The engine ECUs are various according to the engine model (D20DT engine, D20DT (EURO4)
engine). For the D20DT (EURO4) engine, one connector is added to the engine ECU (2
connectors total) to control the additional sensor, actuator and exhaust gas control function.
For the D20DT (EURO4) engine, the connector pin is added and DTC is changed as the
following components are added. the functions of engine ECU pin for D20DT (EURO4) engine
and D20DT engine are not same. For more details, refer to the respective section.
It is electrically controlled by the ECU for precise control. Old version was controlled by the
vacuum modulator.
It is electrically controlled by ECU as E-EGR valve.
The glow control relay (K-line communication with engine ECU) is deleted. The unit
communicates via CAN communication with engine ECU. Also, the number of pins is
increased as glow plug's performance has been improved (1000 C increase in approx. 2
seconds).

When you are inspecting or replacing exhaust system components, make sure there is
adequate clearance from all points on the underbody to avoid possible overheating of the
floor panel and possible damage to the passenger compartment insulation and trim
materials.
Check the complete exhaust system and the nearby body areas and trunk lid for broken,
damaged, missing or mispositioned parts, open seams, holes, loose connections, or othe
r
deterioration which could permit exhaust fumes to seep into the trunk may be an indication
of a problem in one of these areas. Any defects should be corrected immediately. -
Aside from the exhaust manifold connection, the exhaust system uses a flange and seal joint
design rather than a slip joint coupling design with clamp and U-bolts.
If hole, open seams, or any deterioration is discovered upon inspection of the front muffler and
pipe assembly, the complete assembly should be replace, the complete assembly should be
replaced.
The same procedure is applicable to the rear muffler assembly. Heat shields for the front and
rear muffler assembly and catalytic converter protect the vehicle and the environment from the
high temperatures that the exhaust system develops.
When jacking or lifting the vehicle from the body side rails, be certain that the lift pads do
not contact the catalytic converter, as this could damage the catalytic converter. -
Use of anything other than unleaded fuel will damage the catalyst in the catalytic converter. -
The catalytic converter are emission-control devices added to the exhaust system to
reduce pollutants from the exhaust pipes.
The oxidation catalyst is coated with a catalytic material containing platinum and
palladium, which reduces levels of hydrocarbon (HC) and carbon monoxide (CO) from
the exhaust gas. The three-way catalyst has coatings which contain platinum and
rhodium, which additionally lower the levels of oxides of nitrogen (NOx).
