2) Fuel Injection During CDPF Regeneration
3) Warning Lamp Related To CDPF
CDPF regeneration process (warning lamp NOT illuminated)
The CDPF system enters the regeneration mode when the
driving distance becomes approx. 600 to 1,200 km (may
differ by the driving condition and driving style). Then, the
engine ECU performs the CDPF regeneration operation.
However, the driver is not in-formed with this operation by an
y
engine warning lamp or vehicle signal, so he/she may not
detect this operation. The control logic at the post-injection
dur-ing the regeneration process is to increase the fuel
injection volume and control the intake air volume (by the
throttle body) in order to increase the tem-perature of the
exhaust gas. The driver may not feel any particular difference
from the vehicle.

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.

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

3. CAUTIONS FOR DI ENGINE
1) Cautions for DI Engine
This chapter describes the cautions for DI engine equipped vehicle. This includes the water separation
from engine, warning lights, symptoms when engine malfunctioning, causes and actions.
DI Engine 1.
Comparatively conventional diesel engines, DI engine controls the fuel injection and timing electrically,
delivers high power and reduces less emission..
System Safety Mode 2.
When a severe failure has been occurred in a vehicle, the system safety mode is activated to protect the
system. It reduces the driving force, restricts the engine speed (rpm) and stops engine operation. Refer
to "Diagnosis" section in this manual.
Engine CHECK Warning Lamp 3.
The Engine CHECK warning lamp on the instrument cluster comes on when the fuel or
major electronic systems of the engine are not working properly. As a result, the
Water Separator Warning Lamp 4.
When the water level inside water separator in fuel filter exceeds a certain level (approx.
45 cc), this warning light comes on and buzzer sounds.
Also, the driving force of the vehicle decreases (torque reduction). If these conditions
occur, immediately drain the water from fuel filter.

(2) Di engine and its expected problems and remedies can be caused by
water in fuel
System supplement against paraffin separation
In case of Diesel fuel, paraffin, one of the elements, can be separated from fuel during winter and then
can stick on the fuel filter blocking fuel flow and causing difficult starting finally. Oil companies supply
summer fuel and winter fuel by differentiating mixing ratio of kerosene and other elements by region and
season. However, above phenomenon can be happened if stations have poor facilities or sell improper
fuel for the season. In case of DI engine, purity of fuel is very important factor to keep internal
preciseness of HP pump and injector.
Accordingly, more dense mesh than conventional fuel filter is used. To prevent fuel filter internal clogging
due to paraffin separation, SYMC is using fuel line that high pressure and temperature fuel injected by
injector returns through fuel filter to have an effect of built-in heater (see fuel system).
System supplement and remedy against water in fuel
As mentioned above, some gas stations supply fuel with excessive than specified water. In the
conventional IDI engine, excessive water in the fuel only causes dropping engine power or engine
hunting. However, fuel system in the DI engine consists of precise components so water in the fuel can
cause malfunctions of HP pump due to poor lubrication of pump caused by poor coating film during high
speed pumping and bacterization (under long period parking). To prevent problems can be caused by
excessive water in fuel, water separator is installed inside of fuel filter. When fuel is passing filter, water
that has relatively bigger specific gravity is accumulated on the bottom of the filter.
Water drain from water separator
If water in the separator on the fuel filter exceeds a certain level, it will be supplied to HP pump with fuel,
so the engine ECU turns on warning lamp on the meter cluster and buzzer if water level is higher than a
certain level.
Due to engine layout, a customer cannot easily drain water from fuel filter directly, so if a customer
checks in to change engine oil, be sure to perform water drain from fuel filter.
Water
separator
To separate the water from the fuel filter,
remove the fuel filter assembly first.

1. SYSTEM DESCRIPTION
1) Overview
The lubrication system supplies oil to each lubrication section to prevent friction and wear and to remove
heat from the friction part. As the engine runs, frictional heat is generated on each lubrication section. If
this condition persists, the bearing can be burned and stuck.
In other words, it creates an oil film on each sliding surface to convert solid friction to liquid friction in order
to minimize wear and prevent temperature increasing on the friction part.
For the D20DTF engine with no oil pressure switch, the engine ECU receives the low engine oil level
signal from the oil level sensor and communicates with the instrument cluster through the CAN
communication to turn on the warning lamp.
