Advanced Measured Values

select item in menu:

IDEXXXXX-ENGXXXXXX - Diesel Particulate Filter: pressure difference sensor DIP_PF

TIP! For easier search in the menu, enter the code IDE, ENG or MAS into the "Filter" window

Start

increase rpm to XXXX rpm

wait X s

idling

required values =

Pressure - actual value (XXXX rpm) > Pressure - actual value (idling)

engine speed = X rpm
ignition = ON

Advanced Measured Values

select item in menu:

IDEXXXXX-ENGXXXXXX - Diesel Particulate Filter: pressure difference sensor - offset DIP_PF_[ADX]

TIP! For easier search in the menu, enter the code IDE, ENG or MAS into the "Filter" window
