(b) Clear the DTC.
The following actions will erase the DTCs and
freezed frame data.
Operating the OBDII scan tool (complying with SAE
J1978) or TOYOTA hand−held tester to erase the
codes (See the TOYOTA hand−held tester or OBD
II scan tool’s instruction book for operating instruc-
tions.).
NOTICE:
If the TOYOTA hand−held tester switches the ECM from the
normal mode to the check mode or vice−versa, or if the
ignition switch is turned from ON to ACC or OFF during the
check mode, the DTCs and freezed frame data will be
erased.
(c) Inspect the DLC3.
The vehicle’s ECM uses V.P.W. (Variable Pulse Width) for
communication to comply with SAE J1850. The terminal
arrangement of DLC3 complies with SAE J1962 and
matches the V.P.W. format.
Terminal No.Connection/Voltage or ResistanceCondition

HINT:
If your display shows ”UNABLE TO CONNECT TO VEHICLE”
when you have connected the cable of the OBD II scan tool or
TOYOTA hand−held tester to the DLC3, turned the ignition
switch ON and operated the scan tool, there is a problem on the
vehicle side or tool side.
If communication is normal when the tool is connected to
another vehicle, inspect the DLC3 on the original vehicle.
If communication is still not possible when the tool is con-
nected to another vehicle, the problem is probably in the
tool itself, so consult the Service Department listed in the
tool’s instruction manual.

4. CHECK FOR INTERMITTENT PROBLEMS
TOYOTA hand−held tester only:
By putting the vehicle’s ECM in check mode, 1 trip detection logic is possible instead of 2 trip detection logic
and sensitivity to detect open circuits is increased. This makes it easier to detect intermittent problems.
(1) Clear the DTCs (See step 3).
(2) Set the check mode (See step 3).
(3) Do simulation test (See page IN−20).
(4) Check the connector connection and terminal (See page IN−30).
(5) Visual check and contact pressure (See page IN−20).
(6) Handle the connector (See page IN−20).
5. PROBLEM SYMPTOM CONFIRMATION
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 up−shift, down−shift, or the shift point is too high or too
low, conduct the following road test to confirm the automatic shift schedule and simulate the problem symp-
toms.
6. ROAD TEST
NOTICE:
Do the test at normal operating ATF temperature 50 − 80°C (122 − 176°F).
(a) D position test.
Shift into the D position, keep the accelerator pedal constant at the full throttle valve opening position
and check the following points:
(1) Check up− shift operation.
Check that 1 → 2, 2 → 3 and 3 → O/D up−shift takes place, at the shift point shown in the automat-
ic shift schedule (See page SS−32).
HINT:
O/D Gear Up−shift Prohibition Control:
Engine coolant temperature is 50°C (122°F) or less.
If there is a 10km/h (6 mph) difference between the set cruise control speed and vehicle speed.
O/D main switch is pushed ON (During the O/D OFF indicator light lights up.).
O/D Gear Lock−up Prohibition Control:
Brake pedal is depressed.
Engine coolant temperature is 50°C (122°F) 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.
Run at the D position lock−up or O/D gear and check for abnormal noise and vibration.
HINT:
The check for the cause of abnormal noise and vibration must be performed very thoroughly as it could also
be due to loss of balance in the torque converter clutch, etc.
(4) Check kick−down operation.
While running in the D position, 2nd, 3rd and O/D gears, check that the possible kick−down ve-
hicle speed limits for 2 → 1, 3 → 2 and O/D → 3 kick−downs conform to those indicated on the
automatic shift schedule (See page SS−32).
(5) Check abnormal shock and slip at kick−down.
(6) Check the lock−up mechanism.
Drive in the D position, O/D gear, at a steady speed (lock−up ON) of about 75 km/h (47
mph).
Lightly depress the accelerator pedal and check that the RPM does not change abruptly.
If there is a big jump in RPM, there is no lock−up.

valve opening position, check on the following points:
(1) Check up−shift operation.
Check that the 1 → 2 up−shift takes place and that the shift point conforms to the automatic shift
schedule (See page SS−32).
HINT:
There is no O/D up−shift and lock−up in the 2 position.
(2) Check engine braking.
While running in the 2nd gear of the 2 position, release the accelerator pedal and check the en-
gine braking effect.
(3) Check for abnormal noises during acceleration and deceleration, and for shock at up−shift and
down−shift.
(c) L position test.
Shift into the L position and while driving with the accelerator pedal held constantly at the full throttle
valve opening position, check the following points:
(1) Check no up−shift.
While running in the L position, check that there in no up−shift to 2nd gear.
(2) Check engine braking.
While running in the L position, release the accelerator pedal and check the engine braking ef-
fect.
(3) Check for abnormal noises during acceleration and deceleration.
(d) R position test.
Shift into the R position and while starting at full throttle, check for slipping.
CAUTION:
Before conducting this test ensure that the test area is free from personnel and obstructions.
(e) P position test.
Stop the vehicle on a gradient (more than 5°) and after shifting into the P position, release the parking
brake. Then check that the parking lock pawl holds the vehicle in place.
