STALL TEST
STALL TEST
Work ProcedureINFOID:0000000009464233
INSPECTION
1. Check the engine oil level. Replenish if necessary. Refer to
LU-25, "Inspection".
2. Check for leak of the CVT fluid. Refer to TM-377, "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 sh ift the selector lever to “D” position.
6. While depressing the brake pedal, depress the accelerator pedal gradually.
7. Read the stall speed quickly and release your foot from the accelerator pedal quickly. CAUTION:
Do not depress the accelerator pedal for 5 seconds or more during the test.
8. Shift the selector lever to “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.
NARROWING-DOWN MALFUNCTIONING PARTS
O: Within the stall speed standard value.
H: Stall speed is higher than the standard value.
L: Stall speed is lower than the standard value.
Stall speed : Refer to TM-413, "Stall Speed".

CVT POSITION
InspectionINFOID:0000000009464234
1. Turn ON the ignition switch with the shift selector at the “P” position.
2. Press the shift selector button with the brake pedal depressed, and confirm that the shift selector can be
moved to positions other than “P”. Also confirm that movement is not allowed from the “P” position to other
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. Make sure that the shift selector is moved to all the shift posi- tions in the manner shown.
• (A): Press shift selector button to operate shift selector, while depressing the brake pedal.
• (B): Press shift selector button to operate shift selector.
• (C): Shift selector can be operated without pressing the shift selector button.
6. When the shift selector button is pressed without applying for- ward/backward force to the shift selector at “P”, “R”, “N”, “D” or
“Ds” positions, there should be no “sticking” on the shift selector
button operation.
7. Check that the back-up lamps do not illuminate when the shift selector is in the “P” position.
8. Check that the engine can be started with the sh ift selector in the “P” and “N” positions only.
9. Check that the transaxle is locked completely when the shift selector is in the “P” position.
AdjustmentINFOID:0000000009464235
1. Shift the shift selector to the “P” position.
CAUTION:
Turn wheels at least a quarter turn and be certain the park position mechanism is fully engaged.
2. Loosen the control cable nut. CAUTION:
Do not apply force to the manual lever.
3. Position the manual lever in the “P” position.
4. Tighten the control cable nut to specified torque. Refer to TM-
380, "Exploded View".
CAUTION:
Hold manual lever when tightening.

DTC CONFIRMATION PROCEDURE
CAUTION:
Be careful of the driving speed.
1.PREPARATION BEFORE WORK
If another "DTC CONFIRMATION PROCEDURE" occurs just before, turn ignition switch OFF and wait for at
least 10 seconds, then perform the next test.
>> GO TO 2.
2.PREPARATION BEFORE OPERATION
With CONSULT
1. Start the engine.
2. Select “Data Monitor” in “TRANSMISSION”.
3. Select “FLUID TEMP”.
4. Confirm that the CVT fluid temper ature is in the following range.
With GST
1. Start the engine.
2. Set the CVT fluid to 20 °C (68 °F) or more.
NOTE:
When the ambient temperature is 20 °C (68 °F), the CVT fluid usually increases to 50 to 80 °C (122 to
176 °F) with driving in an urban area for approximately 10 minutes.
Is the CVT fluid 20
°C (68°F) or more?
YES >> GO TO 3.
NO >> 1. Warm the transaxle. 2. GO TO 3.
3.CHECK DTC DETECTION
1. Drive the vehicle.
2. Maintain the following conditions for 10 seconds or more.
3. Stop the vehicle.
4. Check the first trip DTC.
Is
“P0740” detected?
YES >> Go to TM-323, "Diagnosis Procedure".
