The electronic control system consists of various sensors, switches, ECUs which detect the state of engine and driving conditions, and ECM which controls various electric control devices according to the signals from various sensors and various electric control devices.
Functionally, it is divided into the following subsystems:
- Fuel injection control system
- Ignition control system
- Electric throttle control system
- Fuel pump control system
- Radiator cooling fan control system
- Evaporative emission control system
- A/F sensor heater control system
- HO2S heater control system
- A/C control system
- Immobilizer control system
- Communication system among control modules
ECM is using CAN communication to communicate with other control module. For more detail of CAN communication, refer to COMMUNICATION SYSTEM DESCRIPTION .
