6E2-20 ENGINE AND EMISSION CONTROL SYSTEM (SFI FOR G13)
[Using SUZUKI scan tool]
a) Connect SUZUKI scan tool to DLC with ignition switch OFF.
b) Turn ignition switch ON and then select “DATA LIST” mode on
scan tool.
c) Make sure that vehicle condition is as following.
D Vehicle speed = 0 KPH
D Engine speed = 0 RPM
D Fuel tank level y 15%
d) Clear DTC by using “CLEAR INFO” mode.
e) Check fuel pressure by using “FUEL PUMP CONT” mode in
“MISC TEST” menu.
CONDITION FUEL PRESSURE
With fuel pump operating
2.7 – 3.1 kg/ cm
2
270 – 310 kPa
38.4 – 44.0 psi
Within 1 min. after fuel pump
stop (Pressure reduces as
time passes)
Over 2.0 kg/ cm
2
200 kPa
28.4 psi
If measured pressure doesn’t satisfy specification, refer to
“Diagnostic Flow Table B-3” and check each possibly defective
part. Replace if found defective.
f) Start engine and warm it up to normal operating temperature.
And then check fuel pressure.
CONDITION FUEL PRESSURE
At specified idle speed
2.0 – 2.4 kg/ cm
2
200 – 240 kPa
28.4 – 34.1 psi
If measured pressure doesn’t satisfy specification, refer to
“Diagnostic Flow Table B-3” and check each possibly defective
part. Replace if found defective.
g) After checking fuel pressure, remove fuel pressure gauge.
CAUTION:
As fuel feed line is still under high fuel pressure, make
sure to release fuel pressure according to following pro-
cedures.
D Place fuel container under joint.
D Cover joint with rag and loosen joint nut slowly to re-
lease fuel pressure gradually.
h) Remove special tools from fuel delivery pipe.
i) Connect fuel feed hose to fuel delivery pipe and clamp it secure-
ly.
j) With engine OFF and ignition switch ON, check for fuel leaks.
