I-76
ENGINE <TURBO> - Control Svstem
COOLING FAN CONTROL
This sytem is similar to the one introduced on the
1994 Galant.
Two transistors inside the engine control module
control the radiator fan and the air conditioning con-
denser fan motor according to the engine coolant
temperature and the vehicle speed. When the air
conditioning switch and air conditioning pressure
switch are ON, the fan motor rotate at high speed
WI BK60AA
regardless of the engine coolant temperature and
vehicle speed.
l When the engine coolant temperature is faulty,
the fan motors (radiator and condenser) are
driven at high speed.
The engine control module also controls the
fan suitable to the various driving conditions
- cruising, accelerating and decelerating, etc.
