Electronic Control System Description

The electronic control system consists of 1) various sensors which detect the state of engine and driving conditions, 2) ECM which controls various devices according to the signals from the sensors and 3) various controlled devices. Functionally, it is divided into the following sub systems:

• Fuel injection control system
• Heated oxygen sensor heater control system
• Idle air control system
• Fuel pump control system
• Evaporative emission control system
• Ignition control system
• EGR system
• Intake air valve control system

Also ECM (Engine Control Module), TCM (Transmission Control Module) and BCM (Body Electrical Control Module) are communicated by CAN (Controller Area Network).
