(k) Care must be taken when jacking up and supporting the
vehicle. Be sure to lift and support the vehicle at the prop-
er locations (See page IN−8).
Cancel the parking brake on the level place and
shift the transmission in Neutral (or N position).
When jacking up the front wheels of the vehicle at
first place stoppers behind the rear wheels.
When jacking up the rear wheels of the vehicle at
first place stoppers before the front wheels.
When either the front or rear wheels only should be
jacked up, set rigid racks and place stoppers in front
and behind the other wheels on the ground.
After the vehicle is jacked up, be sure to support it
on rigid racks . It is extremely dangerous to do any
work on a vehicle raised on a jack alone, even for
a small job that can be finished quickly.
(l) Observe the following precautions to avoid damage to the
following parts:
(1) Do not open the cover or case of the ECU unless absolutely necessary. (If the IC terminals are
touched, the IC may be destroyed by static electric-
ity.)
(2) To disconnect vacuum hoses, pull off the end, not the middle of the hose.
(3) To pull apart electrical connectors, pull on the con- nector itself, not the wires.
(4) Be careful not to drop electrical components, such
as sensors or relays. If they are dropped on a hard
floor, they should be replaced and not reused.
(5) When steam cleaning an engine, protect the elec- tronic components, air filter and emission −related
components from water.
(6) Never use an impact wrench to remove or install temperature switches or temperature sensors.

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 the 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 t\
o detect intermittent problems.
(1) Clear the DTC (See step 3).
(2) Set the check mode (See step 3).
(3) Do a simulation test (See page IN−18).
(4) Check the cnnector connection and terminal (See page IN−28).
(5) Visual check and contact pressure (See page IN−28).
(6) Handle the connector (See page IN−28).
5. ROAD TEST
NOTICE:
Perform the test at normal operating ATF temperature 50 − 80°C (122 − 176° F).
(a) D position test in NORM and PWR pattern positions. Shift into the D position and hold the accelerator pedal constant at the full\
throttle valve opening posi-
tion and check the following:
HINT:
When the 2nd start switch in on, there is no 1 → 2 up−shift and 2 →1 down−shift.
(1) 1 →2, 2 → 3 and 3 → O/D up−shift takes place, and shift point should conform to those shown
in the automatic shift schedule. Conduct a test under both Normal and Powe\
r patterns.
HINT:
There is no O/D up−shift or lock−up when the coolant temperature is below 55 °C (131°F ).
Evaluation:
If there is no 1 → 2 up−shift:
Shift solenoid valve No. 2 is stuck.
1−2 shift valve is stuck.
If there is no 2 → 3 up−shift:
Shift solenoid valve No. 1 is stuck.
2−3 shift valve is stuck.
If there is no 3 → O/D up−shift:
3−4 shift valve is stuck.
If the shift point is defective:
Throttle valve, 1−2 shift valve, 2−3 shift valve, 3−4 shift valve etc., are defective.

If the lock−up is defective:
Lock−up solenoid is stuck.
Lock−up control valve is stuck.
Lock−up signal value is stuck.
(2) In the same way, check the shock and slip at the 1 → 2, 2 →3 and 3 → O/D up−shift.
Evaluation:
If the shock is excessive:
Line pressure is too high.
Accumulator is defective.
Check ball is defective. (3) 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 noises and vibration must be made with \
extreme care as it could also
be due to loss of balance in the propeller shaft, differential, torque converter clutch, etc.
(4) While running in the D position, 2nd, 3rd and O/D gears, check to see that the\
possible kick −down
vehicle speed limits for 2 →1, 3 → 2 and O/D →3 kick−downs conform to those indicated on
the automatic shift schedule.
(5) Check for abnormal shock and slip at kick −down.
(6) Check for the lock −up mechanism.
Drive in D position, O/D gear, at a steady speed (lock −up ON) of about 95 km/h (59 mph).
Lightly depress the accelerator pedal and check that the engine RPM does not change
abruptly.
If there is a big jump in engine RPM, there is no lock −up.
(b) 2 position test. Shift into the 2 position and, while driving with the accelerator pedal held \
constantly at the full throttle
valve opening position, push in one of the pattern selectors and check the fo\
llowing points:
HINT:
When the 2nd start switch is on, there is no 1 → 2 up−shift and 2 →1 down−shift.
(1) Check to see that the 1 → 2 up− shift takes place and that the shift point conforms to the automatic
shift schedule.
HINT:
There is no O/D up−shift and lock−up in the 2 position. (2) While running in the 2 position and 2nd ge ar, release the accelerator pedal and check the engine
braking effect.
Evaluation:
If there is no engine braking effect:
2nd coast brake is defective. (3) Check for abnormal noise at acceleration and deceleration, and for shock at up −shift and down −
shift.
(c) L position test. (1) While running in the L position, check to see that there is no up −shift to 2nd gear.
(2) While running in the L position, release the accelerator pedal and check the engine braking ef- fect.
Evaluation:
If there is no engine braking effect:
1stand reverse brake is defective. (3) Check for abnormal noise during acceleration and deceleration.
(d) R position test. Shift into the R position and fully depress the accelerator pedal and ch\
eck for slipping.

8. HYDRAULIC TEST
Measure the line pressure.
NOTICE:
Do the test at normal operation ATF temperature 50 − 80°C (122 − 176° F).
The line pressure test should always be carried out in pairs. One techni\
cian should observe
the conditions of wheels or wheel stoppers outside the vehicle while the ot\
her is doing the test.
Be careful to prevent SST’s hose from interfering with the exhaust pipe.
(1) Warm up the ATF.
(2) Remove the test plug on the transmission case right side and connect SST\
(See page AT−18
for the location to connect SST).
SST 09992 −00094 (09992 −00150, 09992−00270)
(3) Fully apply the parking brake and chock the 4 wheels.
(4) Start the engine and check idling speed.
(5) Keep your left foot pressed firmly on the brake pedal and shift into D p\
osition.
(6) Measure the line pressure when the engine is idling.
(7) Press the accelerator pedal all the way down. Quickly read the highest line pr\
essure when engine
speed reaches stall speed.
NOTICE:
Release the accelerator pedal and stop test if the rear wheels begin to rotate before the engine speed
reaches the specified stall speed.
(8) In the same manner, do the test in R position.
Specified line pressure:
Condition D position kPa (kgf/cm2, psi) R position kPa (kgf/cm2, psi)

If the measured pressures are not up to specified values, recheck the thro\
ttle cable adjustment and retest.
