4) Throttle Body for Different Engines
The throttle body is not installed in the D27DT engine (general), but is installed in the following
engines:
1) D27DT (EU IV) engine
2) D27DTP (POWER UP) engine
3) D27DTP (POWER UP) engine + CDPF
Both engines are equipeed with the throttle body, but its appearance and the related control
system are differ.

5) Operating Procedures of CDPF
The most efficient and practical technology for now is adopted to the diesel particulate filter
(DPF).
This system collects the soot from the diesel engine to the filter and burns the soot so that ove
r
than 95% of soot can be removed from the exhaust gas. However, the durability and the cost o
f
additional system remain as problems.
Firstly, the exhaust gas is passed through the DOC and its temperature is increased as it is
oxidized. The ECU detects the temperature change with two temperature sensors. The CO, HC
and partial particulate material are removed from the exhaust gas (this procedures are the
sames as the ones for the conventional DOC and no sensor is required).
After the exhaust gas is passed through the DOC and oxidized, most of the harmful material is
removed from the exhaust gas. However, to meet the environmental regulations in the future,
the soot is filtered and burnt again in DPF to decrease the particulate material further.
The filtered soot is burned whenever the vehicle is driven for 600 ~ 1200 km. The driving
distance can be differed depending on the vehicle’s driving conditions. The soot is
burnt for 15 ~ 20 minutes.

6) CDPF Over Load (Notice of Beginning CPF Regeneration Mode
- P1430)
The CDPF system enters the regeneration mode when the mileage is around 600 ~ 1,200
km, depending on the driving condition and driving habits. At this moment, the ECU
performs the CDPF regeneration process; however, the driver may not notice anything
because there is no engine warning or other signals indicating such process.
The control logic in the regeneration process is to increase the exhaust gas temperature by
increasing the fuel injection during post injection process and controlling the intake ai
r
amount(throttle body), and no significant change can be noticed in the vehicle condition.
The engine CHECK lamp flashes but there is no decrease in engine torque.
The engine CHECK lamp flashes to inform the driver when there is an over load due to soot
accumulation because the regeneration temperature cannot be reached due to low speed,
even though CDPF regeneration is in process.
The CDPF regeneration process must be completed by driving for 15-20 minutes at a speed
higher than 80 km/h to solve this problem.
The engine CHECK lamp flashes when CDPF is over loaded; therefore, 4) above must be
performed in this case. 1.

7) CDPF's Excessive Soot Accumulation (P0432)
When the vehicle is driven at a low speed (5-10 km/h) for a long time or long distance, the
soot over accumulates inside the CDPF and the combustion temperature cannot be reached
even by performing the soot combustion process. In this case, this DTC is generated.
This is more serious situation than the CDPF over load condition. Therefore, the engine
power is decreased to protect the system and the engine CHECK lamp is turned on.
Blow the soot between the engine and the exhaust system several times and clear the DTC
to solve this problem. If the same DTC is generated again, check the system according to
the DTC description related to the differential pressure sensor.
* This DTC is actually generated mostly due to the related system malfunction, such as
differential pressure sensor malfunction. 1.

1. COMPARISON IN COOLING SYSTEM FOR EACH ENGINE
For the D27DTP (POWER UP) 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. For the
D27DT engine, the cooling system uses the fan clutch.

The fuse box is underneath the dash board on the driver's side. You can find the function,
location and capacity for fuses from the back plate of the fuse box cover. If any electrical device
doesn't operate, check for an open fuse. If any fuse is blown, replace it with a new fuse.
If a new fuse also opens, have the electrical system checked and repaired by Ssangyong
Dealer or Ssangyong Authorized Service Operation.

STICS
If the washer operating signal is inputted while the wipers are operating in intermittent or
AUTO mode, the system stores the previous intermittent interval and operates the washe
r
coupled wiper. After then, the wiper operation returns back to intermittent or AUTO mode
with the stored operating interval. 3.
