WARNING:
For vehicles equipped with Supplemental Restraint (Airbag) System:
• Service on and around the a irbag system components or wiring must be performed only by
an au tho ris ed HO LDE N ret ail er. P leas e obs erv e all WA RNIN G S and SE RVI CE PR EC AUTI ONS
refer to Se ction 1 0B AIRBAG SYST EM, ON-VE HICLE SE RVICE befo re performing s ervice on
or around t he airbag system components or wiring. Failure to follow WARNINGS could result
in unintentional activation of the system or could render the system inoperative. Either of
these two conditions may result in severe injury.
• The procedures in this section must be followed in the order listed to temporarily disable the
airbag system an d preve nt fal se diagnost ic codes f rom setting. Failure to follow p roced ures
could result in possible airbag system activation, personal injury or otherwise unneeded air-
bag system repairs.
CAUTION:
When fastene rs are rem ov ed, always reins tall them at the same lo cation from which th ey were
removed. If a fastener needs to be replaced, use the correct part number fastener for that appli-
cation. If the correct part number fastener is not available, a fas tener of equal size and strength
(or stronger) may be used. Fasteners that are not reused, and those requiring thread-locking
compound, will be c alled o ut. T he c orre ct torque value must be u s ed w he n ins tallin g faste ne rs

1. GENERAL DESCRIPTION
1.1 STEERING COLUMN
This double tube type steering column has 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 steer-
ing shaft, leaning on the assembly, or dropping the assembly could shear the plastic shear pins which main-
tain column length and position.
1.2 STEERING WHEEL AND DRIVER AIRBAG (INFLATOR) MODULE
• The driver airbag (inflator) module is one of the supplemental restraint (airbag) system components and is
mounted to the centre of the steering wheel. During certain front end crashes, the airbag system supple-
ments the restraint of the driver’s and passenger’s seat belts by deploying the airbags.
• The airbag (inflator) module should be handled with care to prevent accidental deployment. When servic-
ing, be sure to observe all WARNINGS and CAUTIONS and SERVICE PRECAUTIONS, refer to
Section 10B, 3 ON-VEHICLE SERVICE.
2. DIAGNOSIS
For maintenance service of the steering wheel and column, refer to Section 0B GENERAL INFORMATION.
For diagnosis of the steering wheel and column, refer to Section 3 STEERING, SUSPENSION, WHEELS
AND TYRES.
For diagnosis of the airbag system, refer to Section 10B AIRBAG SYSTEM.
2.1 INSPECTION AND REPAIR REQUIRED AFTER ACCIDENT
After an accident, w hether the a irbag has been d eployed or no t, be sure to perfor m che cks, inspect ions and
repairs, refer to 3.9 CHECKING STEERING COLUMN ASSEMBLY AND LOWER SHAFT FOR ACCIDENT
DAMAGE in this Section, also refer to Section 10B, 3.2 REPAIRS AND INSPECTIONS REQUIRED AFTER A
