STALL TEST
Inspection and JudgmentINFOID:0000000003849078
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 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 move selector lever to “D”
position.
6. Gradually press down accelerator pedal while holding down the
foot brake.
7. Quickly read off the stall speed, and then quickly remove your
foot from accelerator pedal.
CAUTION:
Never hold down accelerator pedal for more than 5 seconds
during this test.
8. Move selector lever to “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.

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: 25054000), 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 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 brake pedal pressed all the way down during mea-
surement.
 When measuring the line pressure at the stall speed.
Refer to TM-144, "
Inspection and Judgment".
6. Install oil pressure detection plug and tighten to the specified
torque below after the measurements are complete.
CAUTION:
 Never reuse O-ring.
 Apply CVT fluid to O-ring.

Judgment Possible cause
Idle speedLow 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
positionPossible causes include an oil pressure leak in a passage or device related to the position after
the pressure is distributed by the manual valve.
HighPossible 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
Sta ll sp ee dLine 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 pres-
sure adjustment function.
For example
 Accelerator pedal position signal malfunction
 Pressure control solenoid A (line pressure solenoid) malfunction (sticking, filter clog)

INSPECTION
1. Move selector lever to “P” position, and turn ignition switch ON (engine stop).
2. Check that selector lever can be shifted to other than “P” position when brake pedal is depressed. Also
check that selector lever can be shifted from “P” position only when brake pedal is depressed.
3. Move selector lever and check for excessive effort, sticking, noise or rattle.
4. Check that selector lever stops at each position with the feel of engagement when it is moved through all
the positions. Check that the actual position of selector lever matches the position shown by shift position
indicator and manual lever on the transaxle.
5. The method of operating selector lever to individual positions
correctly should be as shown.
6. When selector button is pressed in “P”, “R”, “N”, “D” or “L” posi-
tion without applying forward/backward force to selector lever,
check button operation for sticking.
7. Check that back-up lamps illuminate only when selector lever is
placed in the “R” position.
8. When in “R” position, check that back-up lamps illuminate even
when the selector lever is pushed toward the “P” position.
CAUTION:
Check the lighting without pressing shift button.
9. Check that back-up lamps do not illuminate when selector lever is pushed toward the “R” position when in
the “P” or “N” position.
CAUTION:
Check the lighting without pressing shift button.
10. Check that the engine can only be started with selector lever in the “P” and “N” positions.
11. Check that transaxle is locked completely in “P” position.
ADJUSTMENT
1. Move selector lever to “ P” position.
CAUTION:
Turn wheels more than 1/4 rotations and apply the park
lock.
2. Loosen the control cable nut (A).
3. Place manual lever (B) to “P” position.
