CLIMATE CONTROLLED SEAT

PFP:870U6

System Description

AIS002BX

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

temperature.

●

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 temper-
ature switch or the dial.

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. 71, and 72, located in the fuse fusible link and relay unit] 

●

to climate controlled seat relay terminals 5 and 7.

When climate controlled switch select “COOL”, ground is supply

●

through climate controlled seat switch terminal J16,

●

to climate controlled seat control unit terminal J16,

●

through climate controlled seat switch terminal JCA, 

●

through body grounds B17 and B57.

●

through climate controlled seat control unit terminal J13,

 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 J10,

●

to climate controlled seat blower motor terminal J10.

When number of rotations correspond signal,
Ground is supplied

●

to climate controlled seat blower motor terminal J3,

●

through climate controlled seat control unit terminal J3,

●

through climate controlled seat control unit terminal JC,

●

through body grounds B217 and B256.

Then motor revolution is controlled.
When the ignition switch turned to ON or START position,
Power is supplied

●

to climate controlled seat cushion thermal electric device terminal J18, 

●

through climate controlled seat control unit terminal J18.

Then ground is supplied

●

to climate controlled seat control unit terminal J17,

●

through climate controlled seat cushion thermal electric device terminal J17, 

Then the climate controlled seat control unit recognizes seat cushion thermal electric device sensor signal.
When climate controlled control unit recognizes climate controlled switch “HEAT” signal and, seat cushion
thermal electric device sensor signal,
Power is supplied

●

to climate controlled seat cushion thermal electric device terminal J1, 

●

through climate controlled seat control unit terminal J1,

●

through body grounds B217 and B256.

When climate controlled control unit recognizes climate controlled switch “COOL” signal and, climate con-
trolled seat cushion thermal electric device sensor signal,
Power is supplied

●

to climate controlled seat cushion thermal electric device terminal J2,
