Ignition timing is
controlled by the electronic control ignition timing system.
The standard reference
ignition timing data for the engine operating conditions are pre-pro
grammed in the memory of the ECM (Engine Control Module).
The engine operating
conditions (speed, load, warm-up condition, etc.) are detected by the
various sensors. Based on these sensor signals and the ignition timing
data, signals to interrupt the primary current are sent to the ECM.
The ignition coil is
activated, and timing is controlled.
