5. ACTIVE TEST
HINT:
Performing the ACTIVE TEST using the hand±held tester allows the relay, VSV, actuator and so on to oper-
ate without parts removal. Performing the ACTIVE TEST as the first step of troubleshooting is one of the
method to shorten the work time.
It is possible to display the DATA LIST during the ACTIVE TEST.
(a) Warm up the engine.
(b) Turn the ignition switch OFF.
(c) Connect the hand±held tester to the DLC3.
(d) Turn the ignition switch ON.
(e) According to the display on tester, perform the ºACTIVE TESTº.

6. PROBLEM SYMPTOM CONFIRMATION
(a) Taking into consideration the results of the customer problem analysis, try to reproduce the symptoms
of the trouble. 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.

7.ROAD TEST
NOTICE:
Conduct the test at normal operating ATF temperature 50 to 80 C (122 to 176 F).
(a)D range test Shift into the D range and fully depress the accelerator pedal and check\
the following points:
(1)Check up±shift operation.Check that 1 2, 2 3 and 3 O/D up±shift take place, and that the shift points conform to
the automatic shift schedule (See page 03±45).
HINT:
O/D Gear Up±shift Prohibition Control
Coolant temp. is 60 C (140 F) or less and vehicle speed is 70 km/h (43 mph) or less.
ATF temp. is 10 C (50 ) or less.
O/D and 3rd Gear Lock±up Prohibition Control
Brake pedal is depressed.
Accelerator pedal is released.
ATF temp. is 10 C (50 ) or less.
Coolant temp. is 60 C (140 F) or less.
When the 2nd start switch is on, there is no 1 2 up±shift and 2 1 down±shift.
(2)Check for shift shock and slip. Check for shock and slip at the 1 2, 2 3 and 3 O/D up±shift.
(3)Check for abnormal noises and vibration. Run in D range lock±up or O/D gear and check for abnormal noise and v\
ibration.
HINT:
The check for the cause of abnormal noise and vibration must be done ver\
y thoroughly as it could also be
sure to loss of balance in the differential, torque converter, etc. (4)Check kick±down operation.While running in the D range, 2nd, 3rd and O/D gears, check to see that the p\
ossible 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 03±45).
(5) Check for abnormal shock and slip at kick±down.
(6) Check the lock±up mechanism.
Drive in D range O/D gear, at a steady speed (lock±up ON) of about 70 km/h (43 mph).
Lightly depress the accelerator pedal and check that the engine speed does not change
abruptly.
If there is a big jump in engine speed, there is no lock±up.
(b) S range test Shift to the S range, depress the accelerator pedal and check the follow\
ing points:
Shift operations.
Shifting the shift lever to º+º or º±º changes the shift \
range on the combination meter.
HINT:
Manual shift prohibition control is performed when:
Down±shifting causes engine overrun.
Down±shifting is required continuously. (Down±shifting to 1st gear may not be performed.)
(c) R range test Shift into the R range and fully depress the accelerator pedal and check\
for slipping.
CAUTION:
Before conducting this test, ensure that the test area is free from peop\
le and obstruction.
(d) P range test Stop the vehicle on a grade (more than 5 ) and after shifting into the P range, release the parking
brake. Then, check to see that the parking lock pawl holds the vehicle in plac\
e.
