< ECU DIAGNOSIS INFORMATION >
CLIMATE CONTROLLED SEAT CONTROL UNIT
Malfunction Malfunctioning condition
The temperature difference between the seatback ther-
mal electric unit and seat cushion thermal electric unit is
more than 30 °C When it detects for 4 seconds that the temperature difference between
the seatback thermal electric unit and seat cushion thermal electric unit
is more than 30 °, it stops the output to the thermal electric unit, activates
the climate controlled seat blower motor at the maximum position, and
sends the external airflow for 30 seconds
If the temperature difference is still more than 30 °C after 30 seconds
pass, it stops all output and enters the system OFF condition
When the temperature difference between seatback thermal electric unit and seat cushion thermal electric unit becomes less than 20 °C, the sys-
tem recovers automatically
If it detects that the temperature difference is more than 30 °C after the
automatic system recovery, it immediately stops all output and enters the
system OFF condition
NOTE:
When the switch operation is performed before entering the system OFF
condition, the fail-safe mode is reset.
The temperature of thermal electric unit is more than
11 0 °C in the HEAT mode (any thermal electric unit in the
seatback or seat cushion) When it detects for 4 seconds that the temperature of the thermal electric
unit is more than 110 °C, it stops the output to the thermal electric unit,
activates the climate controlled seat blower motor at the maximum posi-
tion, and sends the external airflow for 30 seconds
If the temperature does not become less than 105 °C after 30 seconds
pass, it stops all output and enters the system OFF condition
When the temperature of the thermal electric unit becomes less than 105 °C, the system recovers automatically
If it detects that the temperature of the thermal electric unit is more than
11 0 °C after the automatic system recovery, it immediately stops all out-
put and enters the system OFF condition
The temperature of the thermal electric unit is more than
45 °C in the COOL mode (any thermal electric unit in the
seatback or seat cushion) When it detects for 4 seconds that the temperature of the thermal electric
unit is more than 45 °C and less than 70 °C, it starts the temperature mon-
itoring of the thermal electric unit at 3 second intervals for increase in
temperature from the previous value
While monitoring, if it detects that the temperature continuously rises 2 °C
or more for 4 consecutive intervals or reaches 70 °C or more, it stops all
output and enters the system OFF condition
If it detects other results of monitoring, it continues activating in the se-
lected COOL mode
Thermal electric unit sensor open circuit
(in either the back and the cushion TEU) When it detects for 4 seconds that the thermal electric unit sensor is an
open circuit, it stops all output and enters the system OFF condition
Climate controlled seat blower motor system open circuit
(in either the back and the cushion blower) When it detects for 2 seconds that climate controlled seat blower motor
is an open circuit while the climate controlled seat is being activated, and
the battery status has been stable for the same 2 second period, it stops
output to the thermal electric unit
When it detects for 10 seconds that the climate controlled seat blower motor is an open circuit while the climate controlled seat is being activat-
ed, and the battery status has been stable for the same 10second period,
it stops all output and enters the system OFF condition
NOTE:
After detecting the climate seat blower motor system open circuit for 2
seconds, the system recovers automatically if the activation of the cli-
mate controlled seat blower motor is detected for 1 second or more.
Switch input out of the specified range
(either heat input or cool input) When it detects for 4 seconds that the rotary switch input is less than
30% of the vehicle battery voltage, it stops all output and enters the sys-
tem OFF condition
When the switch input returns to a value within the specified range, the
system recovers automatically
