2) ECU Control
(1) Function
a. ECU Function
ECU receives and analyzes signals from various sensors and then modifies those signals into
permissible voltage levels and analyzes to control respective actuators.
ECU microprocessor calculates injection period and injection timing proper for engine piston speed
and crankshaft angle based on input data and stored specific map to control the engine power and
emission gas.
Output signal of the ECU microprocessor drives pressure control valve to control the rail pressure and
activates injector solenoid valve to control the fuel injection period and injection timing; so controls
various actuators in response to engine changes. Auxiliary function of ECU has adopted to reduce
emission gas, improve fuel economy and enhance safety, comforts and conveniences. For example,
there are EGR, booster pressure control, autocruise (export only) and immobilizer and adopted CAN
communication to exchange data among electrical systems (automatic T/M and brake system) in the
vehicle fluently. And Scanner can be used to diagnose vehicle status and defectives.
Operating temperature range of ECU is normally -40 to +85°C and protected from factors like
oil, water and electromagnetism and there should be no mechanical shocks.
To control the fuel volume precisely under repeated injections, high current should be applied instantly
so there is injector drive circuit in the ECU to generate necessary current during injector drive stages.
Current control circuit divides current applying time (injection time) into full-in-current-phase and hold-
current-phase and then the injectors should work very correctly under every working condition.
b. Control Function
Controls by operating stages
To make optimum combustion under every operating stage, ECU should calculate proper injection
volume in each stage by considering various factors.
Starting injection volume control
During initial starting, injecting fuel volume will be calculated by function of temperature and engine
cranking speed. Starting injection continues from when the ignition switch is turned to ignition
position to till the engine reaches to allowable minimum speed.
Driving mode control
If the vehicle runs normally, fuel injection volume will be calculated by accelerator pedal travel and
engine rpm and the drive map will be used to match the drivers inputs with optimum engine power. -

A. Overview of cooling fan and A/C compressor
The cooling system maintains the engine temperature at an efficient level during all engine operating
conditions. The water pump draws the coolant from the radiator. The coolant then circulates through
water jackets in the engine block, the intake manifold, and the cylinder head. When the coolant
reaches the operating temperature of the thermostat, the thermostat opens. The coolant then goes
back to the radiator where it cools. The heat from automatic transmission is also cooled down through
the radiator by circulating the oil through the oil pump. ECU controls the electric cooling fans with three
cooling fan relays to improve the engine torque and air conditioning performance.
For detailed information, refer to Chapter "Air Conditioning System".

E. Cautions
Use only specified Engine Oil (approved by MB Sheet 229.51) for CDPF. -
Use only specified engine oil (Low Ash Oil) ▶
The vehicle equipped with CDPF should use specific engine oil to improve the engine
performance and fuel economy, and ensure the service life of CDPF. -
Issue with normal engine oil ▶
Sulfur, one of the contents of engine oil is burned and generates soot that is not regenerated by
the DPF. This remains on the filter as ashes and keeps accumulating. Eventually, this ashes will
block the filter. -
Benefit for specified engine oil ▶
Minimized the sulfur content of engine oil which reduces the service life.
Improved fuel economy and emission level of CO2 with high performance and low viscosity.
Increased service life of engine oil with high resistance to temperature. -
-
-
Problems when using unspecified engine oil ▶
The service life of filter may be reduced by 30% or more by the ashes accumulated on the filter.
The fuel economy may be reduced because of engine rolling resistance, frequent regeneration of
DPF. -
-
These problems are also caused by oil with high sulfur content, such as tax exemption oil and
heating oil, etc. *

Shock Absorber Assembly
Stabilizer Bar Assembly
The stabilizer bar is intended to force each side of the vehicle to lower, or rise, to similar heights, to
reduce the sideways tilting (roll) of the vehicle on curves, sharp corners, or large bumps. The basic
function is to force the opposite wheel's shock absorber, spring or suspension rod to lower, or rise, to a
similar level as the other wheel. In a fast turn, a vehicle tends to drop closer onto the outer wheels, and
the sway bar will soon force the opposite wheel to also get closer to the vehicle. As a result, the vehicle
tends to "hug" the road, closer in a fast turn, where all wheels are closer to the body. After the fast turn,
then the downward pressure is reduced, and the paired wheels can return to their normal height against
the vehicle, kept at similar levels by the connecting stabilizer bar.

Coil spring -
The shock absorber assembly reduces the effect of traveling over
rough ground, leading to improved ride quality and increases in
comfort. While shock absorber serves the purpose of limiting
excessive suspension movement, their intended sole purpose is to
dampen spring oscillations. The shock absorber in this vehicle uses
the gas to absorb excess energy from the spring.
Shock absorber -
Keep the clearance to drive shaft.
To prevent the transverse force to shock absorber, the upper
center line and the lower center line of shock absorber are
placed on same line. 1.

Oil Level Check ▶
Check the fluid level on a level ground with the
engine turned off. The fluid level should be
between the MIN and MAX marks on the
reservoir cap gauge.
Place the vehicle on a level ground and start
the engine and let it run at idle speed.
Turn the steering wheel several times so that
the oil temperature reaches to normal
operating level (75~85˚C).
Place the steering wheel at straight ahead
direction.
Check the oil level in the power steering oil
reservoir. Adjust the oil level between MAX
and MIN. A.

Oil Change ▶
If the difference between two measurements
is below 5 mm and the level is between MAX
and MIN level, it's normal. If it is over 5 mm,
bleed air from the system.
Open the power fluid reservoir cap and drain
the fluid completely with oil suction device.
To make it easy, turn the steering wheel to
its both ends several times.
Fill up the specified fluid into fluid reservoir
and bleed air from the steering system. A.
