FLOW CONTROL VALVE
As the discharge rate of the P/S pump increases in proportion to the
pump revolution speed, a flow control valve is added to control it so
that the optimum amount of fluid for steering operation is supplied
according to the engine speed (driving condition).
Described below is its operation at different engine speed.

REMOVAL
NOTE:
Be sure to clean each joint of suction and discharge sides
thoroughly before removal.
1) Remove suction hose from pump, then disconnect battery nega-
tive cable.
2) Remove P / S fluid reservoir with suction hose.
3) Remove union bolt. Then disconnect high pressure pipe from
pump.
NOTE:

under joints or a plug to pipe.
4) Disconnect pressure switch lead wire at switch terminal.
5) Loosen related bolts and remove power steering drive belt.
6) Remove P / S pump mounting bolt (s).
7) Remove P / S pump.
NOTE:
Plug each port of removed pump to prevent dust or any oth-
er foreign matter from entering.
DISASSEMBLY
1) Clean its exterior thoroughly.
2) With aluminum plates placed on vise first, grip pump body with
it.
3) Remove suction connector bolt, suction connector and O-ring
from pump body.
4) Remove power steering pressure switch (terminal set) from
pump body.
5) Remove plug, flow control spring and relief valve (flow control
valve) from pump body.
6) Remove cover bolts, pump cover and O-ring from pump body.
7) Remove snap ring from pump shaft.
8) Remove vanes from rotor.
9) Remove cam ring, rotor, side plate and O-rings from pump
body.

3C1-2 AIR BAG STEERING WHEEL AND COLUMN
GENERAL DESCRIPTION
This double tube type steering column has the following three important features in addition to the steering function:

The column is energy absorbing, designed to compress in a front-end collision.

The ignition switch and lock are mounted conveniently on this column.

With the column mounted lock, the ignition and steering operations can be locked to inhibit theft of the vehicle.
To insure the energy absorbing action, it is important that only the specified screws, bolts, and nuts be used as
designated and that they are tightened to the specified torque. When the column assembly is removed from the
vehicle, special care must be taken in handling it. Use of a steering wheel puller other than the one recommended
in this manual or a sharp blow on the end of the steering shaft, leaning on the assembly, or dropping the assembly
could shear the plastic shear pins which maintain column length and position.
The driver air bag (inflator) module is one of the supplemental restraint (air bag) system components and is
mounted to the center of the steering wheel. During certain frontal crashes, the air bag system supplements the
restraint of the driver's and passenger's seat belts by deploying the air bags. The air bag (inflator) module should
be handled with care to prevent accidental deployment. When servicing, be sure to observe all WARNINGS in this
section. Refer to ªSERVICE PRECAUTIONSº in Section 10B.

INSPECTION
WARNING:
Never disassemble air bag (inflator) module or measure its
resistance. Otherwise, personal injury may result.
CAUTION:
If air bag (inflator) module was dropped from a height of
90 cm (3 ft) or more, it should be replaced.
Check air bag (inflator) module visually and if any of the following
is found, replace it with a new one.

Air bag being deployed.

Trim cover (pad surface) being cracked.

Wire harness or connector being damaged.

Air bag (inflator) module being damaged or having been exposed
to strong impact (dropped).
INSTALLATION
1) Connect horn connector securely.
2) Connect yellow connector of driver air bag (inflator) module con-
nector as shown in the figure securely.
ii) Connect connector.
ii) Lock connector with lock lever.
3) Install horn connector and driver air bag (inflator) module con-
nector.
4) Install driver air bag (inflator) module to steering wheel, taking
care so that no part of wire harness is caught between them.
5) Make sure that clearance between module and steering wheel
is uniform all the way.
6) Tighten driver air bag (inflator) module mounting bolt (left side)
to specified torque first and then driver air bag (inflator) module
mounting bolt (right side) to specified torque.
Tightening Torque
(a): 9 N
.m (0.9 kg-m, 6.5 lb-ft)
7) Connect negative battery cable.
8) Enable air bag system. Refer to ªENABLING AIR BAG SYS-
TEMº under ªSERVICE PRECAUTIONSº in Section 10B.

INSTALLATION
1) Check that vehicle's front tires are at straight-ahead position and
contact coil is centered. Refer to ªCENTERING CONTACT
COILº in this section.
CAUTION:
These two conditions are prerequisite for installation of
steering wheel. If steering wheel has been installed with-
out these conditions, contact coil will break when steer-
ing wheel is turned.
2) Install steering wheel to steering shaft with 2 lugs on contact coil
fitted in two grooves in the back of steering wheel and also align-
ing marks on steering wheel and steering shaft.
3) Tighten steering shaft nut to specified torque.
Tightening Torque
(a): 33 N
.m (3.3 kg-m, 23.5 lb-ft)
4) Install driver air bag (inflator) module to steering wheel. Refer to
ªDRIVER AIR BAG (INFLATOR) MODULEº in this section.
CONTACT COIL AND COMBINATION SWITCH
ASSEMBLY
CAUTION:
Do not turn contact coil (on combination switch) more than
allowable number of turns (about two and a half turns from
the center position clockwise or counterclockwise respec-
tively), or coil will break.
REMOVAL
1) Remove steering wheel from steering column. Refer to
ªSTEERING WHEELº in this section.
2) Remove steering column hole cover.
3) Remove steering column cover screws (3 pieces).
4) Separate upper cover and lower cover, then remove them.
5) Disconnect all connectors for contact coil and combination
switch assembly.

INSPECTION
Check to make sure that the following:

Steering column moves smoothly when adjustable steering col-
umn release lever is at lower position (i.e., steering column is not
locked).

Steering column is fixed securely when adjustable steering col-
umn release lever is at upper position (i.e., steering column is
locked).
