COOLING FAN CONTROL : System Description

INFOID:0000000012197685

INPUT/OUTPUT SIGNAL CHART

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

SYSTEM DESCRIPTION

ECM controls cooling fan speed corresponding to vehicle speed, engine coolant temperature, A/C ON signal

and refrigerant pressure.

Cooling fan control signal is sent to IPDM E/R from ECM by CAN communication line. Then, IPDM E/R sends

ON/OFF pulse duty signal to cooling fan control module. Corresponding to this ON/OFF pulse duty signal,

cooling fan control module gives cooling fan motor operating voltage to cooling fan motors. Cooling fan speed

is controlled by duty cycle of cooling fan motor operating voltage sent from cooling fan control module.

SYSTEM

SYSTEM DESCRIPTION

When rapid deceleration occurs during engine runs or idle speed decreases due to heavy load conditions,

ECM detects a decrease in idle speed and restarts the engine to secure reliability in handleability by transmit-

ting a cranking request signal to IPDM E/R for activating the starter motor under the following conditions:

• Selector lever: P or any position other than N

• Idle switch: ON (Accelerator pedal not depressed)

• Brake switch: ON (Brake pedal depressed)

Models with the Intelligent Key System transmit a control signal to IPDM E/R by way of BCM via CAN commu-

nication.

IPDM E/R detects an operating state of the starter motor relay and the starter motor control relay and trans-

mits a feed back signal to ECM via CAN Communication.

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.

System Description

INFOID:0000000012567241

The alternator power generation voltage variable control system controls the amount of power generation,

according to a battery loaded condition. ECM judges a battery condition, according to a signal received from

the battery current sensor which detects a charge/discharge current. ECM then transmits a signal to IPDM E/

R to command power generation via CAN communication. IPDM E/R transmits a power generation control sig-

nal to the alternator so that the system can control the amount of power generation. The voltage of power gen-

eration is lowered during battery low-load conditions and boosted under heavy load conditions. In this way, the

system reduces the engine load through the adequate power generation control.

BASIC ASCD SYSTEM

Refer to Owner's Manual for ASCD operating instructions.

Automatic Speed Control Device (ASCD) allows a driver to keep vehicle at predetermined constant speed

without depressing accelerator pedal. Driver can set vehicle speed in advance between approximately 40 km/

h (25 MPH) and 144 km/h (90 MPH).

ECM controls throttle angle of electric throttle control actuator to regulate engine speed.

Operation status of ASCD is indicated by CRUISE indicator and SET indicator in combination meter. If any

malfunction occurs in ASCD system, it automatically deactivates control.

Refer to 

EC-71, "AUTOMATIC SPEED CONTROL DEVICE (ASCD) : Switch Name and Function"

 for ASCD

operating instructions.

NOTE:

Always drive vehicle in safe manner according to traffic conditions and obey all traffic laws.
