System Diagram

INFOID:0000000003820817

System Description

INFOID:0000000003820814

• The heated seat system is controlled by the ventilation seat control unit.
• The heated seat system consists of the heated seat switch, the heater unit and the ventilation seat control

unit.

• The function of the heated seat system is to warm the seat surface.
• The heated seat system has a LO and HI mode that can be switched back and forth. The LO mode warms

the seat surface slowly and the HI mode warms it quickly.
The indicator on the heated seat switch indicates the operating status of each mode. 
NOTE:
• The memory function is adopted for the front seat. When the ignition switch turns ON again after turning

OFF, while the heated seat is being operated, the heated seat system restarts at the same warmness as
the previous operation. 

• For the rear seat, when the ignition switch turns ON again after turning OFF, while the heated seat is being

operated, the heated seat system does not restart and stays in the OFF position.

• While the heated seat system is being operated, the ventilation seat system becomes invalid.

LO MODE OPERATION

• When the LO button of the heated seat switch is pressed, while the ignition switch is ON, the ventilation seat

control unit supplies the seat heater with the LO mode power supply and simultaneously illuminates the LO
mode indicator in the heated seat switch.

• The seat heater warms the seat cushion and seatback to a low temperature by the LO mode power supply.
• When the LO button is pressed again, while the heated seat switch is in the LO mode position, the indicator

and the heated seat switch turn OFF. 

HI MODE OPERATION

• When the HI button of the heated seat switch is pressed, while the ignition switch is ON, the Ventilation and

Heated seat control unit supplies the seat heater with the HI mode power supply and simultaneously illumi-
nates the HI mode indicator in the heated seat switch.

• The seat heater warms the seat cushion and seatback to a high temperature by the HI mode power supply.
• When the HI button is pressed again, while the heated seat switch is in the HI mode position, the indicator

and the heated seat switch turn OFF. 

FAIL-SAFE

The fail-safe function is adopted for the ventilation seat control unit. Refer to 

SE-59, "FRONT SEAT : Fail-

safe"
