COMPONENT PARTS
ECM receives the signals as shown in the figure.
Clutch Pedal Position SwitchINFOID:0000000012431275
When the clutch pedal is depressed, the clutch pedal pos
ition switch turns OFF and the clutch pedal position
switch signal is sent to the ECM. The ECM judges t he clutch pedal conditions via the signal (ON or OFF).
Cooling FanINFOID:0000000012431276
Cooling fan operates at low and high speed when the current flows in the cooling fan motor.
Refer to EC-38, "
COOLING FAN CONTROL : System Description" for cooling fan operation.
Crankshaft Position SensorINFOID:0000000012431277
The crankshaft position sensor is located on the cylinder block rear
housing facing the gear teeth (cogs) of the signal plate at end of the
crankshaft. It detects the fluctuation of the engine revolution.
The sensor consists of a permanent magnet and Hall IC.
When the engine is running, the high and low parts of the teeth
cause the gap with the sensor to change.
The changing gap causes the magnetic field near the sensor to
change.
Due to the changing magnetic field, the voltage from the sensor
changes.
The ECM receives the voltage signal and detects the fluctuation of
the engine revolution.
ECM receives the signals as shown in the figure.
ECMINFOID:0000000012431278
The ECM consists of a microcomputer and connectors for signal
input and output and for power supply. The ECM controls the engine.

Refrigerant Pressure SensorINFOID:0000000012431299
The refrigerant pressure sensor is installed at the c
ondenser 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.
Stop Lamp Switch & ASCD Brake SwitchINFOID:0000000012431300
Stop lamp switch and ASCD brake switch are installed to brake pedal bracket.
ECM detects the state of the brake pedal by those two types of input (ON/OFF signal).
Throttle Control MotorINFOID:0000000012431301
The throttle control motor is operated by the ECM and it opens and closes the throttle valve.
The current opening angle of the throttle valve is detected by the throttle position sensor and it provides feed-
back to the ECM to control the throttle valve in response to driving conditions via the throttle control motor.
Throttle Control Motor RelayINFOID:0000000012431302
Power supply for the throttle control motor is provided to the ECM via throttle control motor relay. The throttle
control motor relay is ON/OFF controlled by the ECM. When the ignition switch is turned ON, the ECM sends
an ON signal to throttle control motor relay and batte ry voltage is provided to the ECM. When the ignition
switch is turned OFF, the ECM sends an OFF signal to throttle control motor relay and battery voltage is not
provided to the ECM.
Throttle Position SensorINFOID:0000000012431303
Electric throttle control actuator consists of throttle control motor,
throttle position sensor, etc. The throttle position sensor responds to
the throttle valve movement.
The throttle position sensor has two sensors. These sensors are a
kind of potentiometer which transform the throttle valve position into
output voltage, and emit the voltage signals to the ECM. The ECM
judges the current opening angle of the throttle valve from these sig-
nals and controls the throttle valve in response to driving conditions
via the throttle control motor.
ASCD Steering SwitchINFOID:0000000012431304
ASCD steering switch has variant values of electrical resistance for each button. ECM reads voltage variation
of switch, and determines which button is operated.

CAN COMMUNICATION
CAN COMMUNICATION : System DescriptionINFOID:0000000012431315
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 s
peed 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 CA N 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-30, "
CAN COMMUNICATION SYSTEM : CAN Communication Signal Chart", about CAN com-
munication for detail.
