MECHANICAL SYSTEM TESTS
1. STALL SPEED TEST
HINT:
This test is to check the overall performance of the
engine and transaxle.
NOTICE:
• Do not perform the stall speed test longer than 10
seconds.
• To ensure safety, perform this test in an open and
level area that provides good traction.
• The stall speed test should always be performed
with at least 2 people. One person should observe
the condition of the wheels and wheel chocks
while the other is performing the test.
(a) Connect the intelligent tester to the CAN VIM. Then
connect the CAN VIM to the DLC3.
(b) Run the vehicle until the transmission fluid
temperature has reached 50 to 80
C (122 to 176F).
(c) Allow the engine to idle with the air conditioning
OFF.
(d) Chock all 4 wheels.
(e) Set the parking brake and keep the brake pedal
depressed firmly with your left foot.
(f) Move the shift lever to the D position.
(g) Depress the accelerator pedal as much as possible
with your right foot.
(h) Read the engine rpm (stall speed) and release the
accelerator pedal immediately.
Standard value:
2,450 to 2,750 rpm
Evaluation:
NOTICE:
Perform the test at the normal operating ATF
temperature of 50 to 80
C (122 to 176F).
2. SHIFT TIME LAG TEST
HINT:
This test is to check the condition of the direct clutch,
forward clutch, 1st brake and reverse brake.
(a) Connect the intelligent tester to the CAN VIM. Then
connect the CAN VIM to the DLC3.
(b) Run the vehicle until the transmission fluid
temperature has reached 50 to 80
C (122 to 176F).
Test Result Possible Cause
Stall speed is lower than standard value • Engine power output may be insufficient
• Stator one-way clutch not operating properly
HINT:
If the value is less than the specified value by 600 rpm or more, the
torque converter could be faulty.
Stall speed is higher than standard value • Line pressure is too low
• Forward clutch slipping
• U/D (underdrive) brake slipping
• U/D (underdrive) one-way clutch is not operating properly
• No. 1 one-way clutch not operating properly
• Improper fluid level

(c) Allow the engine to idle with the air conditioning
OFF.
(d) Set the parking brake and keep the brake pedal
depressed firmly.
(e) Check the D range time lag.
(1) Move the shift lever to N and wait for 1 minute.
(2) Move the shift lever to D and measure the time
until the shock is felt.
(3) Repeat the 2 procedures above 3 times, and
calculate the average time of the 3 tests.
(f) Check the R range time lag.
(1) Move the shift lever to N and wait for 1 minute.
(2) Move the shift lever to R and measure the time
until the shock is felt.
(3) Repeat the 2 procedures above 3 times, and
calculate the average time of the 3 tests.
Standard value:
D range time lag is less than 1.2 seconds
R range time lag is less than 1.5 seconds
Evaluation:
Test Result Possible Cause
D range time lag exceeds standard value • Line pressure is too low
• Forward clutch worn
• No. 1 one-way clutch is not operating properly
• U/D (underdrive) one-way clutch is not operating
• U/D (underdrive) brake worn
R range time lag exceeds standard value • Line pressure is too low
• Reverse clutch worn
• 1st and reverse brake worn
• U/D (underdrive) brake worn

HYDRAULIC TEST
1. PERFORM HYDRAULIC TEST
(a) Measure the line pressure.
NOTICE:
• Perform the test at the normal operating ATF
temperature: 50 to 80
C (122 to 176F).
• The line pressure test should always be
performed with at least 2 people. One person
should observe the condition of the wheels or
wheel chocks while the other is performing
the test.
• Be careful to prevent SST's hose from
interfering with the exhaust pipe.
• This test must be performed after checking
and adjusting the engine.
• Perform the test with the A/C OFF.
• When conducting the stall test, do not
continue for more than 10 seconds.
(1) Warm up the ATF (Automatic Transmission
Fluid).
(2) Lift the vehicle up.
(3) Remove the engine under cover.
(4) Connect the intelligent tester to the DLC3.
(5) Remove the test plug A on the transaxle case
front left side and install SST.
SST 09992-00095 (09992-00231, 09992-
00271)
NOTICE:
There is a difference between the installation
point of the D position and R position.
(6) Start the engine.
(7) Using intelligent tester, shift to D position and
hold 3rd gear by active test, and measure the
line pressure in idling.
Specified line pressure:
(8) Turn the ignition switch off.
(9) Disconnect the connector of the transmission
wire.
HINT:
Disconnect the connector only when performing
the position stall test.
(10)Start the engine.
(11)Firmly depress the brake pedal, shift to the D
position, depress the accelerator pedal all the
way down and check the line pressure while the
stall test is performed.

ROAD TEST
1. PROBLEM SYMPTOM CONFIRMATION
(a) Based on the result of the customer problem
analysis, try to reproduce the symptoms. If the
problem is that the transaxle does not shift up, shift
down, or the shift point is too high or too low,
conduct the following road test referring to the
automatic shift schedule and simulate the problem
symptoms.
2. ROAD TEST
NOTICE:
Perform the test at the normal operating ATF
temperature of 50 to 80
C (122 to 176F).
(a) D position test
Move the shift lever to D and fully depress the
accelerator pedal. Check the following:
(1) Check up-shift operation.
Check that the 1
2, 2 3 and 3 O/D up-
shifts take place at the shift point shown in the
automatic shift schedule (see page SS-60).
HINT:
O/D Gear Up-shift Prohibition Control
• Engine coolant temperature is 55
C (131F)
or less and vehicle speed is at 70 km/h (43
mph) or less.
• ATF temperature is 5
C (41F) or less.
O/D Gear Lock-up Prohibition Control
• Brake pedal is depressed.
• Accelerator pedal is released.
• Engine coolant temperature is 60
C (140F)
or less.
(2) Check for shift shock and slip.
Check for shock and slip at the 1
2, 2 3 and
3
O/D up-shifts.
(3) Check for abnormal noise and vibration.
Check for abnormal noise and vibration when
up-shifting from 1
2, 2 3 and 3 O/D while
driving with the shift lever on D, and check while
driving in the lock-up condition.
HINT:
The check for the cause of abnormal noise and
vibration must be done thoroughly as it could
also be due to loss of balance in the differential,
torque converter clutch, etc.
(4) Check kick-down operation.
While driving the vehicle in the 2nd, 3rd and O/D
gears with the shift lever on D, check that the
possible kick-down vehicle speed limits for 2

1, 3
2 and O/D 3 kick-downs conform to
those indicated in the automatic shift schedule
(see page SS-60).
(5) Check for abnormal shock and slip at kick-down.
