TORQUE CONVERTER CLUTCH
AND DRIVE PLATE
INSPECTION
1. INSPECT ONE±WAY CLUTCH
(a) Install SST so that it fits in the notch of the converter hub
and outer race of the one±way clutch.
SST 09350±30020 (09351±32020)
(b) Press on the serrations of the stator with a finger and ro-
tate it.
(c) Check if it rotates smoothly when turned clockwise and
locks when turned counterclockwise.
If necessary, clean the converter clutch and retest the one±way
clutch.
Replace the converter clutch if the clutch still fails the test.
2. MEASURE DRIVE PLATE RUNOUT AND INSPECT
RING GEAR
(a) Set up a dial indicator and measure the drive plate runout.
Maximum runout: 0.20 mm (0.0079 in.)
(b) Check for damage to the ring gear.
If runout is not within the specification or if the ring gear is dam-
aged, replace the drive plate. If installing a new drive plate, note
the orientation of the spacers and tighten the bolts (See page
EM±83 or EM±95).

(d) Discharge Warning Light
This light warns that the battery is being
discharged.
If it comes on while you are driving, there
is a problem somewhere in the charging
system.
The engine ignition will continue to oper-
ate, however, until the battery is dis-
charged. Turn off the air conditioning,
blower, radio, etc., and drive directly to
the nearest Toyota dealer or repair shop.
NOTICE
Do not continue driving if the engine
drive belt is broken or loose.
(e) Malfunction Indicator Lamp
This lamp comes on when the ignition
key is turned to the ªONº position and
goes off after the engine starts. This
means that the warning light system is
operating properly.
If the lamp remains on or the lamp
comes on while driving, first check the
followings.

Empty fuel tank
If the fuel tank is empty, refuel immedi-
ately.

Loose fuel tank cap
If the fuel tank cap is loose, securely
tighten it.
These cases are temporary malfunctions.
The malfunction indicator lamp will go off
after taking several driving trips.
If the lamp does not go off even after
several trips, contact your Toyota dealer
as soon as possible.
If the fuel tank is not empty or the fuel
tank cap is not loose...

There is a problem somewhere in the
engine, emission control system, elec-
tronic throttle control system, automatic
transmission electrical system or warn-
ing light system itself.
Contact your Toyota dealer as soon as
possible to service the vehicle.
If engine speed does not increase when
the accelerator pedal is depressed, there
may be a problem somewhere in the elec-
tronic throttle control system.
At this time, vibration may occur. Howev-
er, if you depress the accelerator pedal
more firmly and slowly, you can drive your
vehicle at low speeds. Have your vehicle
checked by your Toyota dealer as soon as
possible.Even if the abnormality of the electronic
throttle control system is corrected during
low speed driving, the system may not be
recovered until the engine is stopped and
the ignition key is turned to ªACCº or
ªLOCKº position.
CAUTION
Be especially careful to prevent erro-
neous pedal operation.
Emissions inspection and maintenance
(I/M) programs
We recommend you to contact your
Toyota dealer to check your vehicle's
emission control system and OBD
(On±Board Diagnostics) system before
taking your vehicle for a state emission
inspection.
For details, see ªEmissions Inspection and
Maintenance (I/M) programsº on page 416
in Section 6.
