EC-52

< SYSTEM DESCRIPTION >

[QR25DE]

SYSTEM

When a malfunction which causes damage to the catalyst is

detected, ECM immediately blinks MIL to alert the driver. 

BULB CHECK

The bulb turns ON after turning ON the ignition switch (engine stop) and turns OFF after restarting the engine.

OPERATION AT COMBINATION METER CAN COMMUNICATION CUT-OFF OR UNUSUAL SIG-
NAL

For the operation for CAN communication blackout in the combination meter, refer to 

MWI-30, "Fail-safe"

SYSTEM DIAGRAM

SIGNAL PATH

• When the lighting conditions of the malfunction indicator lamp (MIL) are satisfied, ECM transmits a malfunc-

tion indicator lamp (MIL) signal to the combination meter via CAN communication.

• The combination meter turns ON or blinks the malfunction indicator lamp (MIL), according to a signal

received from ECM. 

LIGHTING CONDITION

When all of the following conditions are satisfied:

• Ignition switch: ON

• DTC which influences on exhaust gasses is judged.

For DTCs that the malfunction indicator lamp turns ON and the number of DTC diagnosis trips, refer to 

EC-96,

"DTC Index"

.

SHUTOFF CONDITION

When any of the following conditions is satisfied: 

• Ignition switch: OFF

• Erase  DTC

NOTE:

For the conditions of erasing DTC, refer to 

EC-59, "DIAGNOSIS DESCRIPTION : DTC and Freeze Frame

Data"

.

DESIGN/PURPOSE

When engine oil pressure is low, the engine oil pressure warning informs the driver of low oil pressure to pre-

vent damage to the engine.

EVAPORATIVE EMISSION SYSTEM : System Description

INFOID:0000000011277871

SYSTEM DIAGRAM

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.

CAN COMMUNICATION
CAN COMMUNICATION : System Description

INFOID:0000000011277872

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.
