2. SYSTEM OVERVIEW
1) Terms and Definition
CBS: Conventional Brake System
ABS: Anti-Lock Brake System
EBD: Electronic brake-Force Distribution
ESP: Electronic Stability Program
ABD: Automatic Braking Differential
ASR: Acceleration Slip Regulation
AYC: Active Yaw Control (Understeer and Oversteer Control)
HBA: Hydraulic Brake Assistant
ARP: Active Rollover Protection
HSA: Hill Start Assistant
Brake pad: Brake pad is a component of disk brakes used in automotive and other
applications. Brake pad is steel backing plates with friction material bound to the surface that
faces the brake disc.
Brake disc: The brake disc is a device for slowing or stopping the rotation of a wheel while it is
in motion.
Brake caliper: To stop the wheel, friction material in the form of brake pads (mounted on a
device called a brake caliper) is forced hydraulically against both sides of the disc. Friction
causes the disc and attached wheel to slow or stop.
Brake master cylinder: The brake master cylinder is a control device that converts non-
hydraulic pressure (commonly from a driver's foot) into hydraulic pressure, in order to move
other device(s) which are located at the other end of the hydraulic system, such as one or
more slave cylinders. As piston(s) move along the bore of the master cylinder, this movement
is transferred through the hydraulic fluid, to result in a movement of the slave cylinder(s). The
hydraulic pressure created by moving a piston (inside the bore of the master cylinder) toward
the slave cylinder(s) compresses the fluid evenly, but by varying the comparative surface-area
of the master cylinder and/or each slave cylinder, one will vary the amount of force and
displacement applied to each slave cylinder (relative to the amount of force and displacement
that was applied to the master cylinder). -

2) Functions

2) Operation of ESP System
The ESP (Electronic Stability Program) has been developed to help a driver avoid danger of losing
control of the vehicle stability due to understeer or oversteer during cornering. The yaw rate
sensor, lateral sensor and longitudinal sensor in the sensor cluster and the steering wheel angle
sensor under the steering column detect the vehicle conditions when the inner or outer wheels are
spinning during oversteer, understeer or cornering. The ESP ECU controls against oversteer or
understeer during cornering by controlling the vehicle stability using input values from these
sensors and applying the braking force to the corresponding wheels independently. The system
also controls the engine power right before the wheel spin synchronized with the ASR function to
decelerate the vehicle automatically in order to maintain the vehicle stable during cornering.
(1) Under steering
What is understeering? ▶
Understeer is a term for a condition in which the steering wheel is steered to a certain angle during
driving and the front tires slip toward the reverse direction of the desired direction. Generally,
vehicles are designed to have understeer. It is because that the vehicle can return back to inside of
cornering line when the steering wheel is steered toward the inside even when the front wheels are
slipped outward.
As the centrifugal force increases, the tires can easily lose the traction and the vehicle tends to slip
outward when the curve angle gets bigger and the speed increases.

11-14
ESP controls during understeer ▶
The ESP system recognizes the directional angle with the steering wheel angle sensor and senses
the slipping route that occurs reversely against the vehicle cornering direction during understeer
with the yaw rate sensor and lateral sensor. Then, the ESP system applies the braking force to the
rear inner wheel to compensate the yaw moment value. In this way, the vehicle does not lose its
driving direction and the driver can steer the vehicle as intended.
(2) Over steering
What is oversteering? ▶
Oversteer is a term of a condition in which the steering wheel is steered to a certain angle during
driving and the rear tires slip outward losing traction.
Compared to understeering vehicles, it is hard to control the vehicle during cornering and the
vehicle can spin due to rear wheel moment when the rear tires lose traction and the vehicle speed
increases.
ESP controls during oversteer ▶
The ESP system recognizes the directional angle with the steering wheel angle sensor and
senses the slipping route that occurs towards the vehicle cornering direction during oversteer
with the yaw rate sensor and lateral sensor. Then the ESP system applies the braking force to the
front outer wheel to compensate the yaw moment value. In this way, the vehicle does not lose its
driving direction and the driver can steer the vehicle as intended.

▶ Step 6
To enter the step 6 from 5, turn the fan speed dial lightly toward the right not using the
temperature control dial. In this step, you can decrease or increase by up to 3 degrees
from the temperature set on the A/C controller. -You can check that the temperature value from each temperature sensor is displayed
properly in this step. Pressing the defroster switch changes the temperature value that
appears on the display in the order as follows: -
2) Self-diagnosis step
(1) Step 1
Turn the ignition ON and press the OFF switch for 5 sec. or more within 10 sec.
Then the first step of the self-diagnosis is started as shown in the below figure.
2. Display for checking VFD and all LED segments
1. Press OFF switch for 5 sec. or more

(2) Step 2
The sensors and air mix door are checked for proper operation in this step. When the step 2 is
started, the number "2", which indicates that the system is in the step 2, apprears on the display
and the check for sensors is performed. Once the check is done (for 10 to 20 sec.), the one digit
number between 0 and 8 is added behind "2". "20" means there is no fault code. For the meaning
of the rest of the numbers, refer to the description below.
1. Turn temperature dial lightly toward right to enter step 2

If "-" is displayed before "2", it means
that the sensor for that flashing fault
code has a short circuit.

(3) Step 3
In this step, you can check the position and condition of the air source door and mode door. To
start step 3, turn the temperature control dial lightly toward the right and confirm that the number 3
appears on the display. It takes several tens of seconds to finish the check. If there is no fault
code, "30" is displayed. And if there is a malfunction, the corresponding fault code is added as
described in the step 2.
Turn temperature dial lightly toward
right to enter step 3 1.
