The cooling fans are mounted behind the radiator in the engine compartment. The electric cooling
fans increase the flow of air across the radiator fins and across the condenser on air conditioned
(A/C)-equipped vehicles.
This helps to speed cooling when the vehicle is at idle or moving at low speeds.
All models have two fans. The main fan is 320 mm (12. 6 inches) in diameter with seven blades to
aid the airflow through the radiator and the condenser. An electric motor attached to the radiator
support drives the fan.
The auxiliary fan is 320 mm (12.6 inches) in diameter.
A/C Off or Non-AC Model ▶
The cooling fans are actuated by the engine control module (ECM) using a low-speed
cooling fan relay, a high-speed cooling fan relay and a cooling fan motor relay.
The ECM will turn the cooling fans on at low speed when the coolant temperature reaches
95°C(203°F) and at high speed when the coolant temperature reaches 105°C(221°F).
The ECM will change the cooling fans from high peed to low speed at 100°C(212°F) and
will turn the cooling fans off at 90°C (194°F). -

A/C On ▶
The ECM will turn the cooling fans on at low speed when the A/C system is on. The ECM
will change to high speed when the high side A/C pressure reaches 1860 kPa (269.8 psi).
The cooling fans will return to low speed when the high side A/C pressure reaches 1378
kPa (199.8 psi). -

7) Engine Coolant Temperature Sensor
The Engine Coolant Temperature (ECT) sensor uses a temperature to control the signal voltage to
the Engine Control Module (ECM).
8) Coolant Temperature Gauge
The coolant temperature gauge controls the instrument panel temperature indicator. The coolant
temperature gauge is located with ECT sensor.

3. CAPACITY AND NAME OF FUSE AND RELAY IN ENGINE
COMPARTMENT
The label attached on each fuse
box indicates only major fuses and
relays. Therefore, there are more
fuses and relays than indicated.
For details about the connection
of fuses and relays, refer to the
power distribution circuit diagram

The relays in the ICM box cannot be replaced respectively; so if the any of the
components on the PCB are defective, they should be replaced as an assembly.

3) Operating Process by Power Supply of ICM Box
(1) Door lock relay
The power supplied through the No. F53 interior fuse on the left-hand of the engine compartment
is on standby on the No. 86 and 87 door lock relay terminals and No. 86 and 87 door unlock relay
terminals via the ICM No. 12 terminal. The STICS activates and/or controls the door lock relay
connected to the ICM No. 15 terminal using the STICS No. B3 terminal depending on the
operating conditions. The activated door lock relay supplies the No. 30 terminal with the B+
power, which is standby on the No. 87 terminal and supplies each door actuator with the B+
power.
The supplied power flows to the G201 ground connected to the ICM No. 14 terminal via the No.
30 and 87a door unlock relays for corresponding load.

(2) Door unlock relay
The supply power is on standby in the same way as the door lock relay, and the STICS activates
and/or controls the door unlock relay connected to the ICM No. 6 terminal using the STICS No.
A1 terminal depending on the operating conditions. The activated door unlock relay supplies the
No. 30 terminal with the B+ power, which is standby on the No. 87 terminal and supplies each
door actuator with the B+ power.
The supplied power flows to the G201 ground connected to the ICM No. 14 terminal via the No.
30 and 87a door lock relays for corresponding load.
