P1217 ENGINE OVER TEMPERATURE

DTC Description

INFOID:0000000010703012

DTC DETECTION LOGIC

NOTE:
ECM controls cooling fan to the maximum speed when receives the signal abnormality of each sensor, CAN
and IPDM E/R,  and severed wire short circuit abnormality.
If the cooling fan or another component in the cooling system malfunctions, engine coolant temperature will
rise.

CAUTION:

When a malfunction is indicated, be sure to exchange the coolant and 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.

2.

After refilling coolant, run engine to ensure that no water-flow noise is emitted.

POSSIBLE CAUSE

• Harness or connectors (Cooling fan circuit is open or shorted.)
• IPDM E/R
• Cooling fan relay
• Cooling fan motor
• Cooling fan
• Radiator hose
• Radiator
• Radiator cap
• Water pump
• Thermostat
• Water control valve
• Amount of engine coolant

FAIL-SAFE

PERFORM DTC CONFIRMATION PROCEDURE

1.

CHECK DTC PRIORITY

If DTC P1217 is displayed with DTC UXXXX or P0607, first perform the trouble diagnosis for DTC UXXXX or
P0607.

Is applicable DTC detected?

YES

>> Perform diagnosis of applicable. Refer to 

ECM-93, "DTC Index"

.

NO

>> GO TO 2.

2.

PERFORM COMPONENT FUNCTION CHECK-1

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.

P1217 ENGINE OVER TEMPERATURE

Check the coolant level in the reservoir tank and radiator.
Allow engine to cool before checking coolant level.
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 coolant level in the reservoir tank and/or radiator below the
proper range?

YES

>> Proceed to 

ECM-322, "Diagnosis Procedure"

.

NO

>> GO TO 3.

3.

PERFORM COMPONENT FUNCTION CHECK-2

Confirm whether customer filled the coolant or not.

Did customer fill the coolant?

YES

>> Proceed to 

ECM-322, "Diagnosis Procedure"

.

NO

>> GO TO 4.

4.

PERFORM COMPONENT FUNCTION CHECK-3

With CONSULT

1.

Turn ignition switch ON.

2.

Select “FAN DUTY CONTROL” in “ACTIVE TEST” mode of “ENGINE” using CONSULT. Refer to 

ECM-65,

"CONSULT Function"

.

3.

Check that cooling fan speed varies according to the percentage.

Is the inspection result normal?

YES-1 >> To check malfunction symptom before repair: Refer to 

GI-41, "Intermittent Incident"

.

YES-2 >> Confirmation after repair: INSPECTION END
NO
