(2) Wiper LO/HI control
The wiper LOW relay is turned on when the multifunction wiper switch is at the LO position. The wiper
HIGH relay is turned on when the wiper switch is at the HI position. When the wiper switch is at the HI
position, both the LOW relay (constant operation) and HIGH relay are operated.
The wiper motor returns to parking position and stops, even when turning off the ignition switch during
wiper operation.
The wiper relay should stay ON in low/high wiper operation mode even if the parking signal for the
wiper motor is not received. In INT/AUTO wiper operation mode, the wiper relay should be turned
OFF after 5 seconds if there is no parking signal for the wiper for 3 seconds and informs the driver of
parking position signal abnormality.
While the wiper operates at low/high speed, the front/rear washer switch can be operated but the auto
washer switch cannot.
The wiper motor returns to parking position and stops when turning off the ignition switch during wiper
operation in high mode. 1.

When the AUTO washer switch is operated with IGN ON and the INT/AUTO switch OFF, the
washer motor is operated for 2 sec. and the wiper continues to cycle 4 times. And then the washer
motor is operated for 2 sec. and the wiper continues to cycle 3 times before returning to park
position.
The auto washer switch signal is overridden during speed sensitive intermittent wiper, washer
coupled wiper or auto washer coupled wiper operation.
When turning the wiper switch to AUTO position during the operation of auto washer, the auto
washer stops its operation and the intermittent/automatic wiping mode will be started.
The front and rear washer switch signal are overridden during the operation of auto washer.
The input from the switch during the AUTO washer coupled wiper operation also is ignored. 1.

Auto washer switch
If pressing the switch when the wiper switch turns
to the "OFF" position, washer fluid is sprayed
once and wiper operates 4 times.
After a while, washer fluid is sprayed once more
and the wiper operates 3 times.

4) Rear Washer Control Function
The rear washer motor is operated only when the rear washer switch is activated with the ignition
key ON.
If the front washer or automatic washer switch signal is received during the rear washer switch
operation, the washer motor stops and the front washer or automatic washer motor begins to
operate. 1.
2.Rear washer motor control
When the switch is fully turned, washer fluid will be
sprayed onto the rear window glass and the wiper
will also operate. When the switch is released, it will
wiper and washer.

If the intermittent/automatic wiper switch is in "ON" position, the wiper motor does not operate even
when turning the ignition switch to ON from OFF position.
When the INT/AUTO wiper switch is turned on from off with the ignition switch ON, the wiper is
operated at low speed for the 1st cycle regardless of the rain sensor signals. After that, if the
INT/AUTO wiper switch is turned on from off, the wiper cycles one time at low speed only when the
rain sensor detects the presence of rain. 1.

When the wiper speed control switch is turned to step 3 from step 4 the wiper motor cycles one time
at low speed, provided that the BCM receives a communication error signal from the rain sensor uni
t
with IGN ON and the INT/AUTO switch ON. 2.
When the wiper speed control switch is turned to step 2 from step 3 the wiper motor cycles one
time at low speed, provided that the BCM receives a faulty sensor signal from the rain sensor unit
with IGN ON and the INT/AUTO switch ON. 1.

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.

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.

ECU
The ECU controls the electric
power steering system
depending on the driving
conditions, based on the
signals from the torque and
angle sensor.
2) EPS (Electric Power Steering)
Fuse
The vehicle with EPS has
EPS fuse (80A) mounted to
the positive (+) terminal of the
battery, and this fuse supplies
power to the EPS unit
directly..
Steering gear box assembly
When the driver turns the steering wheel, a torque is generated and the torque sensor and the steering
angle sensor in the EPS system detect the rotation of the steering column to run the electric motor. At
this time, the worm gear connected to the motor drives the helical gear mounted to the steering column
to generate the assist torque for the steering column. This allows the driver to operate the steering
wheel easier.

Colum shaft assembly
The column shaft assembly consists
of BLAC motor, ECU, torque and

steering (EPS) system uses the
electric motor to assist the steering
force. It functions independently
regardless of whether the engine is
running or not, unlike the existing
hydraulic power steering.
The lower shafts functions in the
same way as the hydraulic type.
