2) Power Transistor
The power transistor controls the fan speed. It controls the blower motor operating speed
without stages by changing the current value to the base of power transistor when receiving the
fan control signal from FATC.

(1) Inspection
If the power transistor defect code (DTC 6) is appeared, check as below.
▶
1. Turn the ignition switch to ON position.
2. Measure the voltage between terminals while changing the fan speed from stage 1 to stage
3. 6
The specified voltage value in each stage:
4. If the voltage is out of specified value, check the circuit for open. If the circuit is in normal
condition, replace the power transistor.
