2. FOR VEHICLES EQUIPPED WITH A CATALYTIC CONVERTER
CAUTION:
If large amount of unburned gasoline flows into the converter, it may overheat and create a fire haz-
ard. To prevent this, observe the following precautions and explain them to your customer.
(a) Use only unleaded gasoline.
(b) Avoid prolonged idling.
Avoid running the engine at idle speed for more than 20 minutes.
(c) Avoid spark jump test.
(1) Perform spark jump test only when absolutely necessary. Perform this test as rapidly as possible.
(2) While testing, never race the engine.
(d) Avoid prolonged engine compression measurement.
Engine compression tests must be done as rapidly as possible.
(e) Do not run engine when fuel tank is nearly empty.
This may cause the engine to misfire and create an extra load on the converter.
(f) Avoid coasting with ignition turned off.
(g) Do not dispose of used catalyst along with parts contaminated with gasoline or oil.
3. IF VEHICLE IS EQUIPPED WITH MOBILE COMMUNICATION SYSTEM
For vehicles with mobile communication systems such as two-way radios and cellular telephones, observe
the following precautions.
(1) Install the antenna as far as possible away from the ECU and sensors of the vehicle's electronic
system.
(2) Install the antenna feeder at least 20 cm (7.87 in.) away from the ECU and sensors of the ve-
hicle's electronic systems. For details about ECU and sensors locations, refer to the section on
the applicable component.
(3) Avoid winding the antenna feeder together with other wiring as much as possible, and also avoid
running the antenna feeder parallel with other wire harnesses.
(4) Check that the antenna and feeder are correctly adjusted.
(5) Do not install powerful mobile communications system.
4. FOR USING OBD II SCAN TOOL OR TOYOTA HAND-HELD TESTER
CAUTION:
Observe the following items for safety reasons:
Before using the OBD II scan tool or TOYOTA hand-held tester, the OBD II scan tool's instruc-
tion book or TOYOTA hand-held tester's operator manual should be read thoroughly.
Be sure to route all cables securely when driving with the OBD II scan tool or TOYOTA hand-
held tester connected to the vehicle. (i.e. Keep cables away from feet, pedals, steering wheel
and shift lever.)
Two persons are required when test driving with the OBD II scan tool or TOYOTA hand-held
tester, one person to drive the vehicle and the other person to operate the OBD II scan tool or
TOYOTA hand-held tester.

EVALUATION
ProblemPossible cause
If there is no 1 - 2 up-shift. Governor valve is defective
1 - 2 shift valve is stuck
If there is no 2 - 3 up-shift. 1 - 2 shift valve is stuck
If there is no 3 - O/D up-shift
(throttle valve operating less than 86%). 3 - O/D shift valve is stuck
Solenoid valve or circuit defective
If the shift point is defective.
Throttle cable out of adjustment
Throttle valve, 1 - 2 shift valve, 2 - 3 shift valve, 3 - O/D shift valve etc. are
defective
(2) In the same way, check the shock and slip at 1 " 2, 2 " 3 and 3 "O/D up-shifts.
EVALUATION
ProblemPossible cause
If the shock is severe.
Line pressure is too high
Accumulator is defective
Check ball is defective
(3) Run in the 3rd gear or O/D of the D position, check the abnormal noise and vibration.
HINT:
Check for the cause of abnormal noise and vibration must be made with extreme care as they could also
be due to unbalance in the drive shaft, differential, tires and torque converter clutch, etc.
(4) While running in the 3rd gear or O/D of the D position, check that the possible kick-down vehicle
speed limits for the 3 " 1, 3 " 2 and O/D "2 kick-down conform to those indicated in the auto-
matic shift schedule (See page SS-30).
EVALUATION
ProblemPossible cause
If the possible kick-down vehicle speed limit is defective.
Throttle cable out of adjustment
Throttle valve, 1 - 2 shift valve, 2 - 3 shift valve, 3 - O/D shift valve etc. are
defective
(5) Check the abnormal shock and slip at kick-down.
(6) While running at about 60 km/h (37 mph) in the O/D of the D position, release your foot from the
accelerator pedal and shift into the L position. Then check if the 2 "1 down-shift point conforms
to that indicated in the automatic shift schedule (See page SS-30).
(b) Inspect the lock-up mechanism.
(1) Drive in the D position at a steady speed (Lock-up ON) of about 70 km/h (43 mph).
(2) Lightly depress the accelerator pedal and check that the engine speed does not change abruptly.
If there is a big jump in engine RPM, there is no lock-up.
(c) 2 position test.
(1) While running in the 2nd gear of the 2 position, release the accelerator pedal and check the en-
gine braking effect.
EVALUATION
ProblemPossible cause
If these is no engine braking effect. 2nd coast brake is defective.
(2) Check the abnormal noise during acceleration and deceleration.
(3) Check the shock during up-shift and down-shift.
(d) L position test.
(1) While running in the L position, check 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.
