5) Fix ignition timing to initial one as follow.
Select "MISC" mode on SUZUKI scan tool and fix ignition tim-
ing to initial one.
6) Detach air cleaner case and shift air cleaner case and hose
position to observe ignition timing.
7) Using timing light (1), check that ignition timing is within specifi-
cation.
Initial ignition timing (fixed with
SUZUKI scan tool)
Ignition order
8) If ignition timing is out of specification, check the followings:
D CKP sensor
D Crankshaft timing belt pulley (signal rotor)
D TP sensor
D VSS
D Timing belt cover installation
9) After checking Initial Ignition Timing, release ignition timing
fixation by using SUZUKI scan tool.
10) With engine idling (throttle opening at closed position and ve-
hicle stopped), check that ignition timing is about 9_–15_
BTDC. (Constant variation within a few degrees from 9_–15_
indicates no abnormality but proves operation of electronic tim-
ing control system.) Also, check that increasing engine speed
advances ignition timing.
If above check results are not satisfactory, check CKP sensor
and ECM (PCM).
11) Install air cleaner case.
