FORCIBLE DPF REGENERATION


warning When the forcible DPF regeneration is carried out, confirm that no people or no combustible material is within its vicinity. If people or combustible material is around the muffler, serious injury or damage such as heat injury or fires may occur because high temperature exhaust gases are put out.
warning Perform the forcible DPF regeneration in a well-ventilated and flat place when the vehicle is stopped (If perform the forcible DPF regeneration indoors, surely carry out enforced ventilation).
warning If the engine warning lamp is lit, the DPF system might be abnormal. Carry out the inspection chart for diagnosis code, and then perform the forcible DPF regeneration (Refer to , GROUP 13B - Troubleshooting - Inspection Chart For Diagnosis code).
1.Set the vehicle to the pre-inspection condition.
caution Connection and disconnection of M.U.T.-III should be always performed with the ignition switch turned to the "LOCK" (OFF) position.


2.Connect the M.U.T.-III to the diagnosis connector.
3.Start the engine and let it run at idle.
4.From "FUNCTION MENU" on M.U.T.-III, select "SPECIAL FUNCTION".
5.From "SPECIAL FUNCTION", select "DPF REGENERATION".
caution If the forcible regeneration of the DPF is carried out while the accumulated amount of the PM in the DPF exceeds the limit, the forcible regeneration might not be correctly completed. This could be caused by the detection in the DPF system malfunction. Carry out the check procedure for the diagnosis code and solve the malfunction. (Refer to , GROUP 13B - Troubleshooting - Inspection Chart For Diagnosis Code)
6.Perform Item No. 33, DPF Regeneration.
note Carrying out the forcible DPF regeneration increases the engine speed 1,500 - 2,000 r/min (the temperature increases within the DPF and is maintained at approximately 600°C).
note When performed for about 25 minutes, the forcible DPF regeneration automatically stops. Depressing the accelerator pedal during the regeneration, however, can cancel the forcible DPF regeneration.
note If the DPF regeneration is carried out while the DPF lamp is illuminated or blinked due to the accumulated PM, the DPF lamp is turned off as soon as the forcible regeneration is correctly completed.
7.Turn the ignition switch to the "LOCK" (OFF) position and then remove the M.U.T.-III.
