Electronic control system

This model uses an electronic fuel injection control, ignition timing control, knock control, engine
speed control, Digital Electronic Control, electronic shift control, ETV control, and fail-safe control.
The engine ECM performs these controls based on data received from each sensor and switch.
The engine ECM is equipped with a self-diagnosis function. This function can be used to check trou-
ble codes on the YDIS.
It is also equipped with Y-COP as an anti-theft measure.
