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
• 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 function.
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 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
• Pressure control solenoid A (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 
the pressure is distributed by the manual valve.

ROAD TEST

Description

INFOID:0000000000988985

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” 

TM-320

.

2.

“Check at Idle” 

TM-321

.

3.

“Cruise Test” 

TM-322

.

• 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 the malfunctioning items after road test. 

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 “SELECT DIAG 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-322, "Cruise Test"

.

6.

After finishing cruise test part, touch “RECORD”.

7.

Touch “STORE”.

8.

Touch “BACK”.

9.

Touch “DISPLAY”.

10. Touch “PRINT”.
11. Check the monitor data printed out.
