Nissan Rogue. Instruction — part 446
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
.
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
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

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.
