When the RESUME/ACCELERATE switch is pressed after cancel operation other than pressing MAIN switch

is performed, vehicle speed will return to last set speed. To resume vehicle set speed, vehicle condition must

meet following conditions.

• Brake pedal is released

• A/T selector lever is in other than P and N positions

• Vehicle speed is greater than 40 km/h (25 MPH) and less than 144 km/h (89 MPH)

CAN COMMUNICATION

CAN COMMUNICATION

System Description

INFOID:0000000009886497

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

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-46, "CAN System Specification Chart"

about CAN communication for detail.

EVAPORATIVE EMISSION SYSTEM

Description

INFOID:0000000009886498

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.
