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 table carefully.

2 Check battery voltage.
Is it 11 V or more?
3 Is engine cranked?
4 Does engine start?
5 Check 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 650 – 750 r/min (700 – 800 r/min. for A/T
vehicle)?
6 Check ignition timing as follows :
1) When SUZUKI scan tool is not available,
disconnect scan tool from DLC and connect
test switch terminal of monitor connector to
ground. See Fig. 2.
When using SUZUKI scan tool, select
"MISC" mode on SUZUKI scan tool and fix
ignition timing to initial one. See Fig. 3.
2) Using timing light (1), check initial ignition
timing. See Fig. 4.
Is it 5° ± 3° BTDC at specified idle speed?
7 Is immobilizer control system equipped?
8 Check immobilizer system malfunction as fol-
lows.
1) Check immobilizer indicator lamp or MIL

Is it flashing when ignition switch is turned to
