For the vehicles without rain sensor, the BCM operates the wiper as follows:
When turning the ignition switch to ON from OFF position with the intermittent wiper switch in "ON"
position, the wipers do not operate.
When turning the wiper switch to ON from OFF position after turning the ignition switch to ON position,
the wipers operate one cycle.
The wiper's operation cycle depends on the vehicle speed (CAN communication with instrument
cluster) and wiping speed the side fascia panel.

2. CAUTIONS
Sensor Cannot Detect ▶
When the sensor is frozen (operate normally when it's thawed)
When the sensor is covered with foreign materials such as snow or condensation
(if the foreign materials are removed, the sensor operates normally.) -
-
Not defective but improperly working ▶
When the sensing portion is frozen (operates normally after thawed)
When reversing on rough roads, gravel roads, hills, or grass.
When receiving other ultrasonic signals (metal sounds or air braking noises from heavy
commercial vehicles).
When there is heavy rainfall or water drops.
When the sensor is covered with snow. -
-
-
-
-
Certain obstacles that sensors cannot detect ▶
Thin and narrow objects, such as wires, ropes, or chains
Cotton, sponge, clothes, snow that absorb ultrasonic waves. -
-
Weak Sensing Scopes ▶
When the ambient temperature is too high or too low.
When a 1 m or less long small object with a diagmeter of 100 mm or less is detected. -

IP display (SVC only)
When the gear selector lever is shifted into “R", the parking aid system is activated and three
sensors in the rear bumper detect the distance to any obstacle. The PAS detects the returning signals
reflected to the obstacles at regular intervals when the vehicle is parked to indicate the display and alarm
for the distance between the obstacles by phase so as to allow the driver easy parking by securing safe
distance.

While reversing, if obstacles are within stage 1, the warning beep sounds with long intervals. If within
stage 2, the warning beep sounds with short intervals and if within stage 3, the warning beep sounds
continuously.
Sensor detection range

The ultrasonic sensors transmit ultrasonic waves
and receive the reflected waves from an obstacle
to detect it in the following order: L → C → R.

4. OUTPUT SPECIFICATIONS FOR SENSOR SELF-
DIAGNOSIS BUZZER SOUND
Fail condition (However, no obstacle should be within 30 cm)
1. The signal wire is open
2. The power wire (+ and -)is open -Conditions to "FAIL" in sensor diagnosis ▶Buzzer interval during self diagnosis ▶
Timeout processing time for buzzer interval after measuring distance/self diagnosis: 600 ms
- If timeout is reached, the PAS returns to undetected condition.
Process while re-inputting
- After timeout, the process is performed normally if the signal required for display is received
from beginning to end. (not detectable if the signal is received in the midst of process) 1.
2.Exception/error handling ▶ Self diagnosis is performed once when the ignition is switched on (gear shift lever in "R" position). If the
system is defective (Fail) due to open sensor or communication problem, the information for the failed
sensor is displayed as buzzer sound.
If it is normal, the warning buzzer sounds for 60 ms.

Fuse for vehicle with EPS
The vehicle with EPS has EPS fuse (80A)
mounted to the positive (+) terminal of the
battery not in the fuse box.
EPS unit
The ECU controls the electric power
steering system depending on the driving
conditions, based on the signals from the
torque and angle sensor.
HECU (Hydraulic & Electronic Control Unit)
HECU for ABS HECU for EPS
The HECU (Hydraulic & Electronic Control Unit) determines the slip conditions of vehicle wheels by
calculating each wheel's speed and the increment/decrement of speed based on the information
detected by the sensors, and controls the pumping and boosting/reducing/keeping pressure by
operating the valve and motor of HECU.

Steering wheel angle sensor (SWAS)
The steering wheel angle sensor is mounted between
the steering column and the steering column shaft. It is
commonly used by the ESP (Electronic Stability
Program) system. And it receives signals of the steering
wheel angle sensor from the ESP HECU (Hydraulic &
Electronic Control Unit).
