1. Drive the vehicle. And depress the accelerator pedal until vehicle speed is 90 km/h (56 MPH), then
release the accelerator pedal and keep it released for more than 10 seconds.
2. Depress the accelerator pedal until vehicle speed is 90 km/h (56 MPH) again
NOTE:
• Checking the vehicle speed with GST is advised.
• When steady-state driving is performed again even afte r it is interrupted, each diagnosis can be conducted.
In this case, the time required for diagnosis may be extended.
>> GO TO 7.

• Operate vehicle following the driving pattern shown in the figure.
• Release the accelerator pedal during deceleration of vehicle speed
from 90 km/h (56 MPH) to 0 km/h (0 MPH).
>> GO TO 8.

tain the speed.
- Release the accelerator pedal fully at least 5 seconds.
- Repeat the above two steps at least 5 times.
>> GO TO 9.
9.PATTERN 5
• The accelerator pedal must be held very steady during steady-state driving.
• If the accelerator pedal is moved, the test must be conducted again.
>> GO TO 10.
10.PATTERN 6
• Cool down the engine so that the engine c oolant temperature lowers between 15 – 35°C (59 – 95 °F).
CAUTION:
Never turn the ignition switch ON while cooling down the engine.

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.

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 detec ted after changing engine oil or changing driving con-
ditions.
>> INSPECTION END
6.CHECK FUEL PRESSURE
Check fuel pressure. (Refer to EC-687, "Work Procedure"
.)
Is the inspection result normal?
YES >> GO TO 9.
NO-1 >> Fuel pressure is too high: Replace “f uel filter and fuel pump assembly”, refer to FL-6, "Removal
and Installation", 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”, refer to FL-6, "Removal and Installation", and then
GO TO 8.
NO >> Repair or replace malfunctioning part and then GO TO 8.
