5. SYSTEM DESCRIPTION
1) Block Diagram of ESP HECU

11-230000-00
2) DUMP (ESP is working) Mode
The pressure decreases just before the wheel speed drops and the wheels are locked.
The inlet valve closes and the outlet valve opens as in the ABS HECU and the oil is gathered at the low
pressure chamber while no additional oil is being supplied. Then the pump operates to allow fast oil
drainage. The shuttle valve and the separation valve do not operate while decompression.

11-250000-00
4) RISE (ESP is working) Mode
The shuttle valve and inlet valve will be open and the separation valve and outlet valve will be closed.
Then, the pump is operated. When ESP operates while the ABS is operating, the pressure will be
increased continuously until just before the corresponding wheel gets locked.

5) Hydraulic Circuit 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 will stay closed. When the wheel starts to lock, the HBA
function cancels and switches to ABS operation.

2. OPERATING PROCESS
1) Sunroof Switch
This can be closed or open manually to block sunlight when the sunroof function is not in use. The sunroof glass can be open in two steps and can be tilted by the switch operation. The sunroof switches are included in the overhead console switches and consists of the TILT,
CLOSE and OPEN switches.
