AIR CONDITIONER CHECK
11 V is outputted from connector A17 terminal in turning on INSULATING and pressing air conditioner switch. However, although 11 V is outputted
from FATC connector A17 terminal, compressor clutch isn't driven. Wind of air conditioner is discharged if only compressor clutch works. Output signal
from air conditioner is inputted in engine computer through triple switch. Then, the engine computer considers several conditions and when output of air
conditioner is judged to be practical, it gives GND to signal terminal of air conditioner relay. Accordingly, relay of air conditioner is ON and compressor
clutch works. Triple switch checks pressure of refrigerant flowing through pipe and turns on/off switches in it according to standard. So, it controls that
output signal of air conditioner outputted from FATC is inputted into engine computer, and also speed of condenser fan according to pressure level. (For
high pressure, high-speed and for low pressure, low-speed.)
