Conditions:
- engine temperature MIN XX°C (Advanced Measured Values IDEXXXXX-coolant temperature)
- engine speed = idling
wait XX s
connect with the control unit XX - engine
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
required value =
X hPa
if values are not achieved, check part:
- tube to sensor (tightness of line, mistaking)
- pressure difference sensor DPF - line
- pressure difference sensor DPF
engine speed = X rpm
ignition = ON
disconnect from power supply part: pressure difference sensor DPF
connector -> terminal X,X,X
measure voltage between terminals X,X - , required value = XV ± X.XV
measure voltage between terminals X,X - , required value = X.XXV ± X.XXV
end
