– Click the "Activate" button in the lower half of the screen.
– Observe value in lower part of screen. It must fluctuate be-
tween 0.65 ... 0.85 V and 3.30 ... 3.90 V (vacuum unit travels
to both end stops alternately).
If voltage OK:
– End basic setting procedure.

The service regeneration is used to estimate when the diesel
particulate filter must be renewed. Therefore, record the meas-
ured values of display group 108 prior to each service regener-
ation. This allows for preparing the renewal of the diesel partic-
ulate filter in a timely manner.

Diesel particulate filter has been renewed
If the diesel particulate filter is replaced by a new und unused
diesel particulate filter, the adaptation value for ash deposit
mass must be set to "0"
