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.

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
