2006 SUZUKI SX4 water pump

Downloaded from www.Manualslib.com manuals search engine Precautions: 00-6
• 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 disconnect 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 80 °C (176 °F) 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 water which will be a cause of a trouble.• Always be careful not to handle electrical parts
(computer, relay, etc.) in a rough manner or drop
them.
Warning for Wheel (with tire) RemovalS6RW0D0000003
WARNING!
When removing any of these wheels installed
using wheel bolts, never remove all wheel
bolts at the same time. Leave at least 1 bolt
for each wheel as it is to prevent wheel from
dropping. When removing this remaining 1
bolt, hold wheel and tire so as not to allow
them to come off.

THROTTLE MOTOR RELAY (ON/OFF)
ON: Throttle actuator (motor) control activated by ECM.
OF: Throttle actuator (motor) control stopped by ECM.
VEHICLE SPEED (km/h, mph)
It is computed based on pulse signals from front wheel
speed sensor (RH, LH) (for M/T model) or output shaft
speed sensor (VSS) (for A/T model).INJ PULSE WIDTH (FUEL INJECTION PULSE WIDTH,
msec.)
This parameter indicates time of the injector drive (valve
opening) pulse which is output from ECM (but injector
drive time of NO.1 cylinder for multiport fuel injection).
Visual InspectionS6RW0D1104008
Visually check the following parts and systems.
Engine Basic InspectionS6RW0D1104009
This check is very important for troubleshooting when ECM has detected no DTC and no abnormality has been found
in “Visual Inspection”.
Follow the flow carefully.Inspection item Reference section

deterioration, bend“Vacuum Hose Inspection in Section 1B”
• Connectors of electric wire harness – disconnection, friction
• Fuses – burning
• Parts – installation, bolt – looseness
• Parts – deformation
• Other parts that can be checked visually
Also check the following items at engine start, if possible
• Malfunction indicator lamp – Operation “Malfunction Indicator Lamp (MIL) Check”
• Charge warning lamp – Operation “Generator Symptom Diagnosis in Section 1J”
• Engine oil pressure warning lamp – Operation “Oil Pressure Switch Inspection in Section 9C”
• Engine coolant temp. meter – Operation“Engine Coolant Temperature (ECT) Sensor
Inspection in Section 1C”
• Fuel level meter – Operation “Fuel Level Sensor Inspection in Section 9C”
• Tachometer – Operation
• Abnormal air being inhaled from air intake system
• Exhaust system – leakage of exhaust gas, noise
• Other parts that can be checked visually
Step Action Yes No
1Was “Engine and Emission Control System Check”
performed?Go to Step 2. Go to “Engine and
Emission Control
System Check”.
2Check battery voltage
Is it 11 V or more?Go to Step 3. Charge or replace
battery.
3Is vehicle equipped with keyless start control system?Go to Step 4. Go to Step 5.

Performance check
1) Remove metal particles on end face of CMP sensor,
if any.
2) Arrange 12 V battery (1) and connect its positive
terminal to “Vin” terminal (2) and negative terminal to
“Ground” terminal (3) of sensor. Then using
ohmmeter, measure resistance between “Vout”
terminal (4) of sensor and negative terminal of
battery by passing magnetic substance (iron) (5)
while keeping approximately 1 mm (0.03 in.) gap
with respect to end face of CMP sensor.
If resistance does not vary as specified below,
replace CMP sensor.
