DTC Logic

INFOID:0000000010309143

DTC DETECTION LOGIC

If the cooling fan or other 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. Also, replace the 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.

DTC CONFIRMATION PROCEDURE

1.

PERFORM COMPONENT FUNCTION CHECK

Perform component function check. Refer to 

EC9-216, "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 

EC9-217, "Diagnosis Procedure"

.

Component Function Check

INFOID:0000000010309144

1.

PERFORM COMPONENT FUNCTION CHECK-1

WARNING:

Never remove the reservoir tank cap when the engine is hot. Serious burns could be caused by high
pressure 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.
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

>> Proceed to 

EC9-217, "Diagnosis Procedure"

.

NO

>> GO TO 2.

2.

PERFORM COMPONENT FUNCTION CHECK-2

DTC No.
