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 Test switch signal circuit
D VSS
D Timing belt cover installation
9) After checking Initial Ignition Timing, release ignition timing
fixation by using SUZUKI scan tool or disconnect service wire
from diagnosis connector 1.
10) With engine idling (test switch terminal ungrounded, throttle
opening at closed position and car stopped), check that igni-
tion timing is about 9_–15_ BTDC. (Constant variation within
a few degrees from 9_–15_ indicates no abnormality but
proves operation of electronic timing control system.) Also,
check that increasing engine speed advances ignition timing.
If above check results are not satisfactory, check CKP sensor,
test switch terminal circuit and ECM.
11) Install air cleaner upper case.
