Particle filter regeneration
This procedure is for forced regeneration of the particle filter (DPF) using a diagnostic system scanner (GDS), if the particle filter has not been regenerated while driving. For example, if the vehicle was driven intermittently at low speed, for short distances, or with intermittent idling, the particulate filter regeneration procedure was not performed because the conditions for regeneration mode were not met.
Conditions for forced regeneration
Engine coolant temperature: about 70°C.
The engine is running at idle.
Gear lever position «R» (parking) (for automatic transmission) or «neutral» (for manual transmission).
Normal battery voltage.
Full electrical load (air conditioning included (if installed), fan at maximum speed, headlights, windshield wipers, other lighting devices, etc.).
The hood is open.
The amount of soot is less than 25 g. (indication of the electronic engine control unit).
Note: The air conditioner consumes a lot of electricity. For faster regeneration, turn it on (if it is installed).
1. Turn off the ignition.
2. Connect the diagnostic system scanner (GDS) to the diagnostic socket (DLC).
3. Start the engine at idle and in the shift lever position «R» (for automatic transmission) or «neutral» (for manual transmission).
4. Apply the maximum electrical load to the car (the air conditioner is on, the fan is on at maximum speed, the headlights are on, the windshield wipers are on, the rest of the lights are on, etc.).
5. Select «Vehicle, Model year, Engine, System» (car, model year, engine, system).
6. Select «Vehicle S/W Management» (Vehicle software control).
7. Select «DPF Service Regeneration» (Service regeneration of the particulate filter (DPF)).
8. Follow the procedure as instructed on the screen.
Note: If the condition of the particle filter (DPF) does not meet the required conditions, the regeneration will end with an unsatisfactory result.
Withdrawal
Attention.
- Before removing the particle filter (DPF) assembly must be checked for damage.
- Remove the exhaust pipe from the particulate filter side. Check the rear of the particle filter for damage or discoloration (white color).
- Check for soot at the rear of the particle filter. If soot is visible, the particle filter pressure change sensor (DPS) may be faulty.
1. Turn the ignition key to the OFF position and disconnect the negative (-) battery cable.
2. Disconnect the connector (A) oxygen sensor, then remove the heat shield (IN).
3. Disconnect the connector (A) exhaust gas temperature sensor and connector (IN) particulate filter pressure sensor (DPF).
4. Disconnect the hoses (A) particulate filter pressure change sensor (DPF) assembled.
Attention. Be careful not to mix up the rear and front hoses when disconnecting and connecting.
5. Lift the car and turn away a nut of fastening of the forward muffler.
6. Remove supports (A, B) particulate filter (DPF) assembled.
Note:
Torque:
- Particle filter support bolt: 44.1 ~ 54.0 Nm.
- Front muffler mounting nut: 39.2 ~ 58.8 Nm.
7. Loosen the fixing nuts (A) and loosen the fixing screws (IN) from the turbocharger, then remove the particle filter (DPF) assembled.
Note: Tightening torque:
- Particle filter mounting bolt: 44.1 ~ 54.0 Nm.
- Diesel particulate filter nut: 49.1 ~ 68.7 Nm.
Installation
Installation is carried out in the reverse order of removal.
Attention.
- Take care not to allow foreign material to enter the pipes and the particle filter itself.
- If foreign matter enters the particle filter or its tubes, the particle filter may be damaged, or permanent/excessive contamination may occur.
- Tighten the component mounting bolts to the correct torque.
Replacement
Attention. After replacing the particulate filter (DPF) assembled, follow the procedure «Component Change Routine» (Component replacement program). Otherwise, a malfunction related to engine performance or exhaust control may occur and remain until the data on the new component is registered in the engine control unit.
1. Turn off the ignition.
2. Connect the diagnostic system scanner (GDS) to the diagnostic socket (DLC).
3. Turn on the ignition.
4. Select «Vehicle, Model year, Engine, System» (car, model year, engine, system).
5. Select «Vehicle S/W Management» (Vehicle software control).
6. Select «Component Change Routine» (Component replacement program).
7. Select «DPF Change» (Replacing the particle filter (DPF)).
8. Follow the procedure as instructed on the screen.
