Diagnostic Information and Procedures
EGR System InspectionS7RS0B1204001
1) Connect SUZUKI scan tool to data link connector (DLC) with ignition switch turned OFF.
2) Turn ON ignition switch and erase DTC using “CLEAR DTC” in “TROUBLE CODES” menu.
3) Start engine and warm it up to normal operating temperature, then select “DATA LIST” mode on scan
tool.
4) Make sure that vehicle condition is as follows.
• Vehicle speed = 0 km/h (0 KPH)
• Engine speed ≤ 900 rpm
• Engine coolant temp. ≥ 90 °C, 164 °F
5) With engine idling (without depressing accelerator pedal), open EGR valve by using “STEP EGR” mode
in “MISC TEST” menu. In this state, as EGR valve
opening increases engine idle speed drops. If not,
possible cause is clogged EGR gas passage, stuck
or faulty EGR valve.
Repair Instructions
EVAP Canister Purge InspectionS7RS0B1206001
NOTE
Before inspection, check to make sure that gear shift lever is in neutral position (with A/T model,
selector lever in “P” range) and that parking brake lever is pulled all the way up.

1) Disconnect purge hose (1) from EVAP canister (2).
2) Place finger against the end of disconne cted hose and check that vacuum is not felt there when engine is cool and
running at idle speed. If check result is not satisfacto ry, check EVAP canister purge valve, wire harness and ECM.

EVAP Canister Purge Valve and Its Circuit
Inspection
S7RS0B1206002
WARNING!
Do not apply vacuum by mouth; otherwise
harmful fuel vapor can be breathed in.

CAUTION!
Do not apply vacuum more than –86 kPa (–
12.47 psi); otherwise EVAP canister purge
valve could be damaged.

1) Prepare to operate EVAP canister purge valve as follows.
a) When using SUZUKI scan tool:
i) Connect SUZUKI scan tool to DLC (1) with ignition switch turned OFF and disconnect
purge valve vacuum hoses from intake
manifold and EVAP canister.
ii) Turn ON ignition switch, clear DTC and select “MISC TEST” mode on SUZUKI scan
tool.
Special tool
(A): SUZUKI scan tool b) When not using SUZUKI scan tool:
NOTE
Before performed this check, be sure to read
the “Precautions of ECM Circuit Inspection in
Section 1A”.

i) Disconnect purge valve vacuum hoses from
intake manifold and EVAP canister.
ii) Remove ECM from it s bracket referring to
“ECM Removal and Inst allation in Section
1C”.
iii) Connect special tool between ECM and ECM connector referring to “Inspection of ECM
and Its Circuits in Section 1A”
iv) Turn ON ignition switch. Using service wire, ground “C37-29” terminal
circuit of special tool (valve ON: “B”) and
unground it (valve OFF: “A”).
2) Check purge valve for operation and vacuum passage for clog when valve is switched ON and
OFF by using SUZUKI scan tool or service wire.
If check result is not satisfactory, check vacuum
hoses, EVAP canister purge valve, wire harness and
connections.
EVAP canister purge valve specification
[A] Valve OFF: When vacuum (–60 kPa (–8.7 psi))
is applied to hose (1), vacuum can be applied.
[B] Valve ON: When vacuum is applied to hose
(1), vacuum can not be applied.

Vacuum Passage InspectionS7RS0B1206003
Start engine and run it at idle speed. Disconnect vacuum
hose (1) from EVAP canister purge valve (2). With finger
placed against disconnected hose, check that vacuum is
applied.
If it is not applied, clean vacuum passage by blowing
compressed air.
Vacuum Hose and Purge Valve Chamber
Inspection
S7RS0B1206004
Check hoses and purge valv e chamber for connection,
leakage, clog and deterioration.
Replace as necessary.
EVAP Canister Purge Valve InspectionS7RS0B1206005
WARNING!
Do not apply vacuum by mouth; otherwise
harmful fuel vapor can be breathed in.

CAUTION!
Do not apply vacuum more than –86 kPa (–
12.47 psi); otherwise EVAP canister purge
valve could be damaged.

1) With ignition switch turned OFF, disconnect coupler and vacuum hoses from canister purge valve.
2) Remove EVAP canister purge valve from air cleaner assembly.
3) Check resistance between two terminals of EVAP canister purge valve.
If resistance is not as specified, replace EVAP
canister purge valve.
EVAP canister purge valve resistance
30 – 34 Ω at 20 °C (68 °F) 4) With coupler disconnected, apply vacuum (–60 kPa
(–8.7 psi)) to pipe (1). If vacuum can be applied, go
to next step. If vacuum can not be applied, replace
EVAP canister purge valve.
5) In this state, connect 12 V-battery to EVAP canister purge valve terminals. If vacuum can not be applied,
EVAP canister purge valve is in good condition.
If applied, replace EVAP canister purge valve.
WARNING!
Do not suck the air through valve. Fuel vapor
inside valve is harmful.

Special tool
(A): 09917–47011
6) Install EVAP canister purge valve to air cleaner assembly.

If found faulty, replace EGR valve assembly.
EGR valve resistance (A – B, C – B, F – E, D – E
terminal)
20 – 24 Ω
2) Remove carbon from EGR valve gas passage.
CAUTION!
Do not use any sharp-edged tool to remove
carbon.
Be careful not to damage or bend EGR valve
(1), valve seat (3) and rod.

3) Inspect valve (2), valve seat and rod for fault, cracks, bend or other damage.
If found faulty, replace EGR valve assembly.
PCV Hose InspectionS7RS0B1206009

5) Warm up engine to the normal operating temperature and keep it at the specified idle speed.
6) Turn A/C switch ON, set blower speed selector at maximum speed position, temperature selector at
maximum cold position, airflow selector at face
position, and air intake switch at recirculation
position. (Confirm that A/C compressor and
condenser fans are working.)
7) Wait for ten minutes to stabilize the A/C operation.
8) Open front windows, front doors and engine hood.
9) With about 20 mm (0.8 in.) of dry bulb thermometer
(1) put right in front of center ventilation louver and a
wet and dry bulb thermometer (2) near air inlet of
HVAC unit. 10) Check for each pressure of low side and high side if
it is within shaded range of graph. If each gauge
reading is out of specified pressure, correct defective
part referring to the following table.
NOTE
Pressure registered on gauge varies with
ambient temperature. Therefore, use the
graphs when determining if pressures are
normal or not.

Low side and high side pressure example,
Gauges should read as follows when ambient
temperature is 30 °C (86 °F)
Pressure on high pressure gauge (HI): 1590 –
1940 kPa (15.9 – 19.4 kg/cm2)
Pressure on low pressure gauge (LO): 270 – 430
