System DescriptionINFOID:0000000005532774
SYSTEM DESCRIPTION
NOTE:
•
If DTC P1217 is displayed with DTC UXXXX, first perform the trouble diagnosis for DTC UXXXX.
• If DTC P1217 is displayed with DTC P0607, first perform the trouble diagno sis for DTC P0607. Refer
to EC-895
.
Cooling Fan Control
*1: The ECM determines the start signal status by the signals of engine speed and battery voltage.
*2: 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 contro l system has 3-step control [HIGH/LOW/OFF].

Specification data are reference values.
On Board Diagnosis LogicINFOID:0000000005532776
If the cooling fan or another component in the cooli ng system malfunctions, engine coolant temperature will
rise. When the engine coolant temperature reaches an abnormally high temperature condition, a malfunction
is indicated.
This self-diagnosis has the on e trip detection logic.
CAUTION:
When a malfunction is in dicated, be sure to replace the coolant. Refer to CO-36, "
Changing Engine
Coolant". Also, replace the engine oil. Refer to LU-18, "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 to MA-15, "
Anti-freeze Coolant Mixture Ratio".
2. After refilling coolant, run engine to ensure that no water-flow noise is emitted.
Overall Function CheckINFOID:0000000005532777
Use this procedure to check the overall function of the cooling fan. During this check, a DTC might not be con-
firmed.

< SERVICE INFORMATION >[MR18DE]
DTC P1217 ENGINE OVER TEMPERATURE
Never remove the radiator cap when the engine is
hot. Serious burns could be caused by high pres-
sure fluid escaping from the reser voir tank or the radiator.
Wrap 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.
WITH CONSULT-III
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 EC-914,
"Diagnosis Procedure" or EC-914, "Diagnosis Procedure".
2. Confirm whether customer filled the coolant or not. If customer
filled the coolant, skip the following steps and go to EC-914,
"Diagnosis Procedure" or EC-914, "Diagnosis Procedure".
3. Turn ignition switch ON.
4. Perform “COOLING FAN” in “ACTIVE TEST” mode with CON- SULT-III.
5. If the results are NG, go to EC-914, "
Diagnosis Procedure" or EC-914, "Diagnosis Procedure".
WITH GST
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 EC-914,
"Diagnosis Procedure".
2. Confirm whether customer filled the coolant or not. If customer
filled the coolant, skip the following steps and go to EC-914,
"Diagnosis Procedure".
3. Perform IPDM/ER auto active te st and check cooling fan motor
operation. Refer to PG-20, "
Auto Active Test".
4. If NG, go to EC-914, "
Diagnosis Procedure".
