INSTALLATION
1. CHECK TORQUE CONVERTER CLUTCH INSTALLA-
TION
Using a scale and a straight edge, measure the distance from
the installed surface to the transaxle housing.
Correct distance: 13.7 mm (0.539 in.) or more
2. TRANSAXLE INSTALLATION
Installation is in the reverse order of removal (See page
AX-35).
HINT:
After installation, check and inspect the following items.
Fill ATF and check fluid level (See page DI-160).
Check front wheel alignment (See page SA-4).
Do the road test (See page DI-160).
Adjust the hood (See page BO-6).
NOTICE:
w/ VSC:
After installation, perform the steering angle sensor zero
point calibration (See page DI-252).

(b) In case of using TOYOTA hand-held tester:
Check the sensor signal.
(1) Hook up the TOYOTA hand- held tester to the
DLC3.
(2) Do step (3) - (6) on the previous page.
(3) Read the DTC by following the prompts on the tes-
ter screen.

3. STEERING ANGLE SENSOR ZERO POINT CALIBRA-
TION
NOTICE:
Make sure to perform steering angle sensor zero point cal-
ibration when:
Replacing the steering angle sensor or ECU.
Adjusting the front wheel alignment of the steering
wheel center point in accordance with removal and
installation or replacement of the suspension, axle or
steering parts.
(a) Using the SST, connect terminals Ts and E
1 of DLC1 or
Ts and CG of DLC3
.
SST DLC1: 09843-18020
DLC3: 09843-18040
(b) Turn the ignition switch to the ON position, without start-
ing the engine.
(c) Make sure the steering wheel off center angle is within 3
degrees of center before attempting calibration.

TEM
NOTICE:
When replacing the steering angle sensor or ECU, or
when adjusting the front wheel alignment or steering
wheel center point in accordance with the removing
and installing or replacing the suspension, axle, or
steering parts, make sure to perform the steering
angle sensor zero point calibration (See page
DI-252).
Do not remove or install the VSC related parts unless
necessary. Otherwise, there is a possibility that the
setting of the VSC to be affected.
When working on the VSC related operation, make
sure to check that the preparations before and after
work are completed according to the following
instruction.
When using a drum tester such as a speedometer tes-
ter or chassis dynamometer, etc., or jacking up the
front wheels and driving the wheels, always push in
the TRAC & VSC cut (ºVSC OFFº) switch and turn the
TRAC & VSC system OFF.
(a) Press the VSC OFF switch.
(b) Check that the VSC OFF indicator light comes ON.
HINT:
The VSC OFF indicator light should be always OFF when the
engine is restarted.
(c) Begin measurements.
(d) Press the VSC OFF switch again to change the TRAC &
VSC system to operational condition and check that the
VSC OFF indicator light goes off.
HINT:
The SLIP indicator light blinks when the TRAC system is
operational.
The SLIP indicator light blinks and the VSC buzzer
sounds when the VSC system is operational.
