INSPECTION PROCEDURE
NOTICE:
The vehicle is equipped with SRS (Supplemental Restraint System) such as airbags. Before servic-
ing (including removal or installation of parts), be sure to read the precautionary notice for the sup-
plemental restraint system (See page RS±1).
1 Check illumination.
CHECK:
Check if the illumination for the radio and navigation assy, steering pad switch assy or others (A/C switch,
cigarette lighter, etc.) comes on when the light control switch is turned to the HEAD or TAIL position.

9. SUPPLEMENTAL RESTRAINT SYSTEM (SRS)
The SEQUOIA is equipped with an SRS (Supplemental Re-
straint System) such as the driver, passenger, side, curtain
shield airbag. Failure to carry out service operation in the cor-
rect sequence could cause the SRS to unexpectedly deploy
during servicing, possibly leading to a serious accident. Before
servicing (including removal or installation of parts, inspection
or replacement), be sure to read the precautionary notices tn
the RS section.
10. INITIALIZATION
NOTICE:
When disconnecting the battery terminal, initialize the fol-
lowing system after the terminal is reconnected.

PRECAUTION

Care must be taken to replace parts properly because they could affect the performance of the
steering system and result in a driving hazard.

The SEQUOIA is equipped with an SRS (Supplemental Restraint System) such as the driver air-
bag and front passenger airbag. Failure to carry out service operation in the correct sequence
could cause the SRS to unexpectedly deploy during servicing, possibly leading to a serious
accident. Before servicing (including removal or installation of parts, inspection or replace-
ment), be sure to read the notices precautionary in the RS section.

When disconnecting the battery terminal, initialize the following system after the terminal is re-
connected.
System NameSee Page
Back Door Power Window Control SystemBE±77

When replacing the steering angle sensor, drive the vehicle straight ahead at a speed of 6.5 mph
(10.5 km/h) or more. Accordingly, zero point calibration of the steering angle sensor is per-
formed.

After performing ºFront wheel alignment adjustmentº, clearing and reading the yaw rate & de-
celeration sensor zero point calibration data is necessary (See page DI±897).

(d) Turn the steering wheel to its straight position.
HINT:
Refer to the upper surface of the steering wheel, steering spoke
and SRS airbag line for the straight position.
(e) Draw a new line on the masking tape of the steering wheel
as shown in the illustration.
(f) Measure the distance between the 2 lines on the masking
tape of the steering wheel.
(g) Convert the measured distance to steering angle.
Measured distance 1 mm (0.04 in.) = Steering angle
approximately 1 deg.
HINT:
Make a note of the steering angle.
2. ADJUST STEERING ANGLE
(a) Draw a line on the RH and LH tie rod and rack ends where
it can easily be seen.
(b) Using a paper gauge, measure the distance from RH and
LH tie rod ends to the rack end screws.
HINT:

Measure the RH side and LH side.

Make a note of the measured values.
(c) Remove the RH and LH boot clips from the rack boots.
(d) Loosen the RH and LH lock nuts.
(e) Turn the RH and LH rack end by the same amount (but
in different directions) according to the steering angle.
1 turn 360 deg. of rack end (1.5 mm (0.059 in.) horizon-
tal movement) = 12 deg. of steering angle
(f) Tighten the RH and LH lock nuts.
Torque: 55 N´m (560 kgf´cm, 41 ft´lbf)
NOTICE:
Make sure that the difference in length between RH and LH
tie rod ends and rack end screws are within 1.5 mm (0.059
in.).
(g) Install the RH and LH boot clips.
