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.

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.

At the time of work, please turn OFF a switch, and carry it out after checking that the thermal elec-
tric device has got cold.
Power is at all times supplied
through 15A fuse [No. 41 located in the fuse fusible link and relay unit]
to climate controlled seat relay terminals 5.
through 15A fuse [No. 42 located in the fuse fusible link and relay unit]
to climate controlled seat relay terminals 7.
When the ignition switch turned to ON or START position,
Power is supplied
through 10A fuse [No. 12, located in the fuse block (J/B)]
to climate controlled seat relay terminal 2.
Then ground is supplied
to climate controlled seat relay terminal 1,
through body grounds E22 and E43.
Then climate controlled seat relay is energized.
When climate controlled seat relay is turned to ON,
Power is supplied,
through climate controlled seat relay terminal 3,
to climate controlled seat control unit (passenger side) terminal 2 and 4.
through climate controlled seat relay terminal 6,
to climate controlled seat control unit (driver side) terminal 2 and 4.
When climate controlled switch select HEAT, ground is supplied
through climate controlled seat switch terminal 1 and 3,
to climate controlled seat control unit terminal 10.
Then, the climate controlled seat control unit receives climate controlled seat switch HEAT signal.
When climate controlled seat switch select COOL, ground is supplied
through climate controlled seat switch terminal 1 and 2,
to climate controlled seat control unit terminal 20,
Then, the climate controlled seat control unit receives climate controlled switch COOL signal.
When blower motor rotates, signal is transmitted
to climate controlled seat control unit terminal 18,
through climate controlled seat blower motor terminal 1.
This is climate controlled seat blower motor tachometer signal.
When climate controlled seat control unit receives climate controlled seat switch signal and tachometer signal,
Power is supplied
to climate controlled seat blower motor terminal 4,
through climate controlled seat control unit terminal 17.
This is blower motor revolution control signal.
When blower motor receivers blower motor revolution control signal,
Power is supplied
through climate controlled seat control unit terminal 14,
to climate controlled seat blower motor terminal 2.
When number of rotations correspond signal,
Ground is supplied
to climate controlled seat blower motor terminal 3,
through climate controlled seat control unit terminal 7,
through climate controlled seat control unit terminal 3,
through body grounds B5, B40 and B131.
Then motor revolution is controlled.
When the ignition switch turned to ON or START position,
Power is supplied
