INSPECTION
1. Vehicle not involved in collision:
INSPECT SUPPLEMENTAL RESTRAINT SYSTEM
(a) Do a diagnostic system check (See page DI-692).
(b) Do a visual check which includes the following item with
the steering wheel pad (with airbag) installed in the ve-
hicle.
Check cuts, minute cracks or marked discoloration on the
steering wheel pad top surface and in the grooved por-
tion.
2. Vehicle involved in collision and airbag is not
deployed:
INSPECT SUPPLEMENTAL RESTRAINT SYSTEM
(a) Do a diagnostic system check (See page DI-692).
(b) Do a visual check which includes the following items with
the steering wheel pad (with airbag) removed from the ve-
hicle.
Check cuts, minute cracks or marked discoloration
on the steering wheel pad top surface and in the
grooved portion.
Check cuts and cracks in wire harness, and chip-
ping in connectors.
Check the deformation of the horn button contact
plate on the steering wheel pad (with airbag).
CAUTION:
For removal and installation of the steering wheel pad, see
page SR-14 and SR-24, and be sure to follow the correct
procedure.
HINT:
If the horn button contact plate of the steering wheel pad
(with airbag) is deformed, never repair it. Always replace
the steering wheel assembly with a new one.
There should be no interference between the steering
wheel pad and steering wheel, and the clearance should
be uniform all the way around when the new steering
wheel pad is installed on the steering wheel.

3. Vehicle involved in collision and airbag is deployed:
INSPECT SUPPLEMENTAL RESTRAINT SYSTEM
(a) Do a diagnostic system check (See page DI-692).
(b) Do a visual check which includes the following items with
the steering wheel pad (with airbag) removed from the ve-
hicle.
Check that the metal part where the steering wheel
pad is to be installed is not deformed.
Check the damage on the spiral cable connector
and wire harness.
HINT:
Do not repair the metal part where the steering wheel pad
is to be installed even if any deformation is found. Always
replace the steering wheel assembly with a new one.
There should be no interference between the steering
wheel pad and steering wheel, and the clearance should
be uniform all the way around when the new steering
wheel pad is installed on the steering wheel.

STEERING SYSTEM
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 LAND CRUISER is equipped with SRS (Supplemental Restraint System) such as the driver
airbag and front passenger airbag. Failure to carry out service operation in the correct se-
quence 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 re-
placement), be sure to read the precautionary notices in the RS section.

(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 illustraion.
(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.
(h) Perform the zero point calibration of yaw rate and decel-
eration sensors (See page DI-505).
