Engine Electrical System

Ignition System

DESCRITION

Ignition timing is controlled by the electronic control ignition timing system. The standard reference ignition timing data

for the engine operating conditions are preprogrammed 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.
