Electronic control system

These models use electronic fuel injection control, digital ignition control, VCT control, knock con-
trol, over-rev control, alert control, ETV control, and fail-safe control. The engine ECM performs
these controls according to the signals sent from various sensors and switches.
In addition, the engine ECM has a self-diagnosis function to perform troubleshooting using the
YDIS.
The 6Y8 Multifunction Meter can be installed as an option.
