Regeneration of the particulate filter
The particulate filter is regenerated, i.e. cleaned, automatically. If a certain amount
of soot is accumulated, the engine enters a periodic and automatic program to reduce
the amount of soot. The engine can be used without any impact on operation.
However, if the particulate filter becomes full, it must be regenerated manually. The
engine cannot be used for approximately 45 minutes while manual regeneration is
carried out. To indicate that the particulate filter is full and needs to be regenerated
manually, the CAN message DPFC1 is used. See 03:05 CAN interface.
In order to indicate that the particulate filter needs to be regenerated manually, Scania
recommends that the symbol for particulate filter regeneration according to
ISO 7000 - 2433 is used.
Other CAN messages related to the particulate filter are:
• DLN2: Shows current status for automatic and manual regeneration.
• DLN8: Shows remaining time for manual regeneration.
• AT1S1: Shows the level of soot and ash as a percentage.
• ADC: Acknowledgement for safe start of manual particulate filter regeneration.
• CM1: Starting and stopping manual particulate filter regeneration.
