Engine and Emission Control System Description
S4RS0A1101004
The engine and emission control system is divided into 4 major sub-systems: air intake system, fuel delivery system,
electronic control system and emission control system.
Air intake system includes air cleaner, throttle body, IAC valve and intake manifold.
Fuel delivery system includes fuel pump, delivery pipe, etc.
Electronic control system includes ECM, various sensors and controlled devices.
Emission control system includes EGR, EVAP and PCV system.
CAN Communication System Description
S4RS0A1101008
ECM (2), TCM (equipped with A/T) (1), BCM (3) and combination meter (4) of this vehicle communicate control data
between each control module.
Communication of each control module is established by CAN (Controller Area Network) communication system.
CAN communication system uses the serial communication in which data is transmitted at a high speed. It uses a
twisted pair of two communication lines for the high-speed data transmission. As one of its characteristics, multiple
control modules can communicate simultaneously. In addition, it has a function to detect a communication error
automatically. Each module reads necessary data from the received data and transmits data. ECM communicates
control data with each control module as follows.
