2000 SUZUKI SWIFT CHECK

GENERAL INFORMATION 0A-5
CAUTION:

Even when the accident was light enough not to cause air
bags to deploy, be sure to inspect system parts and other
related parts according to instructions under “Repair and
Inspection Required after an Accident” in Section 9J.

When servicing parts other than air bag system, if shocks
may be applied to air bag system component parts, re-
move those parts beforehand.

When handling the air bag (inflator) modules (driver and
passenger) or SDM, be careful not to drop it or apply an im-
pact to it. If an excessive impact was applied (e.g.,
dropped from a height of 91.4 cm (3 feet) or more), never
attempt disassembly or repair but replace it with a new
one.

When grease, cleaning agent, oil, water, etc. has got onto
air bag (inflator) modules (driver and passenger), wipe off
immediately with a dry cloth.

Air bag wire harness can be identified easily as it is cov-
ered with a yellow protection tube. Be very careful when
handling it.

When an open in air bag wire harness, damaged wire har-
ness, connector or terminal is found, replace wire har-
ness, connectors and terminals as an assembly.

Do not apply power to the air bag system unless all com-
ponents are connected or a diagnostic chart requests it,
as this will set a diagnostic trouble code.

Never use air bag system component parts from another
vehicle.

When using electric welding, be sure to temporarily dis-
able air bag system referring to “Disabling Air Bag Sys-
tem” under “Service Precaution” in Section 9J.

Never expose air bag system component parts directly to
hot air (drying or baking the vehicle after painting) or
flames.

WARNING / CAUTION labels are attached on each part of
air bag system components. Be sure to follow the instruc-
tions.

After vehicle is completely repaired, perform “Air Bag
Diagnostic System Check” described in “Diagnosis” in
Section 9J.

0A-8 GENERAL INFORMATION

When disconnecting vacuum hoses, attach a tag describing
the correct installation positions so that the hoses can be re-
installed correctly.

After servicing fuel, oil, coolant, vacuum, exhaust or brake
systems, check all lines related to the system for leaks.

For vehicles equipped with fuel injection systems, never dis-
connect the fuel line between the fuel pump and injector
without first releasing the fuel pressure, or fuel can be
sprayed out under pressure.

When performing a work that produces a heat exceeding
80C in the vicinity of the electrical parts, remove the heat
sensitive electrical part(s) beforehand.

Use care not to expose connectors and electrical parts to wa-
ter which will be a cause of a trouble.

GENERAL INFORMATION 0A-9

Always be careful not to handle electrical parts (computer,
relay, etc.) in a rough manner or drop them.
PRECAUTIONS FOR CATALYTIC CONVERTER
For vehicles equipped with a catalytic converter, use only un-
leaded gasoline and be careful not to let a large amount of un-
burned gasoline enter the converter or it can be damaged.
–Conduct a spark jump test only when necessary, make it as
short as possible, and do not open the throttle.
–Conduct engine compression checks within the shortest
possible time.
–Avoid situations which can result in engine misfire (e.g.
starting the engine when the fuel tank is nearly empty.).
PRECAUTIONS FOR ELECTRICAL CIRCUIT
SERVICE

When replacing a fuse, make sure to use a fuse of the speci-
fied capacity. Use of a fuse with a larger capacity will cause
a damage to the electrical parts and a fire.

When disconnecting and connecting coupler, make sure to
turn ignition switch OFF, or electronic parts may get dam-
aged.

1. Check for loose connection
Sensor
ECM
0A-12 GENERAL INFORMATION

When checking connection of terminals, check its male half
for bend and female half for excessive opening and both for
locking (looseness), corrosion, dust, etc.

Before measuring voltage to check for electrical system,
check to make sure that battery voltage is 11 V or higher.
Such terminal voltage check at low battery voltage will lead
to erroneous diagnosis.
ELECTRICAL CIRCUIT INSPECTION
PROCEDURE
While there are various electrical circuit inspection methods, de-
scribed here is a general method to check its open and short circuit
by using an ohmmeter and a voltmeter.
OPEN CIRCUIT CHECK
Possible causes for the open circuit are as follows. As the cause is
in the connector or terminal in many cases, they need to be checked
particularly carefully.

Loose connection of connector.

Poor contact of terminal (due to dirt, corrosion or rust on it, poor
contact tension, entry of foreign object etc.).

Wire harness being open.
When checking system circuits including an electronic control unit
such as ECM, TCM, ABS control module, etc., it is important to per-
form 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.

1. Looseness of crimping
2. Open
3. Thin wire (single strand of wire)
Check contact tension by
inserting and removing just
for once
GENERAL INFORMATION 0A-13
3) Using a test male terminal, check both terminals of the circuit be-
ing 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 procedure described in
the following page, check the wire harness for open circuit and
poor connection 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.
2) Disconnect the connector included in the circuit (connector-B in
the figure) and measure resistance between terminals A-1 and
B-1.
If no continuity is indicated, that means that the circuit is open
between terminals A-1 and B-1. If continuity is indicated, there
is an open circuit between terminals B-1 and C-1 or an ab-
normality in connector-B.
Voltage Check
If voltage is supplied to the circuit being checked, voltage check can
be used as circuit check.
1) With all connectors connected and voltage applied to the circuit
being checked, measure voltage between each terminal and
body ground.

1. Other parts
1. To other parts
2 V voltage drop
0A-14 GENERAL INFORMATION
If measurements were taken as shown in the figure at the left and
results were as listed below, it means that the circuit is open be-
tween terminals B-1 and A-1.
Voltage Between:
C-1 and body ground: Approx. 5 V
B-1 and body ground: Approx. 5 V
A-1 and body ground: 0 V
Also, if measured values were as listed below, it means that there
is a resistance (abnormality) of such level that corresponds to the
voltage drop in the circuit between terminals A-1 and B-1.
Voltage Between:
C-1 and body ground: Approx. 5 V
B-1 and body ground: Approx. 5 V
A-1 and body ground: Approx. 3 V
SHORT CIRCUIT CHECK (wire harness to ground)
1) Disconnect negative cable from battery.
2) Disconnect connectors at both ends of the circuit to be checked.
NOTE:
If the circuit to be checked is connected to other parts, dis-
connect all connectors of those parts.
Otherwise, diagnosis will be misled.
3) Measure resistance between terminal at one end of circuit (A-1
terminal in figure) and body ground. If continuity is indicated, it
means that there is a short to ground between terminals A-1 and
C-1 of the circuit.
4) Disconnect the connector included in circuit (connector B) and
measure resistance between A-1 and body ground.
If continuity is indicated, it means that the circuit is shorted to the
ground between terminals A-1 and B-1.

1. Check contact tension by inserting and removing just once
2. Check each terminal for bend and proper alignment
GENERAL INFORMATION 0A-15
INTERMITTENT AND POOR CONNECTION
Most intermittent are caused by faulty electrical connections or wir-
ing, although a sticking relay or solenoid can occasionally be at
fault. When checking it for proper connection, perform careful
check of suspect circuits for:

Poor mating of connector halves, or terminals not fully seated in
the connector body (backed out).

Dirt or corrosion on the terminals. The terminals must be clean
and free of any foreign material which could impede proper termi-
nal contact. However, cleaning the terminal with a sand paper or
the like is prohibited.

Damaged connector body, exposing the terminals to moisture
and dirt, as well as not maintaining proper terminal orientation
with the component or mating connector.

Improperly formed or damaged terminals.
Check each connector terminal in problem circuits carefully to en-
sure good contact tension by using the corresponding mating ter-
minal.
If contact tension is not enough, reform it to increase contact ten-
sion or replace.

Poor terminal-to-wire connection.
Check each wire harness in problem circuits for poor connection
by shaking it by hand lightly. If any abnormal condition is found,
repair or replace.

Wire insulation which is rubbed through, causing an intermittent
short as the bare area touches other wiring or parts of the vehicle.

Wiring broken inside the insulation. This condition could cause
continuity check to show a good circuit, but if only 1 or 2 strands
of a multi-strand-type wire are intact, resistance could be far too
high.
If any abnormality is found, repair or replace.

VEHICLE LIFTING POINTS
WARNING:

Before applying hoist to underbody, always take vehicle balance throughout service into consider-
ation. Vehicle balance on hoist may change depending of 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 trying 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.
