DTC DETECTION LOGIC

NOTE:
• If DTC P1217 is displayed with DTC U1000 or U1001, first perform the trouble diagnosis for DTC

U1000, U1001. Refer to 

EC-135, "DTC Logic"

.

• If DTC P1217 is displayed with DTC P0607, first perform the trouble diagnosis for DTC P0607. Refer

to 

EC-242, "DTC Logic"

.

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, always replace the coolant. Refer to 

CO-8, "Draining"

. Also, replace

the engine oil. Refer to 

LU-8, "Draining"

.

1.

Fill radiator with coolant up to specified level with a filling speed of 2 liters per minute. Always use
coolant with the proper mixture ratio. Refer to 

MA-12, "Engine Coolant Mixture Ratio"

.

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-250, "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 

EC-251, "Diagnosis Procedure"

.

Component Function Check

INFOID:0000000003856719

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.

Trouble diagnosis name

DTC detecting condition

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 relays)
• Cooling fan motor
• Radiator  hose
• Radiator
• Radiator  cap

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 

EC-251, "Diagnosis Procedure"

.

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 

EC-251, "Diagnosis Procedure"

.

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.

Check that cooling fan motors-1 and -2 operate at each speed (LOW/MID/HI).

Without CONSULT-III

Perform IPDM E/R auto active test and check cooling fan motors operation, refer to 

PCS-11, "Diagnosis

Description"

.

Is the inspection result normal?

YES

>> INSPECTION END

NO

>> Go to 

EC-251, "Diagnosis Procedure"

Diagnosis Procedure

INFOID:0000000003856720

1.

CHECK COOLING FAN OPERATION

With CONSULT-III

1.

Turn ignition switch ON.

2.

Perform “COOLING FAN” in “ACTIVE TEST” mode with CONSULT-III.

3.

Check that cooling fans-1 and -2 operate at each speed (LOW/MID/HI).

Without CONSULT-III

1.

Perform IPDM E/R auto active test and check cooling fan motors operation, refer to 

PCS-11, "Diagnosis

Description"

.

2.

Check that cooling fans-1 and -2 operate at each speed (Low/Middle/High).

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Go to 

EC-324, "Diagnosis Procedure"

.

2.

CHECK COOLING SYSTEM FOR LEAK-I

Check cooling system for leak. Refer to 

CO-8, "Inspection"

.

Is leakage detected?

YES

>> GO TO 3.

NO

>> GO TO 4.

3.

CHECK COOLING SYSTEM FOR LEAK-II

Check the following for leak.
• Hose
• Radiator
• Water pump
