Steering Symptom Diagnosis
S6JB0B6104001
Since the problems in steering involve several systems, they must all be considered when diagnosing a complaint. To
avoid using the wrong symptom, always road test the vehicle first.
Proceed with the following preliminary inspections and correct any defects which are found.
1) Inspect tires for proper pressure and uneven wear.
2) Raise vehicle on a hoist and inspect steering system for loose or damaged parts.
3) Spin front wheels. Inspect for out-of-round tires, out-of-balance tires, bent rims, loosen and/or rough wheel
bearings.

General Description
Steering Wheel and Column Construction
S6JB0B6201001
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 (6) is removed from the
vehicle, special care must be taken in handling it. Use of a steering wheel puller 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 (1). 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 “Precautions on Service and Diagnosis of
Air Bag System in Section 8B”.

Repair Instructions
Checking Steering Column for Accident
Damage
S6JB0B6206001
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 column.
• Check that 2 capsules (1) are attached to steering
column bracket (2) 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.
• Check two rivets (1) of steering column assembly for
loose, crack and breakage. If found loose, crack and
breakage, replace steering column assembly with
new one.
• Take measurement “a” and “b” as shown in the figure.
If it is shorter than specified length, replace column
assembly with a new one.
