1. WIPER AND WASHER SYSTEM
1) AUTO Washer Coupled Wiper Function
If you press the AUTO washer switch briefly with the ignition key ON and INT-AUTO switch "OFF", the
washer motor is operated for about 2 seconds to spray washer fluid once after the switch is turned ON
and the wiper relay is turned ON for 4 cycles. After that, the washer motor is operated for about 2
seconds to spray the washer fluid again and the relay is turned ON for 3 cycles and then the relay is
turned OFF.
2) Rear Washer Fluid Supply System
The front washer fluid reservoir supplies the rear washer fluid without additional washer fluid reservoir. Operating part for rear

(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.

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 return to the “OFF
"
position and turn off the 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.

(2) Power-up reminder wiper

08-277810-00
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.

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.

G-sensor(4WD, ABS)
For the vehicle with the ABS, a speed difference
between the wheels is not noticeable as all the
wheels are slipping during abrupt braking.
Therefore, the vehicle needs the speed information
from other sensors other than the wheel speed
sensor. The longitudinal acceleration sensor (G-
sensor) is used for this case. It controls the ABS by
using the signals from the sensor during abrupt
braking and acceleration.
TCU unit
The transmission control unit (TCU) is installed under
the driver seat, and controls the transmission. The
TCU is operated by the ignition power supply and
receives and processes the following information from
the inner sensors through CAN buses.E-coupling unit
The E-coupling unit is a control unit which
determines the magnetic force by
considering CAN signals (wheel speed,
engine torque, pedal opening, ABS/ESP
CAN signals, etc.) from other ECUs.
TGS Lever assembly
The TGS communicates with TCU
(Transmission Control Unit), ECU,
ESP HECU and instrument cluster
to let the driver select the desired
transmission gear and to maintain
the desired driving condition. Also,
the tip switch is installed on the
lever knob and the steering wheel
so that the driver select the gear
manually when the shift lever is in
"M".Sensor cluster
The sensor cluster is linked to
the sensors on the unit board
and CAN interface. And they
are housed in one case and
mounted to the body.

Steering gear box assembly
The steering gear box assembly consists of power cylinder and control valve. The power cylinder has a
cylinder, piston and piston rod. The control valve directs the oil to one end face of the piston to enhance
the steering force. There is a safety check valve which lets the driver steer manually when there is a
malfunction in the hydraulic circuit.
8. STEERING SYSTEM LAYOUT
1) HPS (Hydraulic Power Steering)
The hydraulic pump is a vane
type pump and consists of the
flow control valve and pressure
relief valve.The oil reservoir sends the oil to
the power steering pump and
receives the oil from the power
steering gear.There is a shock absorber which
is folded in the axial direction
when the vehicle is crashed and
a ignition switch assembly on
the column shaft.
The lower shaft minimizes the
torque change using a CV joint
which has constant angular
speed.

5. TRANSAXLE ELECTRONIC CONTROL SYSTEM
1) General Information
The transmission control unit (TCU) and its input/output network control the following transmission
operations:
Shift timing
Line pressure
Clutch pressure (shift feel)
Torque converter clutch -
-
-
-
also uses these signals when determining transaxle operating strategy. Using all of these input signals,
the TCU can determine when the time and conditions are right for a shift, or when to apply or release the
torque converter clutch. It will also determine the pressure needed to optimise shift feel. To accomplish
this, the TCU operates six variable bleed control solenoids and four on/off solenoids to control transaxle
operation.
2) TCU (Transmission Control Unit)
The transaxle control unit (TCU) is mounted
under the driver's seat and controls the operation
of the transaxle.
The TCU is activated and deactivated by the
ignition power supply and is connected to the
transaxle link harness by a 26 pin connector. The
TCU processes information received from internal
sensors and signals received across the CAN
bus in analogue and digital forms such as:
Transaxle input speed
Transaxle output speed
Accelerator pedal position
Gear selector position
Engine torque
Engine speed
Transaxle fluid temperature
Brake pedal status
Engine oil temperature
Engine coolant temperature
Ambient air temperature
