Scan Tool DataS7RS0B1104007
As the data values are standard values estimated on the basis of values obtained from the normally operating vehicles
by using a scan tool, use them as re ference values. Even when the vehicle is in good condition, there may be cases
where the checked value does not fall within each specified data range. Therefore, judgment as abnormal should not
be made by checking with these data alone.
Also, conditions that can be checked by the scan tool are those detected by ECM and output from ECM as commands
and there may be cases where the engine or actuator is not operating (in the condition) as indicated by the scan tool.
Be sure to use the timing light to check the ignition timing.
NOTE
• There are two types of OBD system depending on the vehicle specification.
For details, refer to “Precaution on On-Board Diagnostic (OBD) System”.
• With the generic scan tool, only star (*) marked data in the following table can be read.
• When checking the data with the engine running at idle or racing, be sure to shift M/T gear to the neutral position and A/T gear to the “Park” position and pull the parking brake fully. Also, if nothing
or “no load” is indicated, turn O FF A/C (if equipped with A/C), all electric loads, P/S and all the other
necessary switches.

• ECM turns off throttle actuator control relay and throttle valve is fixed at the specified opening from
its completely closed position (default opening).

Idle Speed and IAC Throttle Valve Opening
Inspection
S7RS0B1106001
Before idle speed check, make sure of the following.
• Lead wires and hoses of electronic fuel injection and engine and emission control systems are connected
securely.
• Valve lash is checked according to maintenance schedule.
• Ignition timing is within specification.
• All accessories (wipers, heater, lights, A/C, etc.) are out of service.
• Air cleaner has been properly installed and is in good condition.
• No abnormal air drawn in from air intake system.
After all items are confirmed, check idle speed and IAC
duty as follows.
NOTE
Before starting engine, place transmission
gear shift lever in “Neutral” (shift selector
lever to “P” range for A/T vehicle), and set
parking brake and block drive wheels.

1) Connect SUZUKI scan tool to DLC (1) with ignition
switch turned OFF.
Special tool
(A): SUZUKI scan tool 2) Warm up engine to normal operating temperature.
3) Check engine idle speed and “IAC throttle opening”
by using “Data List” mode on scan tool to check “IAC
throttle opening”.
4) If check result is out of sp ecification, inspect electric
throttle body assembly referring to “Electric Throttle
Body Assembly On-Vehicle Inspection in Section
1C”.
Engine idle speed
A/C OFF: 700 ± 50 rpm (IAC duty: 5 – 55%)
A/C ON: 850 ± 50 rpm
5) Check that specified engine idle speed is obtained with A/C turned ON if vehi cle is equipped with A/C.
If not, check A/C system.

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.

Compression CheckS7RS0B1404001
Check compression pressure on all 4 cylinders as
follows:
1) Warm up engine to normal operating temperature.
2) Stop engine after warming up.
NOTE
After warming up engine, place transaxle
gear shift lever in “Neutral”, and set parking
brake and block drive wheels.

3) Disconnect negative cable at battery.
4) Remove engine cover.
5) Remove air cleaner assembly and air suction hose referring to “Air Cleaner Components”.
6) Remove cylinder head upper cover.
7) Disconnect ignition coil couplers (1).
8) Remove ignition coil assemblies (2) with high- tension cord (3).
9) Remove all spark plugs.
10) Disconnect fuel injector wires (4) at the coupler. Driving condition Valve timing Target of control Effect
