Question sheetINFOID:0000000012431041
DESCRIPTION
There are many operating conditions that may cause a malfunction
of the transmission parts. By understanding those conditions prop-
erly, a quick and exact diagnosis can be achieved.
In general, perception of a problem varies depending on individuals.
Ask the customer about his/her concer ns carefully. It is important to
understand the phenomenon or status. To systemize all the informa-
tion for the diagnosis, prepare the question sheet referring to the
question points.
In some cases, multiple conditions that appear simultaneously may
cause a DTC to be detected.

Work ProcedureINFOID:0000000012431048
INSPECTION
1. Check the engine oil level. Replenish if necessary.
2. Check for leak of the CVT fluid. Refer to TM-228, "
Inspection".
3. 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).
4. Be sure to apply the parking brake and block the tires.
5. Start the engine, depress the brake pedal and put the selector lever to the D position.
6. While depressing the brake pedal, depress the accelerator pedal gradually.
7. Read the stall speed quickly. Then, release your foot from the accelerator pedal quickly. CAUTION:

8. Place the selector lever in the N position.
9. Cool the CVT fluid. CAUTION:
Run the engine with the idle speed for at least 1 minute.
10. Put the selector lever to the R position and perform Step 6 to Step 9 again.

LINE PRESSURE TEST
Work ProcedureINFOID:0000000012431049
INSPECTION
1. Check the engine oil level. Replenish if necessary. Refer to
LU-7, "Inspection".
2. Check for CVT fluid leaks. Refer to TM-228, "
Inspection".
3. 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).
4. Stop the vehicle, apply the parking brake and block the tires.
5. Start the engine.
6. Select “Data Monitor” in “TRANSMISSION”.
7. Select “LINE PRESSURE”.
8. Measure the line pressure at both idle and the stall speed. CAUTION:
Keep brake pedal pressed all the way down during measurement.
NARROWING-DOWN MALFUNCTIONING PARTS
Line pressure : TM-265, "Line Pressure"
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
• Damage of chain and sprocket
• 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
Stal l s pe ed 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:
•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:
• Oil pump wear
• 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.

CVT POSITION
InspectionINFOID:0000000012431050
1. Turn ON the ignition switch with the shift selector in the "P" position.
2. Press the shift selector handle button with the brak e pedal depressed, and confirm that the shift selector
can be moved from the "P" position. Also confirm that shift selector will not move from the "P" position
without depressing the brake pedal.
3. Move the shift selector and check for “excessive effort,” “sticking,” “noise” or “rattle”.
4. Confirm that shift selector stops at each position with the feel of engagement when it is moved through all
the positions. Check whether or not the actual position the shift selector is in matches the position shown
by the transaxle body.
5. The method of operating the shift selector to individual positions correctly should be as shown.
• (A): Press shift selector button to operate shift selector, whiledepressing the brake pedal.
• (B): Press shift selector button to operate shift selector.
• (C): Shift selector can be operated without pressing shift selector button.
6. When the shift selector handle button is pressed without apply- ing forward/backward force to the shift selector at “P”, “R”, “N”
and “D” positions, there should be no “sticking” of the button.
7. Confirm the back-up lamps illuminate only when shift selector is placed in the “R” position. Confirm the back-up lamps do not illu-
minate when the shift selector is pushed toward the “R” pos ition side when shift selector is in the “P” or “N”
position.
8. Check that the engine can be started only when the shift selector is in the “P” and “N” positions.
9. Check that the transaxle is locked when t he shift selector is in the "P" position.
AdjustmentINFOID:0000000012431051
1. Move the shift selector to the “P” position.
CAUTION:
Rotate the wheels at least a quarter turn and be certain the transaxle is locked in the "P" position.
2. Remove nut (A) and set manual lever (B) to the “P” position. CAUTION:
Do not apply force to the manual lever.
3. Tighten nuts to the specified torque. Refer to TM-234, "
Exploded
View".
CAUTION:
Do not move the manual lever when tightening.

DTC/CIRCUIT DIAGNOSIS
U0073 COMMUNICATION BUS A OFF
DescriptionINFOID:0000000012431053
CAN (Controller Area Network) is a serial communication line for real-time application. It is an on-vehicle mul-
tiplex communication line with high data communica tion speed and excellent malfunction detection ability.
Many electronic control units are equipped onto a vehicle, and each control unit shares information and links
with other control units during operation (not independently ). In CAN communication, control units are con-
nected with 2 communication lines (CAN-H line, CAN-L li ne) allowing a high rate of information transmission
with less wiring. Each control unit transmits/receives data but selectively reads required data only.
