Purpose
The power MOS FET controls the blower motor rotation speed.
Function
The power MOS FET controls the supply voltage to the blower motor based on the gate voltage sent from the climate control unit, and adjusts the fan rotation speed (airflow volume).
Construction
The power MOS FET is installed to the A/C unit.
A transistor-type power MOS FET has been adopted and it is equipped with three electrodes, a source, a gate, and a drain.
Operation
The resistance between terminals B and A (between drain and source) changes according to the voltage (gate voltage) applied to terminal E (gate).
When the gate voltage increases, the resistance between terminals B and A decreases, allowing the current to flow easily. Therefore, the blower motor rotation speed increases.
When the gate voltage decreases, the resistance between terminals B and A increases, making current flow difficult. Therefore, the blower motor rotation speed decreases.
Fail-safe
Function not equipped.

Antilock Brake System (ABS)
The ABS control unit continuously monitors the speed of each wheel. If one wheel
is about to lock up, the ABS responds by automatically releasing and reapplying
that wheel's brake.
The driver will feel a slight vibration in the brake pedal and may hear a chattering
noise from the brake sy ...
Ambient Temperature Sensor [Full Auto Air Conditioner]
Purpose
The ambient temperature sensor detects the ambient temperature.
Function
The ambient temperature sensor converts the detected temperature to an electric
signal.
Construction
A thermistor-type ambient temperature sensor has been adopted.
The ambient ...
