ABS SYSTEM
3. ON-VEHICLE SERVICE
(1) Electronic system service precautions
Take care to avoid electronic brake control module (HECU) circuit overloading. In testing for
opens or shorts, do not ground or apply voltage to any circuit unless instructed to do so by the
diagnostic procedure. Test circuits only with a high-impedance multi-meter. Never remove o
r
apply power to any control module with the ignition switch in the ON position. Always turn the
ignition to the OFF position before removing or connecting battery cables, fuses or connectors.
(2) General service precautions
Disconnect the HECU connector before performing any vehicle welding work using an electric
arc welder. Do not attempt to disassemble any component designated as nonserviceable. The
hydraulic modulator and the HECU can be seperated. (There is however no access to repai
r
the each components.)
(3) Bleeding system
Replacement modulators are shipped already filled and bled. In normal procedures requiring
removal of the modulator, such as to replace the HECU, air will not enter the modulator, and
normal bleeding will be all that is needed.
If air enters the hydraulic modulator, or if an unfilled modulator is installed, use the brake
bleeding program in the scan tool to bleed the modulator. Manual bleeding of the hydraulic
modulator is not possible.
1) Service Precautions
Brake Fluid may irritate eyes and skin. In case of contact, take the following actions:
Eye contact - rinse thoroughly with water.
Skin contact - wash with soap and water.
Ingestion - consult a physician immediately. -
-
-
To help avoid personal injury due to poor braking. DO NOT Tap into the vehicle’s
brake system to operate a trailer brake system.
When fasteners are removed, always reinstall them at the same location from which they
were removed. If a fastener needs to be replaced, use the correct part number fastener
for is not available, a fastener of equal size and strength (or stronger) may be used.
Fasteners that are not reused, and those requiring thread-locking compound will be
called out. The correct torque values must be used when installing fasteners that require
them. If the above procedures are not followed, parts or system damage could result.

(2) ABS Circuit Per ABS Operation Range
Hydraulic Pressure Circuit when ABS is Not Operating ▶
No Hydraulic Pressure Circuit when ABS is Operating ▶
The hydraulic pressure in the master cylinder increases through the vacuum booster and it is
delivered to the wheel via the normal open inlet valve. At this moment, the normally-closed
outlet valve is closed. The speed of the wheel that hydraulic pressure is delivered reduces
gradually
As hydraulic pressure on each wheel increases, the wheel tends to lock. In order to prevent the
wheel from locking, the hydraulic valve modulator operates the inlet valve control solenoid to
close the inlet valve and stop the hydraulic pressure increases. At this moment, the outlet valve
is closed. This procedure helps the wheel to maintain a stable hydraulic pressure.

ABS SYSTEM
Pressure Decreases in the Circuit when ABS is Operating ▶
Pressure Increases in the Circuit when ABS is Operating ▶
Even when the hydraulic pressure on each circuit is stable, the wheel can be locked as the
wheel speed decreases. This is when the ABS ECU detects the wheel speed and the vehicle
speed and gives the optimized braking without locking the wheels. In order to prevent from
hydraulic pressure increases, the inlet valve is closed and the outlet valve is opened. Also, the
oil is sent to the low pressure changer and the wheel speed increases again. The ABS ECU
operates the pump to circulate the oil in the low pressure chamber to the master cylinder. This
may make the driver to feel the brake pedal vibration and some noises.
As the wheel speed increases, the inlet valve opens and the wheel’s pressure increases
due to the master cylinder pressure. The oil in the low pressure chamber circulates to the wheel
by the pump and the wheel speed decreases as the hydraulic pressure at wheel increases. This
operation continues repetitively until there are no signs that the ECU is locking the wheels.
When the ABS hydraulic pressure control takes place, there may be some vibration and noises
at the brake pedal.

POWER STEERING SYSTEM
3. POWER STEERING PUMP
The vane type pump that is connected to engine by belt is used for the power steering system.
This pump generates and controls a proper hydraulic pressure and flows by using the flow
control valve and pressure relief valve.
The flow control valve regulates the excessive amount of discharging oil. When the steering
wheel is stationary or the oil circuit is blocked, the pressure relief valve returns the ove
r
pressurized oil to the oil reservoir.
4. OIL RESERVOIR
The oil reservoir sends the oil to the power steering pump and receives the oil from the power
steering gear.
The oil level in the reservoir depends on the steering wheel positions. therefore, measure the oil
level when the steering wheel is positioned at straight ahead direction (neutral).

8710-01
The STICS in this vehicle has similar functions with the one used in the new Rexton. Additional
function of diagnosing through SCAN-Tool has been added into new STICS.
The major difference in hardware-wise is that STICS receives vehicle collision signal from G-
sensor in the airbag module to activate automatic door unlock function when the vehicle
collided over 15 km/h of vehicle speed.

2) Ignition Key Reminder
(1) Key Reminder Warning
The chime buzzer output in the ICM box continues when opening the driver’s door
while the ignition key is inserted into ignition switch.
When removing the ignition key or closing the driver’s door during chime buzzer output,
the output turns off.
This function is not available when the ignition switch is “ON”. 1.

(2) Key Reminder
This function does not work if the vehicle speed is over 3 km/h.
The system outputs “UNLOCK” for 5 seconds (T2) from 0.5 seconds after the driver’s
door is opened and the door lock switch is changed to “LOCK” (while the ignition key
is in ignition switch).
The system outputs “UNLOCK” for 5 seconds (T2) when the door lock switch is
changed to “LOCK” from “UNLOCK” and the driver’s door is closed within 0.5
seconds (T1) (while the ignition key is in ignition switch). 1.

(3) All Door Lock Prevention Function when a Door is Opened
1. When a door is opened, all doors should be unlocked for 5 seconds if inputs LOCK signal.
The LOCK signal means the central door locking (REKES, central door lock switch, knob
switch) except LOCK input by rear door knob.
After unlocking and opening only the driver’s door with remote control key under
armed mode (driver’s door is unlocked but passenger’s and rear doors are locked),
only the driver’s door generates unlock signal when trying to lock the driver’s door
with the driver’s door opened.
Above operations is regardless of key positions and have priority over the ignition key
reminder function. -
-
-
2. When the door is closed during unlock output for 5 seconds under item 1 condition, the
unlock
output stops.
All doors except tailgate and hood output “UNLOCK” for 5 seconds (T1) when the
“LOCK” signal is inputted (while the ignition key is removed and a of door is opened).
When the door is closed during unlock output for 5 seconds, the unlock output stops. -

7) Room Lamp Control
(1) Front Room Lamp
The front room lamp comes on when opening the
driver’s door or passenger’s door while the
front room lamp switch is at door coupled position
and the key reminder switch is turned off.
The room lamp stays on for 2 seconds (T1) and
then decays through 3 seconds (T2) when
closing the driver’s door or passenger’s door.
The room lamp output should stop immediately
after turning on the ignition key during decaying
operation.
The front room lamp comes on for 30 seconds
(T3) when receiving the unlock signal from the
remote control key while the door is closed. 1.

4.
The front room lamp output period is extended by 30 seconds (T3) when receiving the
unlock signal from the remote control key again during output.
When a door is opened during its extended period, the lamp stays on. If closed, operates as
in step 2.
