ENGINE BASIC INSPECTION
This check is very important for troubleshooting when ECM (PCM) has detected no DTC and no abnormality has
been found in visual inspection.
Follow the flow table carefully.
STEP
ACTIONYESNO
1Was “ENGINE DIAG. FLOW TABLE” performed?Go to Step 2.Go to “ENGINE DIAG.
FLOW TABLE”.
2Check battery voltage.
Is it 11 V or more?Go to Step 3.Charge or replace
battery.
3Is engine cranked?Go to Step 4.Go to “DIAGNOSIS”
in Section 6G.
4Does engine start?Go to Step 5.Go to Step 7.
5Check idle speed as follows:
1) Warm up engine to normal operating temp.
2) Shift transmission to neutral position for M / T
(“P” position for A / T).
3) All of electrical loads are switched off.
4) Check engine idle speed with scan tool.
See Fig. 1.
Is it 700 – 800 r / min?Go to Step 6.“ENGINE DIAGNO-
SIS TABLE” in this
section.
6Check ignition timing as follows:
1) Using SUZUKI scan tool, select “MISC” mode on
SUZUKI scan tool and fix ignition timing to initial
one. See Fig. 2.
2) Remove air cleaner bolt and shift air cleaner
position to observe ignition timing.
3) Using timing light (1), check initial ignition timing.
See Fig. 3.
Is it 5 ± 3 BTDC at specified idle speed?“ENGINE DIAGNO-
SIS TABLE” in this
section.Check ignition control
related parts referring
to Section 6F1.
7Check fuel supply as follows:
1) Check to make sure that enough fuel is filled in fuel
tank.
2) Turn ON ignition switch for 2 seconds and then
OFF. See Fig. 4.
Is fuel return pressure (returning sounds) felt from fuel
feed hose (1) when ignition switch is turned ON?Go to Step 9.Go to Step 8.
8Check fuel pump for operating.
1) Was fuel pump operating sound heard from fuel
filler for about 2 seconds after ignition switch ON
and stop?Go to “DIAG. FLOW
TABLE B-3”.Go to “DIAG. FLOW
TABLE B-2”.
9Check ignition spark as follows:
1) Disconnect injector couplers.
2) Remove spark plugs and connect them to high
tension cords.
3) Ground spark plugs.
4) Crank engine and check if each spark plug sparks.
Is it in good condition?Go to Step 10.Go to “DIAGNOSIS”
in Section 6F1.
10Check fuel injector for operation as follows:
1) Install spark plugs and connect injector
connectors.
2) Using sound scope (1), check operating sound of
each injector (2) when cranking engine. See Fig. 5.
Was injector operating sound heard from all
injectors?“ENGINE DIAGNO-
SIS TABLE” in this
section.Go to “DIAG. FLOW
TABLE B-1”.

1Was “ENGINE DIAG. FLOW TABLE” performed?Go to Step 2.Go to “ENGINE
DIAG. FLOW
TABLE”.
2Check VSS for Resistance.
1) Disconnect VSS connection with ignition switch OFF.
2) Check for proper connection to VSS at “P” and “Bl” wire
terminals.
3) If OK, then check resistance of VSS. See Fig. 1.
Resistance between terminals : 100 – 300 Ω
Resistance between terminal
and transmission : 1 MΩ or more
Are check result satisfactory?Go to Step 3.Replace VSS.
3Check Visually VSS and Counter Shaft Gear for the
Following. See Fig. 2.

No damage

No foreign material attached
