ON−VEHICLE INSPECTION
1. CHECK ENGINE OIL LEVEL
(a) Warm up the engine. Stop the engine, then wait for 5 minutes.
(b) Check that the engine oil level is between the 2 marks on the oil level gage.
If low, check for leakage and add oil up to the upper mark.
NOTICE:
Do not fill with engine oil above the upper mark.
2. CHECK ENGINE OIL QUALITY
(a) Check the oil for deterioration, water intrusion, discoloring
or thinning.
If the quality is visibly poor, replace the oil.
Oil grade:
Use ACEA B1, API grade CF−4, CF or G−DLD−1.
(You may also use API CE or CD.)
SAE 5W−30 is the best choice for your vehicle in
terms of good fuel economy and good starting in cold
weather.
3. REMOVE OIL PRESSURE SWITCH ASSY
(a) Disconnect the oil pressure switch connector.
(b) Using a deep socket wrench 24mm, remove the oil pres-
sure switch.
4. INSTALL OIL PRESSURE GAUGE
(a) Install the oil pressure gauge.
5. WARM UP ENGINE
6. CHECK OIL PRESSURE
Oil pressure:
At idle29 kPa (0.3 kgf/cm2, 4.3 psi) or more
At 4,500 rpm245 to 588 kPa (2.5 to 6.0 kgf/cm2, 36 to 85 psi) or more
7. REMOVE OIL PRESSURE GAUGE

HYDRAULIC TEST
1. PERFORM HYDRAULIC TEST
(a) Measure the line pressure.
NOTICE:

Perform the test at the normal operating ATF (Automatic Transmission Fluid) temperature 50
to 80
C (122 to 176
F).

The line pressure test should always be carried out in pairs. One technician should observe
the conditions of wheels or wheel stopper outside the vehicle while the other is doing the test.

Be careful to prevent SST’s hose from interfering with the exhaust pipe.

This check must be conducted after checking and adjusting engine.

Perform under condition that A/C is OFF.

When conducting stall test, do not continue more than 10 seconds.
(1) Warm up the ATF.
(2) Remove the test plug on the left side of the trans-
axle case and connect SST.
SST 09992–00095 (09992– 00231, 09992–00271)
(3) Fully apply the parking brake and chock the 4
wheels.
(4) Connect an Intelligent Tester II to the DLC3.
(5) Start the engine and check idling speed.
(6) Keep your left foot pressing firmly on the brake ped-
al and shift into D position.
(7) Measure the line pressure when the engine is idling.
(8) Depress the accelerator pedal all the way down.
Quickly read the highest line pressure when engine
speed reaches stall speed.
(9) In the same way, do the test in R position.
Specified line pressure:
ConditionD position kPa (kgf / cm2, psi)R position kPa (kgf / cm2, psi)
Idling372 to 412 kPa
(3.8 to 4.2 kgf/cm2, 54 to 60 psi)

MECHANICAL SYSTEM TESTS
1. PERFORM MECHANICAL SYSTEM TESTS
(a) Measure the stall speed.
The object of this test is to check the overall performance of the transaxle and engine by measuring
the stall speeds in the D and R positions.
NOTICE:

Perform the test at the normal operating ATF (Automatic Transmission Fluid) temperature 50
to 80
C (122 to 176
F).

Do not continuously run this test for longer than 10 seconds.

To ensure safety, do this test in a wide, clear level area which provides good traction.

The stall test should always be carried out in pairs. One technician should observe the condi-
tions of wheels or wheel stoppers outside the vehicle while the other is doing the test.
(1) Chock the 4 wheels.
(2) Connect an Intelligent Tester II to the DLC3.
(3) Fully apply the parking brake.
(4) Keep your left foot pressed firmly on the brake pedal.
(5) Start the engine.
(6) Shift into the D position. Press all the way down on the accelerator pedal with your right foot.
(7) Quickly read the stall speed at this time.
Stall speed: 2,400
150 rpm
(8) Do the same test in the R position.
Stall speed: 2,400
150 rpm
Evaluation:
ProblemPossible cause
(a) Stall engine speed is low in D and R positions

Engine power output may be insufficient

Stator one–way clutch not operating properly
HINT: If the value is less than the specified value by 600 rpm or
more, the torque converter could be faulty.
(b) Stall engine speed is high in D position

Line pressure is too low

Forward clutch slipping

One–way clutch No.2 not operating properly
(c) Stall engine speed is high in R position

Line pressure is too low

Reverse clutch slipping

1st and reverse brake slipping
(d) Stall engine speed is high in D and R positions
Line pressure is too low

Improper fluid level

(b) Measure the time lag.
(1) When the shift lever is shifted while the engine is idling, there will be a certain time lapse or lag
before the shock can be felt. This is used for checking the condition of the direct clutch, forward
clutch, and 1st and reverse brake.
NOTICE:

Perform the test at the normal operating ATF temperature 50 to 80
C (122 to 176
F).

Be sure to allow 1 minute interval between tests.

Perform the test three times, and measure the time lags. Calculate the average value of the three
time lags.
(2) Connect an Intelligent Tester II to the DLC3.
(3) Fully apply the parking brake.
(4) Start and warm up the engine and check idle speed.
Idle speed: approx. 700 rpm (In N position and A/C OFF)
(5) Shift the lever from N to D position. Using a stop watch, measure the time from when the lever
is shifted until the shock is felt.
Time lag: N → D less than 1.2 seconds
(6) In the same way, measure the time lag for N → R.
Time lag: N → R less than 1.5 seconds
Evaluation (If N → D or N → R time lag is longer than the specified):
ProblemPossible cause
N → D time lag is longer

Line pressure is too low

Forward clutch worn

One–way clutch No.2 not operating properly
N → R time lag is longer

Line pressure is too low

Reverse clutch worn

1st and reverse brake worn

(c) Check the indicator.
(1) Turn the ignition switch to the ON position.
(2) Check that the CRUISE main indicator light comeson when the cruise control main switch ON–OFF
button is pushed on, and that the indicator light
goes off when the ON–OFF button is pushed off.
HINT:
If there is a problem with the indicator light, inspect the CRUISE
main indicator light circuit ( see page 05–327).
HINT:
If a malfunction occurs in the vehicle speed sensors, stop lamp
switch assy or other related parts during cruise control driving,
the ECM actuates AUTO CANCEL of the cruise control. Then
the CRUISE main indicator light starts to blink, informing the
driver of the malfunction. At the same time, data of the malfunc-
tion is stored as a diagnostic trouble code (DTC).
