INSPECTION

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.

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), adapter
(SST: 25055000), oil pressure gauge set (commercial service
tool).

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

to 

TM-306, "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”, “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
• Pressure control solenoid A (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
• Pressure control solenoid A (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 
pressure adjustment function.
For example
• Accelerator pedal position signal malfunction
• Pressure control solenoid A (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.

ROAD TEST

ROAD TEST

Description

INFOID:0000000003806508

DESCRIPTION

• The purpose of the test is to determine the overall performance of

CVT and analyze causes of problems.

• The road test consists of the following three parts:

1.

“Check Before Engine Is Started” 

TM-310

.

2.

“Check at Idle” 

TM-311

.

3.

“Cruise Test” 

TM-312

.

• Before the road test, familiarize yourself with all test procedures

and items to check.

• Perform tests for all the check items until a malfunction phenome-

non is detected. Perform diagnosis for NG items after the comple-
tion of road tests. 

CONSULT-III SETTING PROCEDURE

• Using CONSULT-III, 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.

Touch “Data Monitor” on “Direct Diagnostic Mode” screen.

2.

Touch “MAIN SIGNALS” to set recording condition.

3.

See “Numerical Display”, “Barchart Display” or “Line Graph Display”.

4.

Touch “START”.

5.

When performing cruise test. Refer to 

TM-312, "Cruise Test"

.

6.

After finishing cruise test part, touch “RECORD”.

7.

Touch “STORE”.

8.

Touch “BACK”.

9.
