Inspections Before Trouble DiagnosisECS00FX0
A/T FLUID CHECK
A/T Fluid Leakage and A/T Fluid Level Check
Inspect for A/T fluid leakage and check the A/T fluid level. Refer toAT-12, "Checking A/T Fluid".
A/T Fluid Condition Check
Inspect the A/T fluid condition.
STALL TEST
Stall Test Procedure
1. Inspect the amount of engine oil. Replenish the engine oil if necessary.
2. Drive for about 10 minutes to warm up the vehicle so that the A/
Tfluidtemperatureis50to80°C(122to176°F). Inspect the
amount of ATF. Replenish if necessary.
3. Securely engage the parking brake so that the tires do not turn.
4. Engine start, apply foot brake, and place selector lever in “D”
position.
5. While holding down the foot brake, gradually press down the
accelerator pedal.
6. Quickly read off the stall speed, then quickly remove your foot
from the accelerator pedal.
CAUTION:
Do not hold down the accelerator pedal for more than 5 sec-
onds during this test.
7. Move selector lever to the “N” position.
8. Cool down the ATF.

CAUTION:
Run the engine at idle for at least 1 minute.
9. Repeat steps 5 through 8 with selector lever in “3”, “2”, “1” and “R” positions.

H: Stall speed higher than standard value
L: Stall speed lower than standard value

LINE PRESSURE TEST
Line Pressure Test Port
Line Pressure Test Procedure
1. Inspect the amount of engine oil and replenish if necessary.
2. Drive the car for about 10 minutes to warm it up so that the ATF reaches in range of 50 to 80°C(122to
176°F), then inspect the amount of ATF and replenish if necessary.
NOTE:
The A/T fluid temperature rises in range of 50 to 80°C (122 to 176°F) during 10 minutes of driving.
3. After warming up remove the oil pressure detection plug and
install the oil pressure gauge (ST2505S001).
CAUTION:
When using the oil pressure gauge, be sure to use O-ring
attached to the oil pressure detection plug.

4. Securely engage the parking brake so that the tires do not turn.
5. Start the engine, then measure the line pressure at both idle and
the stall speed.
CAUTION:
lKeep the brake pedal pressed all the way down during
measurement.
lWhen measuring the line pressure at the stall speed.
Refer toAT-43, "
STALL TEST".
6. After the measurements are complete, install the oil pressure
detection plug and tighten to the specified torque. Refer toAT-
251, "Components".

For example
lOil pump wear
lPressure regulator valve or plug sticking or spring fatigue
lOil strainer

pressure regulator valve passage oil leak
lEngine idle speed too low
Only low for a specific
positionPossible causes include an oil pressure leak in a passage or device related to the position
after the pressure is distributed by the manual valve.
HighPossible causes include a sensor malfunction or malfunction in the line pressure adjustment
function.
For example
lAccelerator pedal position signal malfunction
lA/T fluid temperature sensor malfunction
lLine pressure solenoid malfunction (sticking in OFF state, filter clog, cut line)
lPressure regulator valve or plug sticking
