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).

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.
2.

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.
