Component Parts and Harness Connector LocationNIS00272
System DescriptionNIS00273
The rear power seat (LH / RH) retreats when the auto return cancel switch is turned on and each door is
opened.
When the rear power seat switch turned on, or auto return cancel switch is canceled, an auto return is discon-
tinued.
Power is all time supplied

through 50A fusible link [letter F, located in the fuse block (J/B)],

to rear LH seat control unit, rear RH seat control unit terminal 1.
REAR POWER SEAT LH AND RH OPERATION
When rear power seat switch is forward, ground is supplied

to rear seat control unit terminal 10,

through rear power seat switch terminal 2,

through rear power seat switch terminal 3,

through body grounds B5, B40, B131.
When rear seat control unit receives power seat switch forward signal, power is supplied

through rear seat control unit terminal 2,

to rear seat sliding motor terminal 3.

CLIMATE CONTROLLED SEAT
Revision: 2007 April2007 M35/M45
CLIMATE CONTROLLED SEATPFP:870U6
Component Parts and Harness Connector LocationNIS0027H
System DescriptionNIS0027I
The climate controlled seat system is controlled by climate controlled seat control unit.
Heating and cooling are possible for a thermal electric device (heat conversion machine).
NOTE:

The climate controlled seat system is downed when the temperature sensor set as the seat cushion and
the seat back's thermal electric device machine detects 20 °C (68 °F)or more of mutual differences of tem-
perature.

In this case, by turning off ignition switch, system down is canceled and it can be reused by turning on
ignition switch again.

The climate controlled seat blower keep low speed for approximately 60 seconds after turning the climate
controlled seat switch.
CAUTION:

The thermal electric device has the character in which, as for an opposite side. one side becomes
high temperature at the time of low temperature.
