4) Check that battery voltage is 11 V or more.
5) Measure fuel pressure at each condition.If measured pressure is out of specification, refer to
“Fuel Pressure Check in Section 1A” and check each
possibly defective part. Replace if found defective.
a) Turn ignition switch ON to operate fuel pump and after 2 seconds turn it OFF. Repeat this 3 or 4
times and then check fuel pressure.
Fuel pressure specification
With fuel pump operating and engine
stopped: 270 – 310 kPa (2.7 – 3.1 kg/cm2, 38.4
– 44.0 psi)
b) Start engine and warm it up to normal operating temperature, and measure fuel pressure at
idling.
Fuel pressure specification
At specified idle speed: 270 – 310 kPa (2.7 –
3.1 kg/cm2, 38.4 – 44.0 psi)
c) Stop engine, and measure fuel pressure at one minute after stopping.
Fuel pressure specification
With 1 min. after engine (fuel pump) stop
(Pressure reduces as time passes): Over 300
kPa (3.0 kg/cm
2, 42.7 psi)
6) After checking fuel pressure, remove fuel pressure gauge.
WARNING!
As fuel feed line is still under high fuel
pressure, make sure to release fuel pressure
according to the following procedures.
• Place fuel container under joint.
• Cover joint with rag and loosen joint nut slowly in order to release fuel pressure
gradually.

7) Remove special tools from fuel delivery pipe and fuel feed hose.
8) Connect fuel feed hose to fuel delivery pipe and clamp it securely.
9) With engine OFF and ignition switch ON, check for fuel leaks.
Fuel Cut Operation InspectionS7RS0B1704002
NOTE
Before inspection, make sure that gear shift
lever is in neutral positi on (shift select lever
is “P” range for A/T vehicle), A/C is OFF and
parking brake lever is pulled all the way up.

1) Warm engine up to normal operating temperature.
2) While listening to sound of injector (2) by using sound scope (1) or such, increase engine speed to
higher than 3,000 r/min.
3) Check to make sure that injector operation sound is stop when throttle valve is closed instantly and it is
heard again when engine speed is reduced to
approx. 2,000 r/min or less.

6) Set timing light (1) to high-tension cord for No.1 cylinder and check that ignition timing is within
specification.
Initial ignition timing
Fixed with SUZUKI scan tool: 5 ± 3° BTDC (at
specified idle speed)
Ignition order
1 – 3 – 4 – 2
Special tool
(A): 09930–76420 7) If ignition timing is out
of specification, check the
followings.
• CKP sensor
• CKP sensor plate
• CMP sensor
• CMP sensor rotor tooth of camshaft
• VSS
• Timing chain cover installation
8) After checking initial igniti on timing, release ignition
timing fixation by using scan tool.
9) With engine idling (throttl e opening at closed position
and vehicle stopped), check that ignition timing is
about 3 ° – 13° BTDC. (Constant variation within a
few degrees from 3 ° – 13° BTDC indicates no
abnormality but proves operation of electronic timing
control system.) Also, check that increasing engine
speed advances ignition timing.
If the check results are not satisfactory, check CKP
sensor and ECM.

Generator Test (Undercharged Battery Check)S7RS0B1A04003
This condition, as evidenced by slow cranking or
indicator clear with dark or light yellow dot can be
caused by one or more of the following conditions even
though indicator lamp may be operating normal.
The following procedure also applies to cars with
voltmeter and ammeter.1) Make sure that undercharged condition has not been caused by accessories left on for extended period of
time.
2) Check drive belt for proper tension.
3) If battery defect is suspected, refer to “Battery Description”.
4) Inspect wiring for defects. Check all connections for tightness and cleanliness, battery cable connections
at battery, starting motor, ignition ground cable and
no “C” terminal circuit at ground.
5) Connect switch (6), load (5), battery (4), voltmeter (3) and ammeter (2) to generator (1) as shown in
figure.
Voltmeter: Set between generator “B” terminal
and ground.
Ammeter: Set between generator “B” terminal
and battery (+) terminal.
NOTE
Use fully charged battery.

6) Measure current and voltage.
No-Load Check 1) Run engine from idling up to 2000 rpm and read meters.
NOTE
Turn off switches of all accessories (wiper,
heater etc.).

Specification for undercharged battery (No-load
check)
Current: 10 A
Voltage: 14.2 – 14.8 V (at 20 °C, 68 °F)
NOTE
Consideration should be taken that voltage
will differ somewhat with regulator case
temperature as shown in figure.

2) Using service wire, ground “C” terminal (1) of
generator.
3) Measure voltage between “B” terminal of generator and body ground.
Voltage: 12.5 – 13.1 V (at 20 °C, 68 °F)
• If voltage is higher than standard value
If voltage is higher than standard value, check ground
of brushes.
If brushes are not grounded, replace IC regulator.
If voltage is lower than standard value, proceed to the
following check.
Load Check 1) Run engine at 2000 rpm and turn on head light and blower motor.
2) Measure current. If measure current is less than 30 A, repair or
replace generator.

Troubleshooting
Time Lag TestS7RS0B5104015
This test is to check conditions of clutch, brake and fluid pressure. “Time lag” means time elapsed since select lever is
shifted with engine idling till shock is felt.
1) With chocks placed before and behind front and rear wheels respectively, depress brake pedal.
2) Start engine.
3) With stop watch ready, shift select lever from “N” to “D” range an d measure time from that moment till shock is felt.
4) Similarly measure time lag by shifting select lever from “N” to “R” range.
Gear shifting time lag
“N” → “D”: Less than 0.7 sec.
“N” → “R”: Less than 1.2 sec.
NOTE
• When repeating this test, be sure to wait at least one minute after select lever is shifted back to “N”
range.
• Engine should be warmed up fully for this test.
• Repeat test 3 times and take average of those data for final time lag data.

A/T Fluid Level CheckS7RS0B5106002
CAUTION!
Do not use any fluid other than the specified
ATF. Use of any fluid other than the specified
ATF may cause juddering or some other
faulty condition to occur.

Level Check at Normal Operating (Hot) Temperature
– Hot Check1) Drive vehicle so that A/T fluid temperature reach the
normal operating temperature (70 – 80 °C (158 –
176 °F)).
2) Stop vehicle with engine running and place it level.
3) With select lever at “P” range, apply parking brake and place chocks against wheels.
4) Keep engine idling and shift selector slowly to “L” and back to “P” position.
5) With engine idling, pull out fluid level gauge, wipe it off with a clean cloth and put it back into place.
6) Pull out fluid level gauge (1) again and check fluid level indicated on it. The lo west fluid level should be
between FULL HOT (2) and LOW HOT (3). If it is
below LOW HOT, add SUZUKI ATF 3317 or Mobil
ATF 3309 up to FULL HOT.
Automatic transaxle fluid
SUZUKI ATF 3317 or Mobil ATF 3309
NOTE
• Do not race engine while checking fluid level, even after the engine start.
• Do not overfill. Overfilling can cause foaming and loss of fluid through breather.
Then slippage and transaxle failure can
result.
• Bringing the level from LOW HOT to FULL HOT requires 0.4 liters (0.85 / 0.70 US/Imp.
pt).
• If vehicle was driven under high load such as pulling a trailer, fluid level should be
checked about half an hour after it is
stopped.

Level Check at Room (Cold) Temperature – Cold
Check
Fluid level can be checked temporarily at room (cold)
temperature which correspond to 20 – 30 °C (68 – 86
° F). This level check is considered to be preparation
before performing level check under normal operating
(hot) temperature. Checking procedure itself is the same
as that described in “Level Check at Normal Operating
(Hot) Temperature – Hot Check: ”. If fluid level is
between “FULL COLD” (4) and “LOW COLD” (5),
proceed to test drive. And when fluid temperature has
reached normal operating temp erature, check fluid level
again and adjust it as necessary.
CAUTION!
Fluid level check at room (cold) temperature
is recommended only for preparation of level
check under normal (hot) operating
condition.
Failure to perform fluid level check under
normal (hot) operating temperature may
result in damage to transaxle.
