CVT FLUID COOLER SYSTEM

17. Perform “CVT FLUID COOLER DIAGNOSIS PROCEDURE”.

CVT FLUID COOLER DIAGNOSIS PROCEDURE

NOTE:

Insufficient cleaning of the cooler inlet hose exterior may lead to inaccurate debris identification.
1. Position an oil pan under the transaxle's inlet and outlet cooler hoses.
2. Clean the exterior and tip of the cooler inlet hose.
3. Insert the extension adapter hose of a can of Transmission

Cooler Cleaner into the cooler outlet hose.

CAUTION:

• Wear safety glasses and rubber gloves when spraying the

Transmission Cooler Cleaner.

• Spray Transmission Cooler Cleaner only with adequate

ventilation.

• Avoid contact with eyes and skin.

• Never breath vapors or spray mist.

4. Hold the hose and can as high as possible and spray Transmis-

sion Cooler Cleaner in a continuous stream into the cooler outlet

hose until CVT fluid flows out of the cooler inlet hose for 5 sec-

onds.

5. Tie a common white, basket-type coffee filter to the end of the

cooler inlet hose.

6. Insert the tip of an air gun into the end of the cooler outlet hose.
7. Wrap a shop rag around the air gun tip and end of cooler outlet

hose.

8. Blow compressed air regulated to 5 to 9 kg/cm

(70 to 130 psi)

through the cooler outlet hose to force any remaining CVT fluid

into the coffee filter.

9. Remove the coffee filter from the end of the cooler inlet hose.
10. Perform “CVT FLUID COOLER INSPECTION PROCEDURE”.

CVT FLUID COOLER INSPECTION PROCEDURE

1. Inspect the coffee filter for debris.
a. If small metal debris less than 1 mm (0.040 in) in size or metal

powder is found in the coffee filter, this is normal. If normal

debris is found, the CVT fluid cooler/radiator can be reused and

the procedure is ended.

b. If one or more pieces of debris are found that are over 1 mm

(0.040 in) in size and/or peeled clutch facing material is found in

the coffee filter, the fluid cooler is not serviceable. The radiator/

fluid cooler must be replaced and the inspection procedure is

ended.

CVT FLUID COOLER FINAL INSPECTION

After performing all procedures, ensure that all remaining oil is cleaned from all components.

INSPECTION

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.

NOTE:

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:

Never 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 1 minute.

10. Repeat steps 6 through 9 with selector lever in “R” position.

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

(122 to 176

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

NOTE:

The CVT fluid temperature rises in the range of 50 to 80

C (122 to 176

F) during 10 minutes of driv-

ing.

3. After warming up CVT, remove the oil pressure detection plug

and install the joint pipe adapter (SST: KV31103600) (A),

adapter (SST: 25054000) (B), oil pressure gauge set (commer-

cial service tool) (C).

CAUTION:

When using the oil pressure gauge, be sure to use the 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, 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

TM-226, "Inspection and Judgment"

6. After the measurements are complete, install the oil pressure

detection plug and tighten to the specified torque below.

CAUTION:

• Never reuse O-ring.

• Apply CVT fluid to O-ring.

Judgment Possible

cause

Idle speed

Low for all positions
(“P”, “R”, “N”, “D”)

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 spe-
cific 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 func-
tion.
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 function.
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 posi-
tion.

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 spe-
cific position

Possible causes include an oil pressure leak in a passage or device related to the position after
