RAIN SENSOR
6. RAIN SENSOR RELATED CIRCUIT
The rain sensor has one connector with 4 pins and each pin has following function as shown in
the circuit diagram.
However, in this vehicle, the terminal No. 1 and No. 2 are for communications between STICS
and the rain sensor; the No. 1 terminal sends the detected value from the rain sensor to STICS
then the STICS drives wiper motor.
to the rain sensor to recognize whether it is actual rain or it is in rain sensing wiper operation
mode.
No.2 terminal sends the wiper and washer operation information such as
washer operation mode,
MIST mode, or
AUTO wiper position -

1. COMPONENT SPECIFICATIONS OF PARKING AID
SYSTEM
The parking aid system emits the supersonic wave signals from the sensors on the rear bumper
with a specific interval and detects the reflected signals from obstacles while the gear selecto
r
lever is in “R” position.
The number of displaying bars is decreased and the alarm interval becomes faster as the
obstacle approaches. This supplementary system is to secure the safety distance for parking.

Detecting type: Super sonic wave
Detecting distance: 25 ~ 120 cm
(distance between sensor and obstacle)

while watching DVD or VCD, the rearview appears on
the front monitor.
When moving the gear selector lever into “R”
position, the alarm buzzer in ICM box sounds (installed
at bottom of STICS).
Parking aid sensor(Rear bumper)
The three parking aid sensors send the distance data
between rear bumper and obstacle to PAS unit.
Rearview camera
The rearview camera sends the rearview to the monitor
by using wide angle lens.
PAS unit
It is a control unit for the parking aid system (PAS) and
transmits the signals from sensors to multimeter and
buzzer.(installed in tuner/amplifier bracket)

3. OPERATIONS OF PARKING AID SYSTEM(PAS)
1) Alarm interval
Alarm interval and display changes according to the distance as below:
While reversing, if obstacles are within stage 1, the warning beep sounds with long intervals. I
f
within stage 2, the warning beep sounds with short intervals and if within stage 3, the warning
beep sounds continuously.
2) System Trouble Shooting
When the power is applied (gear selector lever is in “R” position), the sensor will be
diagnosed once. If found any failure due to open circuit to sensor or communication error,
warning buzzer sounds for 3 seconds and the data on failed sensor transmits to the instrument
panel to light up the corresponding LED. If normal, the warning buzzer sounds only for 65 ms.
1) Whenever the power is applied, the diagnosis mode is initiated.
2) Sensor failure conditions
(conditions for warning beep due to failure)
(a) Open in sending circuit
(b) Open in receiving circuit
(c) Open in power circuit (+, -)

3) Cautions on parking aid system
Note that the display does not show everything in the rear area.
Always check nobody, especially animals and children, is behind the vehicle.
Normal precautions when reversing should be maintained. *
*
The parking aid system is just a supplemental device to help your parking operation.
Always keep the safety precautions.
Do not press or shock the sensors by hitting or high-pressure water gun while washing, o
r
the sensors will be damaged.
If the system is in normal operating conditions, a short beep sounds when the gear selecto
r
lever is moved into “R” position with the ignition key “ON”.
If the system is in abnormal operating conditions, a beep sounds for 3 seconds when the
gear selector lever is moved into “R” position with the ignition key “ON” or engine
running. However, it is also occurred when the obstacle is within 50 cm from the rea
r
bumper. 1.

(1) The parking aid system will not work or improperly work under
following cases:
▶Certain obstacles that sensors can not detect
- Wires, ropes, chains.
- Cotton, sponge, clothes, snow that absorb ultrasonic waves.
- Obstacles lower than the bumper.
▶Not defective but improperly working
- When the sensing portion is frozen.
- When the sensing portion is covered by rain, water drops, snow or mud.
- When receiving other ultrasonic signals
(metal sound or air braking noises from heavy commercial vehicles).
- When a high-power radio is turned on.
▶Narrowed sensing area
- When the sensing portion is partially covered by snow or mud.

▶Not defective but may occur improper working
- When driving on the rough road, gravel road, hill and grass.
- When the bumper height is changed due to the heavy load.
- When the sensing portion is frozen.
- When the sensing portion is covered by rain, water drops, snow or mud.
- When receiving other ultrasonic signals
(metal sound or air braking noises from heavy commercial vehicles).
- When a high-power radio is turned on.
- When some accessories are attached in detecting ranges

4. SENSORS AND ACTUATORS
1) Sun Sensor
It is installed on the upper left end of instrument panel. It is using characteristics that the
amount of current changes according to amount of light on the photosensitive surface. Photo
diode, converts the changes in light intensity into electrical changes, detects the amount of light
coming through windshield and changes it into current and then sends the signal to FATC
controller.
(1) Inspection
Remove the sun sensor and measure the current between terminals under sunlight.
Measure the current again under shade. It is in normal conditions if the measured value is
less than the measured value under sunlight.
Turn the ignition switch to “ON” position.
Measure the voltage to the sun sensor from FATC connector. (approx. 2.5 V under sunlight
and 4.8 V under shade.)
If the voltage value cannot be measured, check the circuit for open. If the measured value is
within the specified range, replace the FATC controller. 1.

2) Active Incar/Humidity Sensor (AIH Sensor)
The AIH sensor is installed at the driver side instrument panel undercover. It is a sensor that
detects interior temperature and humidity.
(1) Location
(2) Functions
Interior temperature sensor
▶
This sensor is a negative temperature coefficient (NTC) thermistor and detects the interio
r
temperature with air coming from senor hole and then sends the voltage value according to the
changed resistance to FATC controller.
Humidity sensor
▶
This sensor detects the interior humidity with humidity cell and then sends the voltage value
according to the changed humidity to FATC controller.
