2012 SSANGYONG KORANDO engine

11-210000-00
Circuit description ▶
When compared to the vehicle equipped with ABS/EBD only, the internal hydraulic circuit has a
normally-open separation valve and a shuttle valve in primary circuit and in secondary circuit.
When the vehicle brakes are not applied during engine running or when applying the non-ABS operating
brakes, the normally-open separation valve and the inlet valve are open, whereas the normally-closed
shuttle valve and the outlet valve are closed.
When the ESP system is operating, the normally-open separation valve will be closed by the solenoid
valve operation and the hydraulic circuit will be established by the shuttle valve. Then, the inlet and outlet
valves will be closed or open depending on the braking pressure RISE, HOLD or DUMP conditions.
Flashing warning lamp and warning sound during ESP operation ▶
When the ESP operates while the vehicle is moving, the ESP warning lamp on the instrument panel
flickers and the buzzer sounds at every 0.1 second. The ESP lamp operation is to inform a driver that the
vehicle is extremely unstable.
The ESP system is just a supplementary system for the vehicle and it cannot control the vehicle over the
physical limit. Do not solely rely on the system but be advised to drive the vehicle safely.
Drive feeling during ESP operation ▶
When the ESP system activates, the driving feeling can be different depending on vehicle driving
conditions. For example, it will feel different when the ESP system is activated while the ABS is operated
by depressing the brake pedal and when the ESP system is in control without the brake pedal
depressed on the same curve.
If the ESP system operates with the brake applied, the brake pressure will be increased on the
corresponding wheel which already has braking pressure for the ESP controls. In other words, the ESP
system would make the driver feel more abruptly braked compared to the situation that the braking
pressure is applied to wheel which had no braking force.
Noise and vibration that driver senses during ESP operation ▶
The ESP system may transfer noise and vibration to a driver due to the pressure changes caused by the
motor and valve operations in a very short period of time.
Extreme cornering will trigger the ESP operation and this will make the driver sense noise and vibration
due to sudden brake application.
Also, the ESP system controls the engine power. Therefore, the driver may notice the engine power
decreases even when the accelerator pedal is depressed.

1. OVERVIEW
The electric power steering, EPS, does not have any belt-driven steering pump constantly running, so it
is lightweight and the motor consumes energy only when the steering wheel is turned by the driver, and
this leads to improvement in fuel efficiency. Also, the elimination of a belt-driven pump and its
accessories greatly simplifies manufacturing and maintenance. While offering these benefits, as it does
not contain any steering oil, the environment is not polluted both when the steering system is produced
and discarded.
In other words, the electric power steering (EPS) system uses the electric motor to assist the steering
force. It functions independently regardless of whether the engine is running or not, unlike the existing
hydraulic power steering.
The EPS system generates an assist steering force variably depending on the driving conditions by
controlling the motor's operation, based on the input signals from the sensors such as torque sensor and
angle sensor. In turn, the EPS receives the torque signal by the driver's movements of the steering
wheel, as well as the vehicle speed, and uses the motor to determine the assist torque. The EPS
controls the motor for this. Another features of EPS are fail-safe function, diagnosis function,
communication function between units and interface function for external diagnostic device.
The EPS system components such as the torque sensor, steering angle sensor, fail-safe relay, etc. are
located in the steering column and EPS unit assembly.
Advantages: ▶
Assurance of improved steering
Provides optimal steering force according to the
vehicle speed

The front sub frame consists of 4 body bush mountings(A) and 2 engine bush mountings(B) which
reduce the vibration from the powertrain and road, and also control the torque. And the two engine bush
mountings consist of an engine mounting which supports the engine powertrain and a transmission
mounting.
The engine side and transmission side mountings are rubber mountings with brackets and insulators
while the body mounting is a rubber bush mounting which is fitted to the frame.
Installation of front sub
frame (4WD)The installation of the front sub frame is the same for both automatic
transmission and manual transmission. For 4WD, the PTU and the
propeller shaft are installed.

C. General Warnings for Air Bag
Do not check the circuits with a circuit tester. Do not attempt to modify any air bag component
including the steering wheel, air bag mountings and related wirings.
Do not subject any air bag component, such as the steering wheel, air bag mountings, wirings, to
impacts. You might get severely injured by sudden deployment of the air bag.
As the air bag/seat belt pretensioner parts are very hot after being deployed. Allow them to cool
down sufficiently before touching them.
The deployed air bag/seat belt pretensioner cannot deploy again. It will work when an additional
impact is applied. The components of the deployed air bag/seat belt pretensioner are non-reusable
parts. Therefore, remove or replace them as a unit.
The air bag and seat belt pretensioner systems contain explosive charges, so handle carefully when
disposing or replacing them.
Incorrect inspection can result in serious injuries or malfunctions in the air bag and seat belt
pretensioner system.
The air bag warning lamp is illuminated for 3 to 7 sec. after the engine is started to check the system.
Drive the vehicle after this warning lamp is turned off. If this warning lamp stays ON, the system may
be defective. Have the air bag system checked immediately by Ssangyong Dealer or Ssangyong
Authorized Service Center. -

2. WARNINGS FOR POWER SEAT
Adjust the driver's seat before driving.
Make sure that the seat is firmly secured after adjusting.
Never drive the vehicle with the head restraint removed or lowered excessively. Otherwise, you
r
neck, spine or other parts of the body can be severely injured in the event of an accident.
If you recline the seatback excessively, you could slide under the seat belt and be injured severely
in a collision.
Do not put any object that could damage the seat on the seat.
The front and rear seats are equipped with the heated wire (seat warmer) system. Using the seat
warmer system excessively may cause minor burns. The following occupants should exercise
special care when using the heated wire seat. ▷
▷
▷
▷
▷
▷
Infant, child, old or handicapped person
Person with sensitive skin
Exhausted person
Persons who is drunk or took medicine which causes drowsiness such as sleeping pills, cold
tablets, etc. -
-
-
-
Do not place anything on the seat that insulates against the heat, such as a blanket or cushion.
Make sure that the head restraints are in place and secured properly. Never drive the vehicle with
the head restraint removed.
To minimize the injuries in a collision or an abrupt stop, make sure the seatback is in the upright
position before driving. If the seatback is reclined too much, the occupant could slide under the seat
belt in a collision or an abrupt stop and cannot be protected properly by the airbag system. ▷

3. CAUTIONS FOR POWER SEAT
You can operate the power seat with the ignition switch OFF. However, frequent operation of the
seat switch with the engine stopped can result in battery becoming discharged.
Operating more than one seat adjustment switch at the same time can cause damage to the seat
motor. Therefore, operate the seat switch only one at a time.
Do not use organic solvents such as benzene, thinner, alcohol or gasoline to prevent the seat cove
r
from being damaged while cleaning.
Do not operate the seat position adjustment switch forcefully when the seat does not move or it
contacts an object.
If the power seat is not operated, check and correct the problem before driving off. ▷
