WARNING
1.
If the vehicle continues to be driven after the colli-
sion absorbing mechanism has operated, the
steering column shaft may be damaged while it is
in use.
2.
If there is a slack in the mounting base, do not
attempt to repair it but replace the steering column
shaft assembly.
If a collision accident occurs or severe impact is applied on the
steering wheel, the collision energy absorbing mechanism may
have operated. Once the mechanism has operated, it will be
inoperative even it has suffered no apparent damage. Deter-
mine if the steering column shaft can be reused by the following
procedure. If the collision energy absorbing mechanism has
already operated, replace the steering shaft assembly. If any
excessive radial freeplay on the steering wheel is found with
the tilt lever in the lock position, always inspect the steering
shaft assembly.
.
Inspection procedure
1. Remove the lower and upper column covers.
CAUTION
After inspection, do not release the tilt lever until the steer-
ing shaft assembly has been installed.
2. Ensure that the tilt lever is in the lock position.
3. Loosen the two upper steering column mounting bolts by
two turns.
4. Hold the one-way capsules as shown, and then try to rock
them. If there is a slack in either of the capsules, replace the
steering column shaft assembly.
Reference
The mounting base is fixed to the column bracket with the
resin pin. Before the collision energy absorbing mechanism
operates, the column bracket is secured to the mounting
base. After operation, the resin pin will break off causing a
slack.
CAUTION
1. Be careful that nothing is pinched between the mount-
ing base and the body.
2. After inspection, do not release the tilt lever until the
steering shaft assembly has been installed.
5. After inspection, if there is no fault, tighten the two steering
column upper side mounting bolts (2 bolts) to the specified
torque.
Tightening torque: 22
± 4 N⋅m (16 ± 3 ft-lb)
