GENERAL INFORMATION

M1141000102333

The cooling system is designed to keep every part of 
the engine at appropriate temperature in whatever 
condition the engine may be operated. The cooling 
method is of the water-cooled, pressure forced circu-
lation type in which the water pump pressurizes cool-
ant and circulates it throughout the engine. If the 
coolant temperature exceeds the prescribed temper-
ature, the thermostat opens to circulate the coolant 

through the radiator as well so that the heat 
absorbed by the coolant may be radiated into the air. 
The water pump is of the centrifugal impeller type 
and is driven by the drive belt from the crankshaft. 
The radiator is the corrugated fin, cross flow type.

Trouble symptom

Inspection procedure No. Reference page

Radiator fan and condenser fan do not operate

P.14-5

SYMPTOM PROCEDURES

Inspection Procedure 1: Radiator Fan and Condenser Fan do not Operate 

OPERATION

• Based on the signal from the engine coolant tem-

perature sensor and the signal from the second-
ary pulley speed sensor signal (vehicle speed 
signal) from the CVT-ECU, and the A/C switch 
signal from the A/C-ECU, the engine-ECU sends 
the radiator fan and condenser fan control signal 
to the ETACS-ECU via CAN bus line.

• Based on the radiator fan and condenser fan con-

trol signal from the engine-ECU, the ETACS-ECU 
turns ON/OFF the radiator fan relay, condenser 
fan relay, and the fan control relay to control the 
rotation of the radiator fan motor and condenser 
fan motor.

TECHNICAL DESCRIPTION

• If the radiator fan and condenser fan do not oper-

ate, the radiator fan motor, the condenser fan 
motor, the radiator fan relay, the condenser fan 
relay, the fan control relay, the ETACS-ECU may 
be defective.

• The CAN bus line, ETACS-ECU, CVT system, 

A/C system, or MPI system may also be defec-
tive.

PROBABLE CAUSES

• Malfunction of CAN bus system.

• Damaged harness or connector.

• Malfunction of the MPI system.

• Malfunction of the CVT system. 

• Malfunction of the A/C system.

• Malfunction of fusible link SBF3.
