WARNING: TO AVOID DEPLOYMENT WHEN
TROUBLE-SHOOTING THE SRS SYSTEM, DO NOT
USE ELECTRICAL TEST EQUIPMENT, SUCH AS
BATTERY-POWERED OR A/C-POWERED
VOLT-METER, OHMMETER, ETC., OR ANY TYPE OF
ELECTRICAL EQUIPMENT OTHER THAN
SPECIFIED IN THIS MANUAL. DO NOT USE A
NON-POWERED PROBE-TYPE TESTER.
INSTRUCTION IN THIS MANUAL MUST BE FOL-
LOWED CAREFULLY, OTHERWISE PERSONAL IN-
JURY MAY RESULT.
When servicing a vehicle equipped with Supplemental
Restraint System, pay close attention to all WARNINGS
and CAUTIONS.
For detailed explanation about SRS, refer to Restraints
section.
The steering column has three important features in
addition to the steering function:
1. The column is energy absorbing, designed to
compress in a front-end collision to minimize the
possibility of injury to the driver of the vehicle.
2. The ignition switch and lock are mounted
conveniently on the column.
3. With the column mounted lock, the ignition and
steering operation can be locked to prevent theft of
the vehicle.
The column can be disassembled and reassembled.
However, to ensure the energy absorbing action, use only
the specified screws, bolts and nuts as designated, and
tighten them to the specified torque.
Handle the column with care when it is removed from the
vehicle. A sharp blow on the end of steering shaft or shift
lever, or dropping the assembly could shear or loosen the
fasteners that maintain column rigidity.
Diagnosis
Since the problems in steering, suspension, wheels and
tires involve several systems, they must all be considered
when diagnosing a complaint. To identify the symptom,
always road test the vehicle first. Proceed with the follow-
ing preliminary inspections and correct any defects which
are found.
1. Inspect tires for proper pressure and uneven wear.
2. Raise vehicle on a hoist, then inspect front and rear
suspension and steering linkage for loose or
damaged parts.
3. Spin the front wheels. Inspect for out-of-round tires,
out-of-balance tires, loose and/or rough wheel
bearings.
