Have the injection pump
assembly serviced by an
authorised service repre-
sentative.
Disconnect and reconnect harness con-
nectors in the circuit. Then retest.
Trouble is not fixed.
Check ECM pin terminals for damage and
check the connection of ECM harness
connector. Reconnect ECM harness con-
nector and retest.

Description
SYSTEM DESCRIPTION
Sensor
Input signal to ECM
ECM function
Actuator
Engine coolant temperature
sensor
Engine coolant temperature
Cooling fan control
Cooling fan relay
Air conditioner switch
Air conditioner “ON” signal
The ECM controls the cooling fan corresponding to the vehicle speed, engine coolant temperature, air condi-
tioner ON signal.
On Board Diagnosis Logic
This diagnosis continuously monitors the engine coolant temperature.
If the cooling fan or another component in the cooling system malfunctions, engine coolant temperature will
rise.
When the engine coolant temperature reaches an abnormally high temperature condition, a malfunction is
indicated.

For more information, refer to “MAIN 12 CAUSES OF
OVERHEATING”, EC-425.
CAUTION:
When a malfunction is indicated, be sure to replace the coolant following the procedure in the LC
section, “Changing Engine Coolant”. Also, replace the engine oil.
1) Fill radiator with coolant up to specified level with a filling speed of 2 liters per minute. Be sure to
use coolant with the proper mixture ratio. Refer to MA section, “Engine Coolant Mixture Ratio”.
2) After refilling coolant, run engine to ensure that no water-flow noise is emitted.

Overall Function Check
Use this procedure to check the overall function of the cooling fan.
During this check, a DTC might not be confirmed.
WARNING:
Never remove the radiator cap when the engine is hot. Serious
burns could be caused by high pressure fluid escaping from
the radiator.
Wrap a thick cloth around the cap. Carefully remove the cap
by turning it a quarter turn to allow built-up pressure to
escape. Then turn the cap all the way off.
WITH CONSULT-II
1) Check the coolant level in the reservoir tank and radiator.
Allow engine to cool before checking coolant level.
If the coolant level in the reservoir tank and/or radiator is below
the proper range, skip the following steps and go to “Diagnos-
tic Procedure”, EC-421.
2) Confirm whether customer filled the coolant or not. If customer
filled the coolant, skip the following steps and go to “Diagnos-
tic Procedure”, EC-421.
3) Turn ignition switch “ON”.
4) Perform “COOLING FAN” in “ACTIVE TEST” mode with CON-
SULT-II and make sure that cooling fans operate.
If NG, go to “Diagnostic Procedure”, EC-421.
WITHOUT CONSULT-II
1) Check the coolant level in the reservoir tank and radiator.
Allow engine to cool before checking coolant level.
If the coolant level in the reservoir tank and/or radiator is below
the proper range, skip the following steps and go to “Diagnos-
tic Procedure”, EC-421.
2) Confirm whether customer filled the coolant or not. If customer
filled the coolant, skip the following steps and go to “Diagnos-
tic Procedure”, EC-421.
3) Start engine.
Be careful not to overheat engine.
4) Set temperature control lever to full cold position.
5) Turn air conditioner switch “ON”.
6) Turn blower fan switch “ON”.
7) Run engine at idle for a few minutes with air conditioner oper-
ating.
Be careful not to overheat engine.
8) Make sure that cooling fans operate at low speed.
9) Turn ignition switch “OFF”.
10) Turn air conditioner switch and blower fan switch “OFF”.
11) Disconnect engine coolant temperature sensor harness con-
nector.
12) Connect 150
Ω
resistor to engine coolant temperature sensor
harness connector.
13) Start engine and make sure that cooling fans operate at higher
speed than low speed.
Be careful not to overheat engine.
14) If NG, go to “Diagnostic Procedure”, EC-421.
