8) If equipped with shift (key) interlock cable, remove shift (key) in-
terlock cable screw and then disconnect its cable from ignition
switch.
9) Remove steering column from vehicle.
INSPECTION
NOTE:
Vehicles involved in accidents resulting in body damage,
where steering column has been impacted or air bag
deployed, may have a damaged or misaligned steering col-
umn.
CHECKING PROCEDURE
1) Check that two capsules are attached to steering column brack-
et securely. Check clearance between capsules and steering
column bracket. Clearance should be 0 mm (0 in.) on both sides.
If found loose or clearance, replace steering column assembly.
2) Check two plates for any damages such as crack or breakage.
If anything is found faulty, replace as steering column assembly.
3) Take measurement ªaº as shown. If it is shorter than specified
length, replace column assembly with new one.

4) Check steering column lower seal for breakage or deformation.
If found defective, replace.
5) Check steering shaft joints and shaft for any damages such as
crack, breakage, malfunction or excessive play.
If anything is found faulty, replace as steering shaft lower assem-
bly or steering column assembly.
6) Check steering shaft for smooth rotation.
If found defective, replace as column assembly.
7) Check steering shaft and column for bend, cracks or deforma-
tion.
