FAN MOTOR OPERATION (1MZ±FE)
With the ignition SW turned on, the current through the ECU±IG fuse flows to the FAN NO.1 relay (Coil side), FAN NO.2 relay
(Coil side) and FAN NO.3 relay (Coil side). Furthermore, the current through the FAN NO.1 relay (Coil side) or the FAN NO.2
relay (Coil side) flows to TERMINAL 3 of the A/C single pressure SW to TERMINAL 2 to TERMINAL 2 of the water temp. SW
No.1 to TERMINAL 1 to GROUND, causing the FAN NO.1 relay to turn off and the FAN NO.2 relay to turn on.
1. LOW SPEED OPERATION
Only when the A/C system is activated or the water temp. SW No.2 is turned on, the A/C condenser fan motor and the
radiator fan motor rotates at low speed.
When the A/C system is activated, the current from ECU±IG fuse flows to the FAN NO.3 relay (Coil side) to TERMINAL 1 of
the diode (A/C) to TERMINAL 2 to TERMINAL (A)12 of the A/C amplifier (Manual A/C) or (B) 2 of the A/C control assembly
(Automatic A/C) causing the FAN NO.3 relay to turn on. As a result, the current through the CDS fuse flows to TERMINAL 2
of the A/C condenser fan motor to TERMINAL 1 to TERMINAL 3 of the FAN NO.2 relay to TERMINAL 5 to TERMINAL 5 of
the FAN NO.3 relay to TERMINAL 3 to TERMINAL 2 of the radiator fan motor to TERMINAL 1 to GROUND. As this flowing in
series for the motors, the motors rotate at low speed.
When the water temp. SW No.2 is turned on, the current from ECU±IG fuse flows to the FAN NO.3 relay (Coil side) to
TERMINAL 1 of the water temp. SW No.2 to GROUND, causing the FAN NO.3 relay to turn on. As a result, the current
through the CDS fuse flows the same route as above, rotating the motors at low speed.
2. HIGH SPEED OPERATION
Only when the A/C single pressure SW is turned off or the water temp. SW No.1 is turned off, the A/C condenser fan motor
and the radiator fan motor rotate at high speed.
When the A/C single pressure SW is turned off, the current from the RDI fuse flows to the FAN NO.1 relay (Point side) to
TERMINAL 2 of the radiator fan motor to TERMINAL 1 to GROUND. At the same time, the current from the CDS fuse flows
to TERMINAL 2 of the A/C condenser fan motor to TERMINAL 1 to TERMINAL 3 of the FAN NO.2 relay to TERMINAL 4 to
GROUND.
As the current flowing in parallel for the motors as above, the motors rotate at high speed.
FAN MOTOR OPERATION (5S±FE)
With the ignition SW turned on, the current through the ECU±IG fuse flows to the FAN NO.1 relay (Coil side), FAN NO.2 relay
(Coil side). furthermore, the current through the FAN NO.1 relay (Coil side) or the FAN NO.2 relay (Coil side) flows to
TERMINAL 3 of the A/C single pressure SW to TERMINAL 2 to TERMINAL 2 of the water temp. SW No.1 to TERMINAL 1 to
GROUND, causing the FAN NO.1 relay to turn off and the FAN NO.2 relay to turn on.
1. LOW SPEED OPERATION
When the ignition SW is turned on and the A/C system is activated, the A/C condenser fan motor and the radiator fan motor
rotates at low speed.
When the A/C system is activated, the current from MG CLT relay flows to the FAN NO.3 relay (Coil side) to GROUND,
causing the FAN NO.3 relay to turn on. As a result, the current through the CDS fuse flows to TERMINAL 2 of the A/C
condenser fan motor to TERMINAL 1 to TERMINAL 3 of the FAN NO.2 relay to TERMINAL 5 to TERMINAL 5 of the FAN
NO.3 relay to TERMINAL 3 to TERMINAL 2 of the radiator fan motor to TERMINAL 1 to GROUND. As this flowing in series
for the motors, the motors rotate at low speed.
2. HIGH SPEED OPERATION
Only when the A/C single pressure SW is turned off or the water temp. SW No.1 is turned off, the A/C condenser fan motor
and the radiator fan motor rotate at high speed.
When the A/C single pressure SW is turned off, the current from the RDI fuse flows to the FAN NO.1 relay (Point side) to
TERMINAL 2 of the radiator fan motor to TERMINAL 1 to GROUND. At the same time, the current from the CDS fuse flows
to TERMINAL 2 of the A/C condenser fan motor to TERMINAL 1 to TERMINAL 3 of the FAN NO.2 relay to TERMINAL 4 to
GROUND.
As the current flowing in parallel for the motors as above, the motors rotate at high speed.
