DIESEL PARTICULATE FILTER DATA CLEAR

DIESEL PARTICULATE FILTER DATA CLEAR

Description

INFOID:0000000010289698

Perform “DPF DATA CLEAR” in “WORK SUPPORT” mode with CONSULT when oxidation catalyst with diesel
particulate filter is replaced with a 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 with a new one, there is a difference between
diesel particulate filter data stored in ECM and the actual amount of particulate matter in diesel particulate fil-
ter, because no particulate matter is trapped in new diesel particulate filter. In this case, ECM cannot perform
regeneration control correctly. So perform “AFTER DPF REPLACEMENT” in “WORK SUPPORT” mode of
“ENGINE” using CONSULT to clear diesel particulate filter data stored in ECM.

CAUTION:

Never perform “AFTER DPF REPLACEMENT” in “WORK SUPPORT” mode of “ENGINE” using CON-
SULT when oxidation catalyst with diesel particulate filter is not replaced with a new one. Diesel partic-
ulate filter may be damaged because regeneration is not performed at appropriate timing.

Work Procedure

INFOID:0000000010289699

1.

1.

Turn ignition switch ON.

2.

Select “AFTER DPF REPLACEMENT” in “WORK SUPPORT” mode of “ENGINE” using CONSULT.

3.

Touch “CLEAR” and wait a few seconds.

4.

Make sure that “CMPLT” is displayed on CONSULT screen.
