If ignition timing is out of specification, loosen flange bolts (2), adjust timing by turning CMP sensor (1) while engine is running, and then tighten bolts. Tighten CMP sensor bolt to 11.0 ft. lbs. (15 Nm)
After tightening bolts, recheck that ignition timing is within specification.
After checking and/or adjusting, release fixed ignition timing and disconnect SUZUKI scan tool from DLC.
With engine idling (closed throttle position switch ON and vehicle stopped), check that ignition timing vary more or less of initial ignition timing (about 8°). Also, check that increasing engine speed
advances ignition timing. If the check results are not satisfactory, check TP sensor and ECM.
