Heater Control

Second Row Seat Heaters

The second row seat heater control unit performs control to each set temperature (Low/Mid/High) based on the value of the built-in thermistor of the second row seat cushion heater.

Automatic Operation

Based on the outside air temperature, A/C target temperature, and other factors, the climate control unit calculates the optimal second row seat heater setting. The climate control unit sends this setting request to the second row seat heater control unit via B-CAN.

When operating in auto mode, the second row seat heater control unit will operate per the B-CAN setting request from the climate control unit.
