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.

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.
