5) Set timing light to ignition harness for No.1 cylinder.
6) Using timing light, check that timing observed from viewpoint
is within specification.
Initial ignition timing of viewpoint
(when it is fixed by SUZUKI scan tool) :
5 ± 1° BTDC
Ignition order :
1-6-5-4-3-2
Special tool
(A) : 09930-76420
7) If ignition timing is out of specification, loosen flange bolt,
adjust timing by turning CMP sensor (1) while engine is run-
ning, and then tighten bolt (2).
Tightening torque
CMP sensor bolt (a) : 15 N·m (1.5 kg-m, 11.0 lb-ft)
8) After tightening bolt (2), recheck that ignition timing is within
specification.
9) After checking and/or adjusting, end fixed spark mode of
SUZUKI scan tool.
10) With engine idling (closed throttle position and vehicle
stopped), check that ignition timing is about BTDC 12-16°
(shown in the figure). Also, check that increasing engine
speed advances ignition timing.
If above check results are not satisfactory, check input sig-
nals related to this system.
