Diesel Engines
NOTE: Do NOT perform automatic regeneration when the soot accumulation rate in the DPF
is 100 % or more, since this may cause damage to the filter or the engine.
•
If the soot accumulation rate in the DPF reaches 140 % or more, the MIL also illuminates
and DTC P242F is stored in the PCM. In addition, the PCM further reduces the fuel
injection amount and hence the soot emission of the engine, resulting in a lower soot
amount accumulated in the filter. Here, a manual regeneration of the DPF must also be
performed.
•
If the soot accumulation rate in the DPF reaches 200 %, the filter cannot be regenerated
anymore and must therefore be replaced.
•
The different conditions of the soot accumulation in the DPF are shown in the following
