Regeneration of particle filter

This function cleans the particle filter from soot particles by burning them off using an increase in the exhaust temperature. In certain driving conditions, the particle filter can not be cleaned automatically, e.g., in continuous city driving. Then this function is used to force a regeneration.
Note:
When the engine warning lamp illuminates with the DPF warning mark shown in the multi information display, the forcible regeneration of the DPF must be carried out.
This is a two-person job and the diagnostic tool must be connected during the time that the regeneration is run.
Use the diagnostic tool to check whether the forcible regeneration of the DPF is carried out or not. Check that the data list "Diesel particulate filter regeneration operation" has the status on. If the forcible regeneration of the DPF is not carried out, slightly increase the engine speed. Stopping the vehicle stops the forcible regeneration of the DPF. If driving again within 100 seconds, the forcible regeneration of the DPF is restarted.
If the DPF warning mark is not extinguished even though running the engine more than 60 minutes, carry out the troubleshooting.
Test conditions:
Procedure:
  1. Start the function and follow the instructions in the program.
  2. Check that the DPF warning mark is changed from red to the yellow.
  3. Drive the vehicle for approximately 20 - 45 minutes.
  4. The regeneration is complete when the DPF warning mark is changed from yellow to red. Check that the warning mark in the multi information display goes out after approx. 4 seconds.
  5. Turn off the engine and confirm that the DPF warning mark does not show by restarting the engine.
  6. Erase any fault codes.
