BLOWER CHECK
Perform the blower check in manual blower running state because it is difficult to check blower at automatic control. Blower is controlled from level 1 to
level 8 equally as in button operation and running logic. In turning on IG, blower relay is ON and voltage of 0.1 to 1.4 V is transferred from FATC
connector A4 terminal to base source of power TR according to FATC control (selectable from level 1 to level 8). At this time, voltage of blower motor's
both ends is determined according to collector voltage of FATC connector A5 terminal. If FATC is controlled in level 8, GND(0 V) is supplied for
FATC connector A18 terminal and high blower relay is driven.
