SERVICE REGENERATION

Description

INFOID:0000000010289696

Certain types of driving conditions (e.g. urban driving) may load to heavy loads in DPF (Diesel Particulate Fil-
ter). This soot mass may adversely affect the driving. This function can perform DPF regeneration under vehi-
cle stop condition.
Service regeneration is performed with CONSULT to reduce particulate matter in DPF (Diesel Particulate Fil-
ter). Service regeneration should be performed in the following cases.
• ECM enters fail-safe mode because the amount of particulate matter in DPF reaches the specified level.

NOTE:
When ECM enters fail-safe mode because the amount of particulate matter in DPF reaches the specified
level, check whether or not DTC P2002 is stored in ECM. In the case of DTC stored, perform the Diagnostic
Procedure for the DTC.

• ECM is replaced.

NOTE:
• Based on the signal from sensors ECM measures the amount of particulate matter in DPF and stores the

value in EEPROM (Electrically Erasable Programmable Read Only Memory). When ECM is replaced as
new one, there is a difference between the actual amount of particulate matter and the value stored in new
ECM, because the value stored in new ECM is initialized one. In the case above, ECM can not perform
regeneration control correctly. So, perform service regeneration to make the amount of particulate matter
in DPF zero.

• The necessary operation is different depending on the operation result of ECM data save or write. Always

perform the operation according to procedures. Refer to 

ECK-131, "Work Procedure"

.

• Component inspection for DPF is performed.

CAUTION:

Oil change is required, depending on service regeneration procedure. Because fuel mixes with
engine oil during service regeneration. The mixture does not occur during the regeneration which is
automatically performed under normal operation.
