NOTE:
• If DTC P1217 is displayed with DTC UXXXX, first perform the tr ouble diagnosis for DTC UXXXX.
• If DTC P1217 is displayed with DT C P0607, first perform the trouble diagnosis for DTC P0607. Refer
to EC-404, "DTC Logic"
.
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 abnorma lly high temperature condition, a malfunction is
indicated.
CAUTION:
When a malfunction is in dicated, be sure to replace the coolant. Refer to CO-12, "Changing Engine
Coolant". Also, replace the engine oil. Refer to LU-10, "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-12, "FOR USA AND CANADA : Engine Cool-
ant 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-423, "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 >> Proceed to EC-424, "Diagnosis Procedure"
.
Component Function CheckINFOID:0000000009462353
1.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 ca p by turning it a quarter turn to allow built-up
pressure to escape. Then turn the cap all the way off.

Description".
2. Check that cooling fan operates.
Is the inspection result normal?
YES >> INSPECTION END
NO >> Proceed to EC-424, "Diagnosis Procedure"
.
