9. After checking and/or adjusting, end fixed spark mode of SUZUKI scan tool.
NOTE: In this state, ignition timing may vary more or less of initial ignition timing but it is nothing abnormal.
10. With engine idling (closed throttle position and vehicle stopped), check that ignition timing is about BTDC 12° - 16° (for J20 (2.0L) engine), 11° -
15° (for H25 (2.5L) engine) (shown in the figure). Also, check that increasing engine speed advances ignition timing.
If above check results are not satisfactory, check input signals related to this system.
