d. Operation process
When the differential pressure sensor detects the pressure difference between the front and the rear
side of CDPF, the sensor sends signal indicating the soot is accumulated and the post injection is
performed to raise the temperature of exhaust gas. The amount of fuel injected is determined according
to the temperature of exhaust gas detected by the rear temperature sensor. If the temperature is below
low load range, the amount of post injection and the amount of intake air are controlled. It is to raise the
temperature by increasing the amount of fuel while decreasing the amount of intake air.

e. Cautions
Use only specified Engine Oil (approved by MB Sheet 229.51) for CDPF. -
1. 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. -
2. 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. -
3. 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. -
-
-
4. 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. *

3) Input/Output for CAN communication
(1) Configuration of CAN (P-CAN/B-CAN)
CAN Topology communicate with system units. There are two types (P-CAN and B-CAN) of
communication according to the communication speed. Instrument cluster, BCM and diagnostic
connector use both types of communication. And, ECU, ABS & ESP, TCU, GCU, E-coupling and EPS
unit use P-CAN communication because it is faster than B-CAN. The terminal resistances are installed in
ECU and BCM.
