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.

The fuel filler cap warning lamp tunes OFF, according to any condition listed below:
• Reset operation is performed by operating the meter control switch on the combination meter. Refer to
MWI-
16, "Switch Name and Function".
- When the reset operation is performed, the combination meter transmits a fuel filler cap warning reset signal to ECM via CAN communication. ECM transmits a fuel filler cap warning display signal (request for display
OFF) to the combination meter via CAN communication. When receiving the signal, the combination meter
turns OFF the fuel filler cap warning display.
• EVAP leak diagnosis result is normal.
• Fuel refilled.
• DTC erased by using CONSULT.
NOTE:
MIL turns ON if a malfunction is detected in leak diagnosis results again at the trip after the fuel filler cap warn-
ing display turns ON/OFF.

*: This signal is sent to the ECM via the CAN communication line
BASIC ASCD SYSTEM
Automatic Speed Control Device (ASCD) allows a driver to keep vehicle at predetermined constant speed
without depressing accelerator pedal. Driver can be set the vehicle speed in the set speed range.
ECM controls throttle angle of electric thro ttle control actuator to regulate engine speed.
Operation status of ASCD is indicated in combination meter.
If any malfunction occurs in the ASCD system, it automatically deactivates the ASCD control.

DTC Inspection Priority ChartINFOID:0000000012431344
If some DTCs are displayed at the same time, perform inspections one by one based on the following priority
chart.
P060A
ECM NOTE:
Fail-safe may not occur depending on malfunction type.
• ECM stops the electric throttle control actuator control, throttle valve is maintained at a
fixed opening (Approx. 5 decrees) by the return spring.
• The position of the following commponents is fixed.
- Intake valve timing control solenoid valve
- Exhaust valve timing control solenoid valve
• Engine torque may be limited.
• ASCD operation may be deactivated.
P0643
ECM • ECM stops the electric throttle control actuator control, throttle valve is maintained at a
fixed opening (Approx. 5 decrees) by the return spring.
• The position of the following commponents is fixed.
- Intake valve timing control solenoid valve
- Exhaust valve timing control solenoid valve
P0643 Sensor power supply ECM stops the electric throttle control actuator control, throttle valve is maintained at a
fixed opening (approx. 5 degrees) by the return spring.
P1720 Vehicle speed sensor ECM operates active grille shutter to fully-open position.
P1805 Brake switch ECM controls the electric throttle control actuator by regulating the throttle opening to a
small range.
Therefore, acceleration will be poor.
Vehicle condition Driving condition
When engine is idling Normal
When accelerating Poor acceleration
P2100
P2103 Throttle control motor relay ECM stops the electric throttle control actuator control, throttle valve is maintained at a
fixed opening (approx. 5 degrees) by the return spring.
P2101 Electric throttle control function ECM stops the electric thro ttle control actuator control, throttle valve is maintained at a
fixed opening (approx. 5 degrees) by the return spring.
P2118 Throttle control motor ECM stops the electric throttle control actuator control, throttle valve is maintained at a
fixed opening (approx. 5 degrees) by the return spring.
P2119 Electric throttle control actuator (When electric throttle control actuator does not function properly due to the return sp ring
malfunction:)
ECM controls the electric throttle actuator by regulating the throttle opening around the
idle position. The engine speed will not rise more than 2,000 rpm.
(When throttle valve opening angle in fail safe mode is not in specified range:)
ECM controls the electric throttle control actuator by regulating the throttle opening to 20
degrees or less.
(When ECM detects the throttle valve is stuck open:)
While the vehicle is driving, it slows down gradually by fuel cut. After the vehicle stops, the
engine stalls.
The engine can restart in the Neutral position, and engine speed will not exceed 1,000 rpm
or more.
P2122
P2123
P2127
P2128
P2138 Accelerator pedal position sen-
sor
The ECM controls the electric throttle control actuator in regulating the throttle opening in
order for the idle position to be within +10 degrees.
The ECM regulates the opening speed of the throttle valve to be slower than the normal
condition.
So, the acceleration will be poor.
