1. GUIDELINES FOR SERVICE WORKS
1) For Safety
To perform the service works easily ans safely, the service technicians must keep the proper working
procedures and rules.
This manual provides the useful instructions to the service technicians so that they can perform the
servive works with standard working process, skills, tips in time.
Please read this manual and follow the instructions carefully.
Signal words such as “WARNING”, “CAUTION” and “NOTE” have special meanings.
indicates information to assist maintenance and instructions.
However, above references and cautions cannot be inclusive measures, so should have habits of
paying attentions and cautions based on common senses.
indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate
injury or property damage.
indicates a potentially hazardous situation which, if not avoided, could result in death or serious
injury.

4) Basic Inspection
(1) Horn operation
Listen for the horn sound when pressing the horn pad on the steering wheel. -
(2) Brake operation
Check if there is any abnormal noise, unusually long braking distance, or uneven braking force. If the
brake warning lamp does not go out even after starting the engien or are flashing during driving,
have the brake system checked immediately.
Check the brake pipes and hoses for connection, oil leak, crack or interference after changing the
position of tires. When replacing the tires, check the brake disc for surface condition and wear.
Check the parking brake cable and brake operation. Shorten the checking interval if the parking
brake is used frequently. -
-
-
(3) Exhaust system
Be aware to any changes in sound or smell from the exhaust system. These may be caused by leak or
overheat. Have the exhaust system checked and repaired immediately.
Inspect the exhaust system including catalytic converter. Inspect all the components and body frame
near the exhaust system. -
-
(4) Tires
Unusual vibration of the steering wheel and seats or pulling to one side on the straight and level roads
may indicates the uneven tire inflation pressure or poor wheel balance. -
(5) Steering and suspension system
Inspect the front and rear suspension and the steering system for damage, looseness or missing
parts, signs of wear or lack of lubrication. Inspect the power steering line and the hoses for
connection, leak, crack and chafing. Inspect the drive axle boot and seals for damage, tear or leak.
Replace or repair the system if necessary. -
(6) Engine oil
Check the oil level when the engine is still warm and add the specified engine oil if necessary. -
(7) Coolant
Check the coolant level in the coolant reservoir, coolant conditions (contamination, foreign material),
and hoses for damage and leak. Replace or add the Ssangyong genuine coolant, if needed. -
(8) Engine drive belt
Check all drive belts on the engine for wear, crack and looseness. Retighten or replace the belt, if
needed. -

This information is used by the TCU to decide which shift pattern to select and for shift energy
management. Electro-hydraulic solenoid valves and variable bleed solenoids control the transaxle gear
changes.
Six variable bleed solenoids and four on/off solenoids are used to direct transaxle fluid flow to control the
fluid pressure within the three clutches and two bands. Separate pressure regulators are used
exclusively for torque converter clutch control and main transaxle line 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.

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 -

4. WARNING LAMPS
1) ABS Warning Lamp
ABS warning lamp module indicates the self diagnosis and malfunction.
ABS warning lamp ON:
When turning the ignition switch to ON position, ABS warning lamp comes on for 3 seconds for self-
diagnosis and goes off if the system is OK (initialization mode).
When the system is defective, the warning lamp comes on.
When the self-diagnosis is performing, the warning lamp comes on.
When the HECU connector is disconnected, the warning lamp comes on.
ABS is not available during lamp ON. In this condition, Only normal brake system without ABS function
is available.
When the communication between warning lamp CAN module in meter cluster, the warning lamp
comes on. 1.
