EVAPORATIVE EMISSION SYSTEM : System Description

INFOID:0000000010986247

SYSTEM DIAGRAM

*: ECM determines the start signal status by the signals of engine speed and battery voltage.

SYSTEM DESCRIPTION

The evaporative emission system is used to reduce hydrocarbons emitted into the atmosphere from the fuel
system. This reduction of hydrocarbons is accomplished by activated charcoals in the EVAP canister.
The fuel vapor in the sealed fuel tank is led into the EVAP canister which contains activated carbon and the
vapor is stored there when the engine is not operating or when refueling to the fuel tank.
The vapor in the EVAP canister is purged by the air through the purge line to the intake manifold when the
engine is operating. EVAP canister purge volume control solenoid valve is controlled by ECM. When the
engine operates, the flow rate of vapor controlled by EVAP canister purge volume control solenoid valve is
proportionally regulated as the air flow increases.
EVAP canister purge volume control solenoid valve also shuts off the vapor purge line during decelerating and
idling.

CAN COMMUNICATION

CAN COMMUNICATION : System Description

INFOID:0000000010986248

CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2

SYSTEM

communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
Refer to 

LAN-8, "System Description"

, about CAN communication for detail.

ECO MODE CONTROL

ECO MODE CONTROL : System Description

INFOID:0000000010986249

SYSTEM DESCRIPTION

ECM receives an ECO mode signal from TCM via CAN communication and improves the fuel economy by
controlling the throttle movement to less than usual.
For details of ECO mode system, refer to 

DMS-7, "ECO MODE CONTROL : System Description"

ON BOARD DIAGNOSTIC (OBD) SYSTEM

ON BOARD DIAGNOSTIC (OBD) SYSTEM

Diagnosis Description

INFOID:0000000010986251

This system is an on board diagnostic system that records exhaust emission-related diagnostic information
and detects a sensors/actuator-related malfunction. A malfunction is indicated by the malfunction indicator
lamp (MIL) and stored in control module memory as a DTC. The diagnostic information can be obtained with
the diagnostic tool (GST: Generic Scan Tool).

GST (Generic Scan Tool)

INFOID:0000000010986252

When GST is connected with a data link connector equipped on the vehicle side, it will communicate with the
control module equipped in the vehicle and then enable various kinds of diagnostic tests. Refer to 

EC-480,

"Diagnosis Description"

.

NOTE:
Service $0A is not applied for regions where it is not mandated.
