Fluid Leakage and Fluid Level Check 

Inspect for fluid leakage and check the fluid level. Refer to 

CVT-14, "Checking CVT Fluid"

 .

Fluid Condition Check

Inspect the 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
CVT fluid temperature is 50 - 80

°

C (122 - 176

°

F). Inspect the

amount of CVT fluid. Replenish if necessary.

3.

Securely engage the parking brake so that the tires do not turn.

4.

Install a tachometer where it can be seen by driver during test.

It is good practice to mark the point of specified engine
rpm on indicator.

5.

Engine start, apply foot brake, and place selector lever in “D”
position.

While holding down the foot brake, gradually press down the
accelerator pedal.

7.

Quickly read off the stall speed, and 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.

8.

Move the selector lever to the “N” position.

9.

Cool down the CVT fluid.

CAUTION:

Run the engine at idle for at least one minute.

10. Repeat steps 5 through 9 with selector lever in “R” position.

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 CVT fluid reaches in the range of 50 - 80

°

C

(122 - 176

°

F), then inspect the amount of CVT fluid and replenish if necessary.

NOTE:
The CVT fluid temperature rises in the range of 50 - 80

°

C (122 - 176

°

F) during 10 minutes of driving.

3.

After warming up CVT, remove the oil pressure detection plug and install the oil pressure gauge [special
service tool: ST2505S001 (J-34301-C)].

CAUTION:

When using the oil pressure gauge, be sure to use the O- ring attached to the oil pressure detec-
tion plug.

4.

Securely engage the parking brake so that the tires do not turn.

5.

Start the engine, and then measure the line pressure at both idle
and the stall speed.

CAUTION:

Keep the brake pedal pressed all the way down during
measurement.

When measuring the line pressure at the stall speed,
refer to 

CVT-40, "STALL TEST"

 . 

6.

After the measurements are complete, install the oil pressure
detection plug and tighten to the specified torque below.

CAUTION:

 Do not reuse the O-ring.

Road Test

ACS004MG

DESCRIPTION

The purpose of the test is to determine overall performance of
CVT and analyze causes of problems.

The road test consists of the following three parts:

1.

“Check Before Engine Is Started” 

CVT-47

 .

2.

“Check at Idle” 

CVT-47

 .

3.

“Cruise Test” 

CVT-51

 .

Before road test, familiarize yourself with all test procedures
and items to check.

perform tests on all items until specified symptom is found.
Troubleshoot items which check out No Good after road test.
Refer to 

CVT-27, "ON BOARD DIAGNOSTIC (OBD) SYS-

TEM"

 .

CONSULT-II SETTING PROCEDURE

CAUTION:

If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which carry out CAN communication.

Using CONSULT-II, perform a cruise test and record the result.

Print the result and ensure that shifts and lock-ups take place as
per Shift Schedule.

1.

Turn ignition switch OFF.

2.

Connect CONSULT-II and CONSULT-II CONVERSTER to data
link connector, which is located in lower instrument panel on
driver side.
