DTC DETECTION LOGIC
NOTE:
If DTC P1217 is displayed with DTC U1000 U1001, first perform the trouble diagnosis for DTC U1000
U1001. Refer to EC-128, "
DTC Logic".
If DTC P1217 is displayed with DTC U1010, first perform the trouble diagnosis for DTC U1010. Refer
to EC-129, "
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, be sure to replace the coolant. Refer to CO-11, "
Inspection". Also,
replace the engine oil. Refer to LU-7, "
Draining".
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-20, "
SAE Viscosity Number".
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-257, "
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-258, "
Diagnosis Procedure".
Component Function CheckINFOID:0000000001677295
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

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. Refer to EC-307, "
Diagnosis Procedure".
3.CHECK COOLING FAN HIGH SPEED OPERATION
With CONSULT-III
1. Touch “HIGH” on the CONSULT-III screen.
