again to move pas t t he new s oft s t op s tal l pos it ion by re-s elect ing t he appropriat e s wit ch
and pres s ing for longer t han 2 s econds . If t he s wit ch is not operat ed to move t he se at pas t the new soft s top pos it ion,
t hi s posi ti on wi ll remai n s tored in the power s eat modul e memory as t he full axis mo vement .
If motor movement has st opped due to los s of sens or feedback (s ens or or wiring failu re) then t hat axi s may be acti vat ed
agai n t o move pas t the st all posi ti on by re-s electi ng the appropriate s wit ch and pre s si ng for l onger t han 2 s econds. This
all ows cont rol of the motor t o be mai nt ained i f sens or feedback i s los t .
Upon re-s el ect ion of movement , if s ens or puls es are det ect ed t hen the mot or wil l con t inue t o be dri ven unt il t he s wit ch is
rel eas ed or another s tall condit ion i s det ected. If s ens or feedback is not det ect ed then t he mot or is only driven for 0.5
s econd and t hen s tops , unt il t he s wit ch is releas ed and then pres s ed again for longe r t han 2 s econds , when a furt her 0.5
s econd of acti vat ion i s permi tt ed and s o on. This i s known as 'i nch mode'.
If there is a fail ure wit h the medium speed CAN bus net work, the seat wi ll operate i n 'inch mode'.
• NOTE: For di agnos t ic purpos es, an i ndicat ion of medi um s peed CAN bus dis connecti on is apparent i f the s eat is operat ing
in 'inch mode' and eit her t he s eat cont rol module, CJB or door cont rol modules are n ot s hown connect ed t o t he medium
