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.

TROUBLE DIAGNOSISPFP:00004
Trouble Diagnosis IntroductionNHS00090
CAUTION:
Do not use electrical test equipment on any circuit related to the SRS unless instructed in this Ser-
vice Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or har-
ness connectors.
Do not repair, splice or modify the SRS wiring harness. If the harness is damaged, replace it with a
new one.
Keep ground portion clean.
DIAGNOSIS FUNCTION
The SRS self-diagnosis results can be read by using “AIR BAG” warning lamp and/or CONSULT-II.
The User mode is exclusively prepared for the customer (driver). This mode warns the driver of a system mal-
function through the operation of the “AIR BAG” warning lamp.
The Diagnosis mode allows the technician to locate and inspect the malfunctioning part.
The mode applications for the “AIR BAG” warning lamp and CONSULT-II are as follows:
HOW TO PERFORM TROUBLE DIAGNOSIS FOR QUICK AND ACCURATE REPAIR
A good understanding of the malfunction conditions can make troubleshooting faster and more accurate.
In general, each customer feels differently about a malfunction. It is important to fully understand the symp-
toms or conditions for a customer complaint.

NO >>INSPECTION END
4. CHECK DIAGNOSIS SENSOR UNIT
Connect CONSULT-II and touch “START”.
Is “AIR BAG” displayed on CONSULT-II?
YES or NO
YES >> GO TO 5.
NO >> Visually check the wiring harness connection of diagno-
sis sensor unit. If the harness connection check result is
OK, replace diagnosis sensor unit.
5. CHECK HARNESS CONNECTION
Is harness connection between warning lamp and diagnosis sensor unit OK?
