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 stater with a finger and rotate
it.
Check if it rotates smoothly when turned clockwise and
locks up when turned counterclockwise.
2. MEASURE DRIVE PLATE RUNOUT AND INSPECT
RING GEAR
Set up a dial indicator and measure the drive plate runout.
Maximum runout: 0.20 mm (0.0079 in.)
If runout exceeds 0.20 mm (0.0079 in.) or if the ring gear is dam-
aged, replace the drive plate. If installing a new drive plate, note
the orientation of spacers and tighten the bolts.
Torque: 83 N´m (850 kgf´cm, 61 ft´lbf)
3. MEASURE TORQUE CONVERTER CLUTCH SLEEVE
RUNOUT
(a) Temporarily mount the torque converter clutch to the drive
plate. Set up a dial indictor.
Maximum runout: 0.30 mm (0.0118 in.)
If runout exceeds 0.30 mm (0.0118 in.), try to correct by reori-
enting the installation of the torque converter clutch.
If excessive runout cannot be corrected, replace the torque
converter clutch.
HINT:
Mark the position of the torque converter clutch to ensure cor-
rect installation.
(b) Remove the torque converter clutch.

10. SET NO.1 CYLINDER TO APPROX. 60°/ BTDC COM-
PRESSION
(a) Turn the crankshaft pulley, and align its groove with timing
mark º0º of the No.1 timing belt cover.
NOTICE:
Always turn the crankshaft clockwise.
(b) Check that the timing marks (TDC mark) of the camshaft
timing pulleys are aligned with the timing marks of the
No.4 timing belt cover.
If not, turn the crankshaft 1 revolution (360°).
(c) Turn the crankshaft pulley 60° counterclockwise to place
the sub timing mark (60° mark BTDC) on the crankshaft
pulley at the timing mark º0º position of the No.1 timing
belt cover.
NOTICE:
If the timing belt is disengaged, having the crankshaft
pulley at the wrong angle can cause the piston head and
valve head to come into contact with each other when you
remove the camshaft timing pulleys (steps 11 to 17), thus
resulting damage. So, always set the crankshaft pulley at
the correct angle.
(d) Check that the dot marks (60° mark BTDC) of the cam-
shaft timing pulleys are aligned with the timing marks of
the No.4 timing belt cover.
(e) Remove the crankshaft pulley bolt.
NOTICE:
Do not turn the crankshaft pulley.

NOTICE:
Always turn the crankshaft clockwise.
(b) Check that the timing marks of the camshaft timing pul-
leys are aligned with the timing marks of the No.4 timing
belt cover.
If not, turn the crankshaft 1 revolution (360°).
11. INSPECT VALVE CLEARANCE
(a) Check only those valves indicated in the illustration.

Using a feeler gauge, measure the clearance be-
tween the valve lifter and camshaft.

Record the valve clearance measurements of those
that are out of specification. They will be used later
to determine the required replacement adjusting
shim.
Valve clearance (Cold):
Intake0.15 ± 0.25 mm(0.006 ± 0.010 in.)
Exhaust0.25 ± 0.35 mm (0.010 ± 0.014 in.)
(b) Turn the crankshaft pulley 1 revolution (360°), and align
the groove with the timing mark º0º of the No.1 timing belt
cover.

FOR ALL OF VEHICLES
PRECAUTION
1. FOR VEHICLES EQUIPPED WITH SRS AIRBAG AND
SEAT BELT PRETENSIONER
(a) The LEXUS GS400/GS300 is equipped with an SRS
(Supplemental Restraint System), such as the driver air-
bag, front passenger airbag assembly, side airbag as-
sembly and seat belt pretensioners.
Failure to carry out service operations in the correct se-
quence could cause the supplemental restraint system to
unexpectedly deploy during servicing, possibly leading to
a serious accident.
Further, if a mistake is made in servicing the supplemental
restraint system, it is possible the SRS may fail to operate
when required. Before servicing (including removal or
installation of parts, inspection or replacement), be sure
to read the following items carefully, then follow the cor-
rect procedure described in this manual.
(b) GENERAL NOTICE
(1) Malfunction symptoms of the supplemental re-
straint system are difficult to confirm, so the diag-
nostic trouble codes become the most important
source of information when troubleshooting. When
troubleshooting the supplemental restraint system,
always inspect the diagnostic trouble codes before
disconnecting the battery (See page DI±552).
(2) Work must be started after 90 seconds from the
time the ignition switch is turned to the ºLOCKº posi-
tion and the negative (±) terminal cable is discon-
nected from the battery.
(The supplemental restraint system is equipped
with a back±up power source so that if work is
started within 90 seconds of disconnecting the neg-
ative (±) terminal cable from the battery, the SRS
may deploy.)
When the negative (±) terminal cable is discon-
nected from the battery, memory of the clock and
audio systems will be cancelled. So before starting
work, make a record of the contents memorized by
the each memory system. Then when work is fin-
ished, reset the clock and audio systems as before.
This vehicle has power tilt and power telescopic
steering, power seat and power outside rear view
mirror, which are all equipped with memory function,
it is not possible to make a record of the memory
contents. So when the work is finished, therefore it
will be necessary to explain this fact to the custom-
er, and ask the customer to adjust the features and

REPLACEMENT
NOTICE:

To prevent deterioration, do not shock the throttle
position sensor and accelerator pedal position sen-
sor.

Mixing of the foreign objects may cause the gear lock-
ing, so thoroughly check that there is no stuck of any
foreign objects and clean up if any.
1. REPLACE THROTTLE POSITION SENSOR
(a) Remove the 2 set screws and throttle position sensor.
(b) Reinstall the throttle position sensor.
(1) Check that the throttle valve is under the condition
of the opener opening angle (about 3.5°).
(2) Install the sensor to the place where is at 30° ro-
tated to the right from the specified installation posi-
tion.
(3) Gradually turn sensor counterclockwise until it
touches the throttle valve shaft and temporarily
torque the 2 set screws.
(c) Adjust the throttle position sensor.
(1) Connect the throttle position sensor connector.
NOTICE:
At this time, do not connect the throttle control motor con-
nector.
(2) Connect the LEXUS hand±held tester or OBDII
scan tool to the DLC3.
(3) Turn the ignition switch ON.
NOTICE:
After turning the ignition switch ON, do not depress the ac-
celerator pedal.
(4) While reading the value of the throttle valve opening
percentage (THROTTLE POS) of the CURRENT
DATA, turn the throttle position sensor slowly to left
and set the sensor at the center value of the stan-
dard value, and then torque the screws.
Torque: 1.7 N´m (17.5 kgf´cm, 15 in.´lbf)
Standard throttle valve opening percentage:
14.8 ± 0.8 %

12. CENTER SPIRAL CABLE
(a) Check that the front wheels are facing straight ahead.
(b) Turn the cable counterclockwise by hand until it becomes
harder to turn the cable.
(c) Then rotate the cable clockwise about 3 turns to align the
mark.
HINT:
The cable will rotate about 3 turns to either left or right of the
center.
13. INSTALL STEERING WHEEL
(a) Align the matchmarks on the wheel and main shaft.
(b) Torque the wheel set nut.
Torque: 35 N´m (360 kgf´cm, 26 ft´lbf)
(c) Connect the connector.
14. INSTALL STEERING WHEEL PAD
NOTICE:

Make sure the wheel pad is installed to the specified
torque.

If the wheel pad has been dropped, or there are
cracks, dents or other defects in the case or connec-
tor, replace the wheel pad with a new one.

When installing the wheel pad, take care that the wir-
ings do not interfere with other parts and are not
pinched between other parts.
(a) Connect the airbag connector.
(b) Install the pad after confirming that the circumference
groove of the torx screw is caught on the screw case.
(c) Using a torx socket wrench, torque the 2 screws.
Torque: 8.8 N´m (90 kgf´cm, 78 in.´lbf)
(d) Install the steering wheel lower No.2 and No.3 covers.
