SYSTEM DESCRIPTION
NOTE:
If DTC P0217 is displayed with DTC U1000, first perform the trouble diagnosis for DTC U1000. Refer to
EC-79, "
DTC U1000 CAN COMMUNICATION LINE".
Cooling Fan Control
*: This signal is sent to ECM through CAN communication line.
The ECM controls the cooling fan corresponding to the vehicle speed, engine coolant temperature, refrigerant
pressure, and air conditioner ON signal. The control system has 3-step control [HIGH/LOW/OFF].
Cooling Fan Operation
Cooling Fan Relay Operation
The ECM controls cooling fan relays in the IPDM E/R through CAN communication line.
COMPONENT DESCRIPTION
Cooling Fan Motor
The cooling fan operates at each speed when the current flows in the cooling fan motor as follows.

CONSULT-II Reference Value in Data Monitor ModeEBS01KFL
Specification data are reference values.
On Board Diagnosis LogicEBS01KFM
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.
CAUTION:
When a malfunction is indicated, be sure to replace the coolant. Refer toCO-7, "
Changing Engine
Coolant". Also, replace the engine oil. Refer toLU-6, "Changing 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 toMA-16, "
Engine Coolant Mixture Ratio".
2. After refilling coolant, run engine to ensure that no water-flow noise is emitted.
Overall Function CheckEBS01KFN
Use this procedure to check the overall function of the cooling fan. During this check, a DTC might not be con-
firmed.
WARNING:
lNever remove a radiator cap and/or a reservoir tank cap when the engine is hot. Serious burns
could be caused by high pressure fluid escaping from the radiator and the reservoir tank.
lWrap a thick cloth around 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.

DTC P0217 ENGINE OVER TEMPERATURE
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 toEC-137,
"Diagnostic Procedure".
2. Confirm whether customer filled the coolant or not. If customer
filled the coolant, skip the following steps and go toEC-137,
"Diagnostic Procedure".
3. Turn ignition switch ON.
4. Perform “COOLING FAN” in “ACTIVE TEST” mode with CON-
SULT-II.
5. If the results are NG, go toEC-137, "
Diagnostic Procedure".
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 toEC-137,
"Diagnostic Procedure".
2. Confirm whether customer filled the coolant or not. If customer
filled the coolant, skip the following steps and go toEC-137,
"Diagnostic Procedure".
3. Perform IPDM E/R auto active test and check cooling fan motors operation, refer toPG-19, "
Auto Active
Te s t".
4. If NG, go toEC-137, "
