SsangYong Korando III (2010 year). Service manual — part 219

3. MODES AND FUNCTIONS

This allows the driver to define the highest
possible gear by selecting “+” or “-” on the
gear selector when the lever is in the “M”

position. When the lever is first moved to the
manual “M” position the transaxle will select

one lower gear than current gear.

When driving on a slippery road, push the tip switch forward into the "+" position in "M" position.

This causes the transaxle to shift into the 2nd gear which is better for smooth driving on a slippery

road.

1st Gear State

▶

The 1st gear state will display on the

instrument cluster. Unlike the normal 1st gear,

engine braking will be available in this manual

1st state.

-

2nd Gear State

▶

The 2nd gear state will display on the

instrument cluster. 2nd gear has engine braking

available.

-

3rd Gear State

▶

The 3rd gear state will display on the

instrument cluster. 3rd gear has engine

braking available.

-

4th Gear State

▶

The 4th gear state will display on the

instrument cluster. 4th gear has engine

braking available.

-

5th Gear State

▶

The 5th gear state will display on the

instrument cluster. 5th gear has engine

braking available.

-

6th Gear State

4. LIMP HOME MODE

When the transaxle is defective

▶

In the event of a system fault, the TCU also provides for failure mode effect control (FMEC) to maintain

maximum functional operation of the transaxle. (There are 3 FMEC modes, mechanical limp-home

mode, electrical limp-home mode, limp-home mode C.)

In the event of a total loss of control or electrical power, the basic transaxle functions (Park, Reverse,

Neutral and Drive) are retained. The 4th and reverse gear ratios with the torque converter clutch in the

unlocked state are the retained gear states the hydraulic system supports without any electrical

assistance. (Mechanical limp-home)

If the speed sensor circuit is failed, the gear is fixed to 4th gear, but manual shifting
(2nd↔3rd↔4th) is available.(Electrical limp home mode)

If the inhibitor switch signals are invalid, shifting to1st and 2nd gear is forbidden. (Limp-home C)

The TCU communicates with other vehicle electronic control modules by the controller area network

(CAN). If a major fault is developed, the transaxle may not accomplish the intelligent shift control. The

TCU controls the transaxle with preset values.

The TCU also provides for transaxle diagnostics, which meet the requirements of OBD II regulation,

monitoring all components which may effect vehicle emissions.

Towing the automatic transaxle equipped vehicle

▶

Flat-bed equipment is the best method of moving a disabled vehicle to avoid any damages.

For AWD vehicle: The vehicle must be towed with a wheel lift and dollies or flatbed equipment with

all the wheels off the ground.

For 2WD vehicles: It is acceptable to tow the vehicle with the rear wheels on the ground without

dollies and the front wheels off the ground. When being towed by a commercial towtruck and

wheel dollies are not available, the front of the vehicle should be lifted, not the rear.

5. TRANSAXLE ELECTRONIC CONTROL SYSTEM

1) General Information

The transmission control unit (TCU) and its input/output network control the following transmission

operations:

Shift timing

Line pressure

Clutch pressure (shift feel)

Torque converter clutch

-

-

-

-

also uses these signals when determining transaxle operating strategy. Using all of these input signals,

the TCU can determine when the time and conditions are right for a shift, or when to apply or release the

torque converter clutch. It will also determine the pressure needed to optimise shift feel.

2) TCU (Transmission Control Unit)

The transaxle control unit (TCU) is mounted

under the driver's seat and controls the operation

of the transaxle.

Internal sensors and signals received across the

CAN bus in analogue and digital forms such as:

Transaxle input speed

Transaxle output speed

Accelerator pedal position

Gear selector position

Engine torque

Engine speed

Transaxle fluid temperature

Brake pedal status

Engine oil temperature

Engine coolant temperature

Ambient air temperature

Barometric pressure

The TCU monitors all TCU inputs and outputs to confirm correct system operation. If a fault occurs the

TCU is able to perform default action and inform the driver of the problem through the instrument cluster

warning lights. Detailed information is available via trouble codes which can be read with the service tool.
