Cooling Fan
INFOID:0000000012198181
COOLING FAN CONTROL MODULE
Cooling fan control module receives ON/OFF pulse duty signal from IPDM E/R. Corresponding to this ON/OFF
pulse duty signal, cooling fan control module sends cooling fan motor operating voltage to cooling fan motor.
The revolution speed of cooling fan motor is controlled by duty cycle of the voltage.
COOLING FAN MOTOR
Cooling fan motor receives cooling fan motor operating voltage from cooling fan control module. The revolu-
tion speed of cooling fan motor is controlled by duty cycle of the voltage.
EVAP Canister Purge Volume Control Solenoid Valve
INFOID:0000000012198182
The EVAP canister purge volume control solenoid valve uses a ON/
OFF duty to control the flow rate of fuel vapor from the EVAP canis-
ter. The EVAP canister purge volume control solenoid valve is
moved by ON/OFF pulses from the ECM. The longer the ON pulse,
the greater the amount of fuel vapor that will flow through the valve.
EVAP Canister Vent Control Valve
INFOID:0000000012198183
The EVAP canister vent control valve is located on the EVAP canis-
ter and is used to seal the canister vent.
This solenoid valve responds to signals from the ECM. When the
ECM sends an ON signal, the coil in the solenoid valve is energized.
A plunger will then move to seal the canister vent. The ability to seal
the vent is necessary for the on board diagnosis of other evaporative
emission control system components.
This solenoid valve is used only for diagnosis, and usually remains
opened.
When the vent is closed, under normal purge conditions, the evapo-
rative emission control system is depressurized and allows “EVAP
Control System” diagnosis.

EVAP Control System Pressure Sensor
INFOID:0000000012198184
The EVAP control system pressure sensor detects pressure in the
purge line. The sensor output voltage to the ECM increases as pres-
sure increases.
Battery Current Sensor (With Battery Temperature Sensor)
INFOID:0000000012198185
OUTLINE
The power generation voltage variable control enables fuel con-
sumption to be decreased by reducing the engine load which is
caused by the power generation of the generator.
Based on sensor signals, ECM judges whether or not the power
generation voltage variable control is performed. When performing
the power generation voltage variable control, ECM calculates the
target power generation voltage based on the sensor signal. And
ECM sends the calculated value as the power generation command
value to IPDM E/R. For the details of the power generation voltage
variable control, refer to
CHG-8, "POWER GENERATION VOLTAGE
VARIABLE CONTROL SYSTEM : System Description"
CAUTION:
Never connect the electrical component or the ground wire directly to the battery terminal. The con-
nection causes the malfunction of the power generation voltage variable control, and then the battery
discharge may occur.
BATTERY CURRENT SENSOR
The battery current sensor is installed to the battery negative cable. The sensor measures the charging/dis-
charging current of the battery.
BATTERY TEMPERATURE SENSOR
Battery temperature sensor is integrated in battery current sensor.
The sensor measures temperature around the battery.
The electrical resistance of the thermistor decreases as temperature
increases.
<Reference data>
*: These data are reference values and are measured between battery temperature
sensor signal terminal and sensor ground.

Malfunction Indicator lamp (MIL)
INFOID:0000000012198186
Malfunction Indicator lamp (MIL) is located on the combination
meter.
MIL will illuminate when the ignition switch is turned ON without the
engine running. This is a bulb check.
When the engine is started, MIL should turn OFF. If the MIL remains
illuminated, the on board diagnostic system has detected an engine
system malfunction.
For details, refer to
EC-666, "DIAGNOSIS DESCRIPTION : Malfunc-
.
Control modules that a DTC of MIL ON/Blink is stored (Control mod-
ule varies among DTCs.):
• ECM
• TCM
Oil Pressure Warning Lamp
INFOID:0000000012198187
Oil pressure warning lamp is located on the combination meter.
It indicates the low pressure of the engine oil and the malfunction of
the engine oil pressure system.
Combination meter turns the oil pressure warning lamp ON/OFF
according to the oil pressure warning lamp signal received from
ECM via CAN communication.
For details, refer to
EC-644, "ENGINE PROTECTION CONTROL AT
LOW ENGINE OIL PRESSURE : System Description"
Refrigerant Pressure Sensor
INFOID:0000000012198188
The refrigerant pressure sensor is installed at the condenser of the air conditioner system. The sensor uses an
electrostatic volume pressure transducer to convert refrigerant pressure to voltage. The voltage signal is sent
to ECM, and ECM controls cooling fan system.
Manifold Absolute Pressure Sensor
INFOID:0000000012198189
The manifold absolute pressure (MAP) sensor is placed at intake
manifold collector. It detects intake manifold pressure and sends the
voltage signal to the ECM.
The sensor uses a silicon diaphragm which is sensitive to the
change in pressure. As the pressure increases, the voltage rises.

Stop Lamp Switch & Brake Pedal Position Switch
INFOID:0000000012198190
Stop lamp switch and brake pedal position switch are installed to brake pedal bracket.
ECM detects the state of the brake pedal by those two types of input (ON/OFF signal).
Clutch Interlock Switch
INFOID:0000000012198191
When the clutch pedal is depressed, the clutch interlock switch turns ON and the clutch interlock switch signal
is sent to the ECM. The ECM judges the clutch pedal conditions via the signal (ON or OFF).
Clutch Pedal Position Switch
INFOID:0000000012198192
When the clutch pedal is depressed, the clutch pedal position switch turns OFF and the clutch pedal position
switch signal is sent to the ECM. The ECM judges the clutch pedal conditions via the signal (ON or OFF).
ASCD Steering Switch
INFOID:0000000012198193
ASCD steering switch has variant values of electrical resistance for each button. ECM reads voltage variation
of switch, and determines which button is operated.
Information Display
INFOID:0000000012198194
The operation mode of the ASCD is indicated on the information display in the combination meter.
ECM transmits the status signal to the combination meter via CAN communication according to ASCD opera-
tion.
