STEERING LOWER SHAFT ASSEMBLY
CAUTION:
Never turn steering wheel while steering lower shaft assem-
bly is removed.
Should it have been turned and contact coil (on combina-
tion switch) have got out of its centered position, it needs
to be centered again. Also, turning steering wheel more
than about two and a half turns will break contact coil.
REMOVAL
1) Turn steering wheel so that vehicle's front tires are at straight-
ahead position.
2) Turn ignition switch to ªLOCKº position and remove key.
3) After removing bolt on column side of shaft joint and loosening
bolt on its lower shaft assembly side, move shaft joint to lower
shaft assembly side (in arrow direction in figure).
4) Remove lower shaft assembly lower joint bolt and then remove
lower shaft assembly.
5) Remove shaft joint bolt (lower shaft assembly side) from shaft
joint and then remove shaft joint from lower shaft assembly.

BRAKE INTERLOCK SYSTEM
SHIFT LOCK SOLENOID CONTROL
This system consists of shift lock solenoid control system and inter-
lock cable control system.
The shift lock solenoid control system is so designed that the selec-
tor lever can not be shifted from ªPº range position unless the igni-
tion switch is turned ON and the brake pedal is depressed. And the
interlock cable control system is so designed that the selector lever
cannot be shifted from ªPº range position unless the ignition switch
is turned to ªACCº or ªONº position. Also, the ignition key cannot be
pulled out of the key slot unless the selector lever is in ªPº range.
SHIFT LOCK SOLENOID CONTROL OPERATIONS
When the select lever is in ªPº range, the ignition key position is
ªONº and depressing the brake pedal cause the electric current to
flow to the solenoid. As the shift lock solenoid rod (or the lock plate)
is drawn toward the solenoid in this state, it frees the interlock cam
(or the detent pin), which then allows the select lever to be shifted
from ªPº range to any other position.
Even when the select lever is in ªPº range, if the ignition key position
is ªLOCKº or ªACCº or the brake pedal is not depressed, the electric
current does not flow to the solenoid.
In this state, the shift lock solenoid rod (or the lock plate) is pushed
away from the solenoid by spring force and it obstructs the interlock
cam (or the detent pin) movement. Thus the select lever button
does not work even when pressed and the select lever shift is pre-
vented.

SHIFT LOCK (SOLENOID) MANUAL RELEASE
Shift lock can be manually released by following procedure.
1) Remove access hole cover by unfastening screw.
2) Turn ignition key to ªACCº position and move shift lock solenoid
rod (or manual release plate) toward rear side of vehicle by using
screw driver or the like.
3) In this state, select lever can be moved to any range or position.
SYSTEM INSPECTION
1) Check to make sure that select lever cannot be moved to any
other range from ªPº range position when ignition switch key is
at ªACCº position, at ªLOCKº position (or it is removed from key-
hole of ignition switch) or brake pedal is not depressed.
2) Shift select lever to ªPº range position, release knob button and
check for the following.

Ignition key can be turned between ªLOCKº and ªACCº posi-
tions back and forth and also it can be removed from ignition
switch.

With shift lock solenoid rod (or manual release plate) moved
in arrow direction and ignition key turned to ªACCº position, se-
lect lever can be shifted from ªPº range position to any other
range.

With shift lock solenoid rod (or manual release plate) moved
in arrow direction and ignition key turned to ªLOCKº position,
select lever can not be shifted from ªPº range position to any
other range.

When ignition switch is turned ªONº and brake pedal is de-
pressed, select lever can be shifted from ªPº range position to
any other range.
3) With select lever shifted to any position other than ªPº range,
check that ignition key cannot be turned ªLOCKº position and it
cannot be removed from ignition switch unless it is at ªLOCKº
position.
