NOTE:
Check “A/F ALPHA-B1”, “A/F ALPHA-B2” for approximately 1 minute because they may fluctuate. It is NG
if the indication is out of the SP value even a little.
Is the measurement value within the SP value?
YES >> GO TO 17.
NO-1 >> Less than the SP value: GO TO 2.
NO-2 >> More than the SP value: GO TO 3.
2.CHECK “B/FUEL SCHDL”
Select “B/FUEL SCHDL” in “SPEC” of “DATA MONITOR” mode, and check that the indication is within the SP
value.
Is the measurement value within the SP value?
YES >> GO TO 4.
NO >> More than the SP value: GO TO 19.
3.CHECK “B/FUEL SCHDL”
Select “B/FUEL SCHDL” in “SPEC” of “DATA MONITOR” mode, and check that the indication is within the SP
value.
Is the measurement value within the SP value?
YES >> GO TO 6.
NO-1 >> More than the SP value: GO TO 6.
NO-2 >> Less than the SP value: GO TO 25.
4.CHECK “A/F ALPHA-B1”, “A/F ALPHA-B2”
1. Stop the engine.
2. Disconnect PCV hose, and then plug it.
3. Start engine.
4. Select “A/F ALPHA-B1”, “A/F ALPHA-B2” in “SPEC” of “DATA MONITOR” mode, and check that the each
indication is within the SP value.
Is the measurement value within the SP value?
YES >> GO TO 5.
NO >> GO TO 6.
5.CHANGE ENGINE OIL
1. Stop the engine.
2. Change engine oil.
NOTE:
This symptom may occur when a large amount of gasoline is mixed with engine oil because of driving
conditions (such as when engine oil temperature does not rise enough since a journey distance is too
short during winter). The symptom will not be detected after changing engine oil or changing driving con-
ditions.
>> INSPECTION END
6.CHECK FUEL PRESSURE
Check fuel pressure. (Refer to EC-411, "
Inspection".)
Is the inspection result normal?
YES >> GO TO 9.
NO-1 >> Fuel pressure is too high: Replace “fuel filter and fuel pump assembly” and then. GO TO 8.
NO-2 >> Fuel pressure is too low: GO TO 7.
7.DETECT MALFUNCTIONING PART
Check fuel hoses and fuel tubes for clogging.
Is the inspection result normal?
YES >> Replace “fuel filter and fuel pump assembly” and then GO TO 8.
NO >> Repair or replace malfunctioning part and then GO TO 8.
8.CHECK “A/F ALPHA-B1”, “A/F ALPHA-B2”

DTC CONFIRMATION PROCEDURE
1.PRECONDITIONING
If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait at
least 10 seconds before conducting the next test.
TESTING CONDITION:
Before performing the following procedure, confirm that battery voltage is between 10 V and 16 V at
idle.
>> GO TO 2.
2.PERFORM DTC CONFIRMATION PROCEDURE-I
With CONSULT-III
1. Turn ignition switch ON and select “DATA MONITOR” mode with CONSULT-III.
2. Start engine and warm it up to the normal operating temperature.
3. Maintain the following conditions for at least 6 consecutive seconds. Hold the accelerator pedal as steady
as possible.
CAUTION:
Always drive at a safe speed.
4. Stop vehicle with engine running and let engine idle for 10 seconds.
5. Check 1st trip DTC.
With GST
Follow the procedure “With CONSULT-III” above.
Is 1st trip DTC detected?
YES >> Go to EC-137, "Diagnosis Procedure"
NO >> GO TO 3.
3.PERFORM DTC CONFIRMATION PROCEDURE-II
With CONSULT-III
1. Maintain the following conditions for at least 20 consecutive seconds.

DTC LogicINFOID:0000000003856718
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".

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.
