▶Hydraulic Diagram of HBA
The above figure shows one front and one rear wheel and the same hydraulic circuit forms as
in the ESP operation.
When HECU recognizes that it is an emergency and it is required for hard braking, depending
on the pressure value of the brake pressure sensor and pressure changes caused by the
pressure sensor timing, it operates the pump immediately to apply the brake pressure at the
wheels.
Then, the pressure in the pump increases until just before the corresponding wheel gets locked.
The motor still keeps rotating and the outlet valve and the separation valve are will stay closed.
When the wheel starts to lock, the HBA function cancels and switches to ABS operation.

2) HYDRAULIC CIRCUIT DIAGRAM
(1) Hydraulic Circuit of ABS
The vehicle equipped only with the ABS controls the wheel’s braking force using three 3-
channel 4-sensor method. The front wheels that are the primary circuit of the brake system is
composed of two wheel speed sensors and two channel valves system with two inlet valves
and two outlet valves. The rear wheels that are the secondary circuit of the brake system is
composed of two wheel speed sensors, one inlet valve and one outlet valve. This system is
similar to the one from the previous model.

(2) Rain Sensor Coupled Wiper
If equipped with RE-STICS rain sensor, has following operation system.
System layout ▶
This vehicle has a different wiper control logic compared to other models. As shown in the
system diagram, the rain sensor unit does not control wiper directly. The rain sensor unit sends
infrared rays signal through LED and then receives it with photo diode and then sends the
returned signal to STICS and the STICS controls the wipers directly.
For more details, refer to rain sensing wiper section in this manual.

3) Fuel Level Gauge
The fuel level gauge displays the resistance value of the float on the fuel sender in the fuel tank
through a pointer. Note that this vehicle doesn’t have a service hole for checking the fuel
sender connector in the fuel tank.
The fuel sender and its connector can be checked and replaced only when the fuel tank is
removed. The power supply and resistance value should be measured at the connector in front
of the fuel sender (refer to wiring diagram).
When the power supply and output resistance are normal, the float operation by fuel level may
be defective; if so, replace the fuel sender.
Tolerance and resistance value by indicating angle
This table shows the tolerance and resistance value changes by fuel level in normal conditions.
Therefore, the differences that can be occurred by the road conditions and fuel fluctuations are
ignored.

6. RAIN SENSOR RELATED CIRCUIT
The rain sensor has one connector with 4 pins and each pin has following function as shown in
the circuit diagram.
However, in this vehicle, the terminal No. 1 and No. 2 are for communications between STICS
and the rain sensor; the No. 1 terminal sends the detected value from the rain sensor to STICS
then the STICS drives wiper motor.
to the rain sensor to recognize whether it is actual rain or it is in rain sensing wiper operation
mode.
No.2 terminal sends the wiper and washer operation information such as
washer operation mode,
MIST mode, or
AUTO wiper position -
