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 5
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:
2,150 to 2,450 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).
(c) Allow the engine to idle with the air conditioning
OFF.
Test Result Possible Cause
