TROUBLE DIAGNOSIS
• 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 to 80 °C (122 to 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. Start engine, apply foot brake, and place selector lever in “D” position.

6. 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 accelerat or 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 1 minute.
10. Repeat steps 6 through 9 with selector lever in “R” position.
Judgement Stall Test
O: Stall speed within standard value position.
H: Stall speed is higher than standard value.
L: Stall speed is 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 CVT fluid reaches in the range of 50 to 80°C
(122 to 176 °F), then inspect the amount of CVT fluid and replenish if necessary.

TROUBLE DIAGNOSIS
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: - (OTC3492)].
CAUTION:
When using the oil pressure gauge, be sure to u se 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 duringmeasurement.
• When measuring the line pressure at the stall speed, refer
to "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 O-ring.
• Apply CVT fluid to O-ring.

Road TestINFOID:0000000005397791
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-42
.
2. “Check at Idle”CVT-42
.
3. “Cruise Test”CVT-43
.
• Before road test, familiarize yourself with all test procedures and items to check.
• Perform tests on all items until specified symptom is found. Trou-
bleshoot items which check out No Good after road test.
Judgement Possible cause
Idle speed Low for all positions
(“P”, “R”, “N”, “D”, “L”)
Possible causes include malfunctions in the pressure supply system and low oil pump output.
For example
• Oil pump wear
• Pressure regulator valve or plug sticking or spring fatigue
• Oil strainer
⇒ oil pump ⇒ pressure regulator valve passage oil leak
• Engine idle speed too low
Only low for a specific
position Possible causes include an oil pressure leak in a passage or device related to the position after
the pressure is distributed by the manual valve.
High Possible causes include a sensor malfunction or malfunction in the line pressure adjustment
function.
For example
• Accelerator pedal position signal malfunction
• CVT fluid temperature sensor malfunction
• Line pressure solenoid) malfunction (sticking in OFF state, filter clog, cut line)
• Pressure regulator valve or plug sticking
Stall speed Line pressure does
not rise higher than
the line pressure for
idle.
Possible causes include a sensor malfunction or malfunction in the pressure adjustment func-
tion.
For example
• Accelerator pedal position signal malfunction
•TCM malfunction
• Line pressure solenoid) malfunction (shorting, sticking in ON state)
• Pressure regulator valve or plug sticking
The pressure rises,
but does not enter the
standard position. Possible causes include malfunctions in the pressure supply system and malfunction in the pres-
sure adjustment function.
For example
• Accelerator pedal position signal malfunction
• Line pressure solenoid) malfunction (sticking, filter clog)
• Pressure regulator valve or plug sticking
Only low for a specific
position Possible causes include an oil pressure leak in a passage or device related to the position after
the pressure is distributed by the manual valve.
