2000 SUZUKI SWIFT engine

4B-2 PROPELLER SHAFTS
PROPELLER SHAFT JOINT CHECK
If universal joints are suspected of producing chattering or rattling
noise, inspect them for wear. Check to see if cross spider rattles
in yokes or if splines are worn down and replace defective propel-
ler shaft with new one.
Noise coming from universal joint can be easily distinguished
from other noises because rhythm of chattering or rattling is in
step with cruising speed. Noise is pronounced particularly on
standing start or in coasting condition (when braking effect of
engine is showing in the drive line).
ON-VEHICLE SERVICE
REMOVAL
1) Hoist vehicle.
2) Before removing propeller shaft, give match mark (1) on pro-
peller shaft and companion flange as shown. Also give
match mark (1) on propeller shaft No.2 and center support
flange of propeller shaft No.1.
3) Loosen propeller shaft bolt at front and rear end, and sepa-
rate propeller shaft from transfer and rear differential.

BRAKES 5-9
EXCESSIVE PEDAL TRAVEL INSPECTION
1) Start engine.
2) Depress brake pedal a few times.
3) With brake pedal depressed with approximately 30 kg (66
lbs) load, measure brake pedal to wall (dash panel silencer)
clearance “a”.
If clearance “a” is less than specification, the most possible
cause is either rear brake shoes are worn out beyond limit or
air is in lines.
Should clearance “a” remain less than specification even
after replacement of brake shoes and bleeding of system,
other possible but infrequent cause is malfunction of rear
brake shoe adjusters or booster push rod length out of
adjustment.
–Bleed brake system. Refer to “AIR BLEEDING OF BRAKE
SYSTEM”.
–Remove brake drums for adjuster inspection. (Refer to
“REAR BRAKE”.) If defective, correct or replace.
Clearance “a” between brake pedal and dash panel
silencer
LH steering vehicle : over 135 mm (5.32 in.)
RH steering vehicle : over 140 mm (5.52 in.)
FRONT BRAKE PAD INSPECTION
Inspect pad linings (1) periodically according to maintenance
schedule whenever wheels are removed (for tire rotation or other
reason). Take a look through each end (or hole) of caliper and
check lining thickness of outside and inside pads.
If lining is worn and its thickness (“a” in figure) is less than limit, all
pads must be replaced at the same time.
Front brake pad thickness “a” (lining thickness)
Standard : 10 mm (0.40 in.)
Limit : 2 mm (0.08 in.)
BRAKE DISC INSPECTION
Refer to “BRAKE DISC” for inspection point and procedure.

BRAKES 5-11
Parking brake stroke (When lever is pulled up at 200 N (20
kg, 44 lbs)
: 4 to 9 notches
BOOSTER OPERATION INSPECTION
There are two ways to perform this inspection, with and without a
tester. Ordinarily, it is possible to roughly determine its condition
without using a tester.
CHECK AIR TIGHTNESS
1) Start engine.
2) Stop engine after running for 1 to 2 minutes.
3) Depress brake pedal several times with the same load as in
ordinary braking and observe pedal travel. If pedal goes
down deep the first time but its travel decreases as it is
depressed the second and more times, air tightness is
obtained.
4) If pedal travel doesn’t change, air tightness isn’t obtained.
CHECK OPERATION
1) With engine stopped, depress brake pedal several times
with the same load and make sure that pedal travel doesn’t
change. NOTE:
For this check, make sure that no air is in hydraulic line.
1. 1st
2. 2nd
3. 3rd
NOTE:
If defective, inspect vacuum lines and sealing parts, and
replace any faulty part.When this has been done, repeat
the entire test.
1. 1st, 2nd, 3rd

5-12 BRAKES
2) Start engine while depressing brake pedal. If pedal travel
increases a little, operation is satisfactory. But no change in
pedal travel indicates malfunction.
CHECK AIR TIGHTNESS UNDER LOAD
1) With engine running, depress brake pedal. Then stop engine
while holding brake pedal depressed.
2) Hold brake pedal depressed for 30 seconds. If pedal height
does not change, condition is good. But it isn’t if pedal rises.
FLUID PRESSURE TEST (IF EQUIPPED WITH
LSPV)
Test procedure for LSPV assembly is as follows.
Before testing, confirm the following.
Fuel tank is filled with fuel fully.
Vehicle is equipped with spare tire, tools, jack and jack han-
dle.
H: Hold
H: Hold
T: 30 seconds

COMES “ON” STEADY
CIRCUIT DESCRIPTION
EBD warning lamp (brake warning lamp) is controlled by parking brake switch, brake fluid level switch and ABS
control module/hydraulic unit assembly through lamp driver module in combination meter. Refer to “TABLE – A”
for circuit diagram.
INSPECTION
Step Action Yes No
1 1) Make sure that :
Parking brake is completely released.
Brake fluid level is upper than the minimum
level.
Are the check results OK?Go to Step 2. Release parking brake
completely and/or replen-
ish brake fluid.
2Does “ABS” warning lamp come on? Perform “TABLE – B” pre-
viously outlined.Go to Step 3.
3 1) Disconnect ABS hydraulic unit/control mod-
ule connector.
2) Check for proper connection to ABS
hydraulic unit/control module connector at
terminals “E19-10”.
3) If OK, apply chocks to wheels and select

connector to ground using service wire.
Does EBD warning lamp (brake warning lamp)
turn off?Substitute a known-good
ABS hydraulic unit/con-
trol module assembly and
recheck.“PNK/BLU” circuit open.
If wire and connection are
OK, replace combination
meter.

ANTILOCK BRAKE SYSTEM (ABS) 5E-27
DTC C1057 (DTC 57) – POWER SOURCE CIRCUIT
DESCRIPTION
The ABS control module monitors the power source voltage at terminal “E19-18”. When the power source volt-
age becomes extremely high or low, this DTC will be set. As soon as the voltage rises or lowers to the specified
level, the set DTC will be cleared.
INSPECTION
1. Ignition switch 3. ABS hydraulic unit/control module assembly
2. Main fuse 4. ABS hydraulic unit/control module connector
Step Action Yes No
1 1) Connect a voltmeter between battery posi-
tive (+) terminal and body ground.
2) Start the engine and measure the maximum
voltage when racing the engine.
Is it over 18V?Check charging system
referring to “CHARGING
SYSTEM” section.Go to Step 2.
2 1) Disconnect ABS hydraulic unit/control mod-
ule connector.
2) Keep the engine idling, measure the voltage
between terminal “E19-18” of ABS control
module and body ground.
Is it always under 9V?Check charging system
referring to “CHARGING
SYSTEM” section.
Imperfect short between
wire “GRN/ORN” and
ground.Poor connection of termi-
nal “E19-18” or “E19-24”
of the ABS control mod-
ule.
If the above are in good
condition, substitute a
known-good ABS hydrau-
lic unit/control module and
recheck.

For vehicles equipped with Supplemental Restraint (Air Bag) System :
Service on and around the air bag system components or wiring must be performed only by an
authorized SUZUKI dealer. Refer to “Air Bag System Components and Wiring Location View” under
“General Description” in air bag system section in order to confirm whether you are performing ser-
vice on or near the air bag system components or wiring. Please observe all WARNINGS and “Ser-
vice Precautions” under “On-Vehicle Service” in air bag system section before performing service
on or around the air bag 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.
Technical service work must be started at least 90 seconds after the ignition switch is turned to the
“LOCK” position and the negative cable is disconnected from the battery. Otherwise, the system
may be activated by reserve energy in the Sensing and Diagnostic Module (SDM).
NOTE:
Whether the following systems (parts) are used in the particular vehicle or not depends on vehicle
specifications. Be sure to bear this in mind when performing service work.
EGR valve
Heated oxygen sensor(s) or CO adjusting resistor
Three way catalytic converter
Immobilizer indicator lamp (vehicle with immobilizer indicator lamp can be identified also by HO2S-
