Electronic control system

The electronic control system is built up by the sensors and the ECM (Electric control Module).
The ECM receives signals from the sensors and determines the air and fuel mixture (A/F), and igni-
tion timing.
Under various condition, the ECM gives the best-suitable engine operation.
In addition, warning control, fail-safe control, a self-diagnosis function, etc., are equipped to
increase reliability.
