6F2-12 IGNITION SYSTEM (M13 ENGINE)
8) After checking Initial Ignition Timing, release ignition timing
fixation by using scan tool.
9) With engine idling (throttle opening at closed position and
car stopped), check that ignition timing is about 3° – 13°
BTDC. (Constant variation within a few degrees from 3° –
13° indicates no abnormality but proves operation of elec-
tronic timing control system.) Also, check that increasing
engine speed advances ignition timing.
If above check results are not satisfactory, check CKP sen-
sor and ECM.
