SsangYong Korando III (2010 year). Manual - part 229

07-4

1. OVERVIEW

The AWD system in this vehicle is the electronic 4WD system and controls the traction to rear wheels 

according to the driving conditions.

1) Driving Mode

(1) AUTO mode (Normal driving mode)

Normally the vehicle is in 2WD mode. 

Automatically change to this mode when the vehicle needs higher traction.

(2) LOCK mode (when pressing 4WD LOCK switch)

This mode provides the highest traction. Use 

this mode when driving on unpaved, rugged, 

steep, sandy, wet or slippery roads.

In 4WD LOCK mode, if the rear wheel speed 

exceeds 40 km/h, 4WD LOCK mode is 

canceled and 4WD AUTO mode is activated 

(Indicator OFF). If the speed is decreased 

below 35 km/h, 4WD LOCK mode is resumed 

(Indicator ON again).

2. SYSTEM LAYOUT

1) Components

(1) PTU (Power Transfer Unit)

The power transfer unit in the front wheel drive model changes the angle of engine torque to 90° 

and transfer it to E-coupling to distribute the torque to rear wheels.

(2) E-Coupling (Electronic Coupling)

E-Coupling transfer the engine torque from PTU to rear axle and controls to distribute it between front 

wheels and rear wheels.

(3) E-Coupling Control Unit (ECU)

E-Coupling controls the current (clutch engagement force) of EMCD in E-Coupling according to CAN 

signals (wheel speed, engine torque, pedal position, ABS/ESP signals).
