Nissan Juke Service and Repair Manual : DPF (diesel particulate filter) data clear

Description

Perform ???DIESEL PARTICULATE FILTER DATA CLEAR??? in ???WORK SUPPORT??? mode with CONSULT-III when oxidation catalyst with diesel particulate filter is replaced as new one. Based on the signal from sensors ECM estimates the amount of particulate matter in diesel particulate filter and stores the value in EEPROM as diesel particulate filter data. When oxidation catalyst with diesel particulate filter is replaced as new one, there is a difference between diesel particulate filter data stored in ECM and the actual amount of particulate matter in diesel particulate filter, because no particulate matter is trapped in new diesel particulate filter. In this case, ECM cannot perform regeneration control correctly. So perform ???DIESEL PARTICULATE FILTER DATA CLEAR??? in ???WORK SUPPORT??? mode with CONSULT-III to clear diesel particulate filter data stored in ECM.

CAUTION:
Never perform ???DIESEL PARTICULATE FILTER DATA CLEAR??? in ???WORK SUPPORT??? mode with CONSULT- III when oxidation catalyst with diesel particulate filter is not replaced as new one. Diesel particulate filter may be damaged because regeneration is not performed at appropriate timing.

Work Procedure

1.START

1. Turn ignition switch ON.

2. Select ???DIESEL PARTICULATE FILTER DATA CLEAR??? in ???WORK SUPPORT??? mode with CONSULT-III.

3. Touch ???CLEAR??? and wait a few seconds.

4. Make sure that ???CMPLT??? is displayed on CONSULT-III screen.
