ABS SUZUKI SWIFT 2000 1.G RG413 Service Workshop Manual

0A-14 GENERAL INFORMATION
When checking system circuits including an electronic control unit
such as ECM, TCM, ABS control module, etc., it is important to
perform careful check, starting with items which are easier to
check.
1) Disconnect negative (–) cable from battery
2) Check each connector at both ends of the circuit being
checked for loose connection. Also check lock condition of
connector if equipped with connector lock.
3) Using a test male terminal, check both terminals of the circuit
being checked for contact tension of its female terminal.
Check each terminal visually for poor contact (possibly
caused by dirt, corrosion, rust entry of foreign object, etc.).
At the same time, check to make sure that each terminal is
locked in the connector fully.
4) Using continuity check or voltage check the following proce-
dure, check the wire harness for open circuit and poor con-
nection with its terminals. Locate abnormality, if any.
CONTINUITY CHECK
1) Measure resistance between connector terminals at both
ends of the circuit being checked (between A-1 and C-1 in
the figure). If no continuity is indicated (infinity or over limit),
that means that the circuit is open between terminals A-1
and C-1.
1. Check contact tension by inserting and removing just for once.
1. Looseness of crimping
2. Open
3. Thin wire (single strand of wire)

0A-20 GENERAL INFORMATION
VEHICLE LIFTING POINTS
WHEN USING FRAME CONTACT HOIST
WARNING:
 Before applying hoist to underbody, always take vehicle balance throughout service into consider-
ation. Vehicle balance on hoist may change depending on what part to be removed.
 Before lifting up the vehicle, check to be sure that end of hoist arm is not in contact with brake pipe,
fuel pipe, bracket or any other part.
 When using frame contact hoist, apply hoist as shown (right and left at the same position). Lift up
the vehicle till 4 tires are a little off the ground and make sure that the vehicle will not fall off by try-
ing to move vehicle body in both ways. Work can be started only after this confirmation.
 Make absolutely sure to lock hoist after vehicle is hoisted up.

MAINTENANCE AND LUBRICATION 0B-15
WHEEL DISCS INSPECTION
Inspect each wheel disc for dents, distortion and cracks. A disc in
badly damaged condition must be replaced.
WHEEL BEARING INSPECTION
1) Check front wheel bearing for wear, damage, abnormal
noise or rattles. For details, refer to “WHEEL DISC, NUT
AND BEARING CHECK” in Section 3D.
2) Check rear wheel bearing for wear, damage, abnormal noise
or rattles. For details, refer to “WHEEL DISC, NUT AND
BEARING CHECK” in Section 3E.
SUSPENSION SYSTEM
INSPECTION
Inspect front struts & rear shock absorbers for evidence of oil
leakage, dents or any other damage on sleeves ; and
inspect anchor ends for deterioration.
Replace defective parts, if any.
Check front and rear suspension systems for damaged,
loose or missing parts ; also for parts showing signs of wear
or lack of lubrication.
Repair or replace defective parts, if any.
Check front suspension arm ball joint stud dust seals for
leakage, detachment, tear or any other damage.
Replace defective boot, if any.
STEERING SYSTEM
INSPECTION
1) Check steering wheel for play and rattle, holding vehicle
straight on ground.
Steering wheel play
“a” : 0 – 30 mm (0 – 1.1 in.)
2) Check bolts and nuts for tightness and retighten them as
necessary. Repair or replace defective parts, if any.

3-2 STEERING, SUSPENSION, WHEELS AND TIRES
DIAGNOSIS
GENERAL DIAGNOSIS
Since the problems in steering, suspension, wheels and tires involve several systems, they must all be consid-
ered when diagnosing a complaint. To avoid using the wrong symptom, always road test the vehicle first. Pro-
ceed with the following preliminary inspection and correct any defects which are found.
1) Inspect tires for proper pressure and uneven wear.
2) Raise vehicle on a hoist and inspect front and rear suspension and 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.

3C-2 STEERING WHEEL AND COLUMN
GENERAL DESCRIPTION
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 vehi-
cle.
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 col-
umn length and position.
STEERING WHEEL AND DRIVER AIR BAG (INFLATOR) MODULE
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 and CAUTIONS and “SERVICE PRECAUTIONS” under “ON-VEHICLE SER-
VICE” in Section 10B.
DIAGNOSIS
For maintenance service of the steering wheel and column, refer to Section 0B.
For diagnosis of the steering wheel and column, refer to Section 3.
For diagnosis of the air bag system, refer to Section 10B.
INSPECTION AND REPAIR REQUIRED AFTER ACCIDENT
After an accident, whether the air bag has been deployed or not, be sure to perform checks, inspections and
repairs described under “CHECKING STEERING COLUMN ASSEMBLY AND LOWER SHAFT FOR ACCI-
DENT DAMAGE” as well as “REPAIRS AND INSPECTIONS REQUIRED AFTER ACCIDENT” under “DIAGNO-
SIS” in Section 10B.
