Yamaha F400A 2022 - Electronic Control System

Electronic control system
2-34
Electronic control system
This model uses an electronic direct injection control, digital ignition control, Digital Electronic Control,
electronic shift control, ETV control, VCT control, knock control, over-revolution control, alert 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 trouble
codes on the YDIS.
It is also equipped with Y-COP as an anti-theft measure (optional).
