Overload of CDPF (warning lamp blinking)
Excessive overload of CDPF (warning lamp illuminated)
If the CDPF cannot reach the regeneration tem-
perature due to low speed driving or other reason during
the regeneration process, the soot is con-tinuously
accumulated in the CDPF. When this condition continues
and the CDPF is overloaded with soot, the engine
warning lamp blinks to in-form this situation to the driver.
In order to solve this problem, drive the vehicle at a speed
of approx. 80 km/h for 15 to 20 minutes to perform the
CDPF regeneration process.
If the engine warning lamp on the instrument clus-te
r
blinks, the CDPF is overloaded. In this case, perform the
step 2. 1.

3.
If the vehicle is driven at a speed of 5 to 10 km/h for an
extended period of time, the soot accumu-lated in the
CDPF cannot be burnt as the CDPF cannot reach the
regeneration temperature. Then, an excessive amount o
f
soot can be accumulated in the CDPF.
This case is much worse than the simple over-load of the
CDPF. To inform this to the driver, the engine warning
lamp comes on and the engine power is decreased to
protect the system.
To solve this problem, blow soot between the en-gine and
exhaust system several times and erase the related DTC.
Then, check if the same DTC is regenerated again. If so,
check the DTC related to the differential pressure sensor. 1.

3.
Actually, the DTC for the CDPF is generated more often by the component related to the CDPF system,
such as the differential pressure sensor, than by excessive soot in the CDPF. Blinking

PCV Oil Separator
Oil Pan & Baffle Plate (Integrated type) Oil Strainer
The first separation will happen when blow-by gas
passes through baffle plates in cylinder head cover.
Then oil and gas will be separated due to cyclone
effect after entering the oil separator inlet port.
Separated oil returns to oil pan via oil drain port and
the gas will be burnt again after entering the
combustion chamber through air duct hose via
PCV valve that opens/closes due to pressure
differences between the intake side and crankcase.

For the D20DT (EURO4) engine, the cooling system is equipped with E-EGR cooler and the water pump
which its capacity is improved according to the additional coolant line in the cylinder block.
