ELECTRONIC CONTROL SYSTEM
The electronic control system consists of 1) various
sensors which detect the state of engine and driving
conditions, 2) ECM which controls various devices ac-
cording to the signals from the sensors and 3) various
controlled devices.
Functionally, it is divided into the following sub sys-
tems:
D Fuel injection control system
D Ignition control system
NOTE:
Above figure shows left-hand steering vehicle. For right hand steering vehicle, parts with (:) are installed at
the other side.
