DIESEL PARTICULATE FILTER REGENERATION [MZ-CD 1.6 (Y6)]

id0116c3805100

Warning

•  High temperature exhaust gas is emitted during diesel particulate filter manual regeneration. People near the vehicle could be seriously burned, or flammable objects could catch fire. Always perform diesel particulate filter regeneration away from people and flammable objects.

•  If large amounts of exhaust gas are inhaled, it may cause carbon monoxide poisoning. Always perform diesel particulate filter manual regeneration in a well-ventilated place. (Avoid performing diesel particulate filter manual regeneration indoors using an exhaust air duct. Perform it in the open air.)

Caution

•  If the general vehicle condition or state of repair and servicing is not acceptable (engine oil level, drive belt, engine coolant level), diesel particulate filter manual regeneration cannot be performed correctly. Make sure the general vehicle condition or state of repair and servicing is acceptable, before performing the diesel particulate filter manual regeneration.

•  If there are obstructions such as a wall around the tailpipe during diesel particulate filter manual regeneration, it will obstruct the exhaust gas passage (airflow), and the diesel particulate filter manual regeneration may not be performed correctly due to the increase in exhaust gas temperature. Always perform diesel particulate filter regeneration with no obstructions around tailpipe.

Note

•  If the diesel particulate filter manual regeneration is canceled by depressing the brake pedal:

1.  Stop the vehicle.

2.  Apply the parking brake.

3.  Remove the under cover.

4.  Connect the M-MDS to the DLC-2.

5.  Warm up the engine to above 65 °C {149 °F}, or perform the M-MDS warm up procedure.

6.  After the vehicle is identified, select the following items from the initial screen of the M-MDS.

•  When using the IDS (notebook PC)

1.  Select “Powertrain”.

2.  Select “Service Function”.

3.  Select “DPF Component Parameter Commands”.

•  When using the PDS (pocket PC)

1.  Select “All Tests and Calibrations”.

2.  Select “DPF Component Parameter Commands”.

7.  Then, select “Static regeneration” and perform procedures according to the directions on the M-MDS screen.

Note

•  Even when diesel particulate filter regeneration is finished and the MIL turns off, DTCs (P242F, P2458) are still recorded in the PCM as a past malfunction. Erase all DTCs using the M-MDS after diesel particulate filter regeneration is finished. (See AFTER REPAIR PROCEDURE [MZ-CD 1.6 (Y6)].)

8.  Retrieve DTC’s using the M-MDS, then verify that DTCs are present.

•  If a DTC is present, perform the applicable DTC inspection. (See DTC TABLE [MZ-CD 1.6 (Y6)].)
