DTC DETECTION LOGIC
NOTE:
• If DTC P1217 is displayed with DTC U1001, first perform the trouble diagnosis for DTC U1001. Refer
.
• If DTC P1217 is displayed with DTC U1010, first perform the trouble diagnosis for DTC U1010. Refer
.
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 to
. Also,
replace the engine oil. Refer to
.
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
2.
After refilling coolant, run engine to ensure that no water-flow noise is emitted.
DTC CONFIRMATION PROCEDURE
1.
PERFORM COMPONENT FUNCTION CHECK
Perform component function check. Refer to
EC-870, "Component Function Check"
.
NOTE:
Use component function check to check the overall function of the cooling fan. During this check, a DTC might
not be confirmed.
Is the inspection result normal?
YES
>> INSPECTION END
NO
>> Go to
Component Function Check
INFOID:0000000001089450
1.
PERFORM COMPONENT FUNCTION CHECK-I
WARNING:
Never remove the radiator cap when the engine is hot. Serious burns could be caused by high pres-
sure fluid escaping from 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.
DTC No.

Possible cause
P1217
Engine over tempera-
ture (Overheat)
• Cooling fan does not operate properly (Over-
heat).
• Cooling fan system does not operate proper-
ly (Overheat).
• Engine coolant was not added to the system
using the proper filling method.
• Engine coolant is not within the specified
range.
• Harness or connectors
(The cooling fan circuit is open or short-
ed.)
• IPDM E/R (Cooling fan relay-1)
• Cooling fan relay -3
• Cooling fan motor
• Radiator hose
• Radiator
• Radiator cap
• Reservoir tank
• Water pump
• Thermostat
• Water control valve

P1217 ENGINE OVER TEMPERATURE
Check the coolant level in the reservoir tank and radiator.
Allow engine to cool before checking coolant level.
Is the coolant level in the reservoir tank and/or radiator below the
proper range?
YES
>> Go to
NO
>> GO TO 2.
2.
PERFORM COMPONENT FUNCTION CHECK-II
Confirm whether customer filled the coolant or not.
Did customer fill the coolant?
YES
>> Go to
NO
>> GO TO 3.
3.
PERFORM COMPONENT FUNCTION CHECK-III
With CONSULT-III
1.
Turn ignition switch ON.
2.
Perform “COOLING FAN” in “ACTIVE TEST” mode with CONSULT-III.
3.
Make sure that cooling fan motor operate at each speed (LOW/HI).
Without CONSULT-III
Perform IPDM E/R auto active test and check cooling fan motors operation, refer to
.
Is the inspection result normal?
YES
>> INSPECTION END
NO

Diagnosis Procedure
INFOID:0000000001089451
1.
INSPECTION START
Do you have CONSULT-II?
Yes or No
Yes
>> GO TO 2.
No
>> GO TO 4.
2.
CHECK COOLING FAN LOW SPEED OPERATION
With CONSULT-III
1.
Turn ignition switch ON.
2.
Perform “COOLING FAN” in “ACTIVE TEST” mode with CONSULT-III and touch “LOW” on the CON-
SULT-III screen.
3.
Make sure that cooling fan operates at low speed.
Is the inspection result normal?
YES
>> GO TO 3.
NO
>> Check cooling fan control circuit.
3.
CHECK COOLING FAN HIGH SPEED OPERATION
With CONSULT-III
1.
Touch “HIGH” on the CONSULT-III screen.
2.
Make sure that cooling fan operates at higher speed than low speed.
Is the inspection result normal?
YES
>> GO TO 6.
NO
>> Check cooling fan control circuit.
4.
CHECK COOLING FAN LOW SPEED OPERATION
