DANGER!
If soot loading in display zones 2 and 3 exceeds 35 g, the
intake manifold is locked. In this case, NEVER start a re-
generation.
If soot loading in display zones 2 and 3 is between 30.0 ... 35 g:
– Perform a regeneration of the diesel particulate filter
; regeneration of diesel particulate filter.
– The vehicle manufacturer may specify a different value. Ob-
serve the specifications of the vehicle manufacturer.
If the ash deposit mass in display zone 1 exceeds 500 ml or the
soot loading in display zones 2 or 3 exceeds 40.0 g:
– Exit diagnosis function.
– Switch off ignition.
– Renew diesel particulate filter.
3.12 Regeneration of diesel particulate filter,
engine codes CJDA, CJDD
Note
◆
A regeneration of the diesel particulate filter can only be per-
formed if the coolant temperature is at least 80°C and the
exhaust gas temperature ahead of the diesel particulate filter
is at least 161°C.
◆
The regeneration takes 20 min.
– Start engine and run at idling speed.
– Connect vehicle diagnostic tester, and select engine control
– Select diagnosis function “011-Read measured value block”.
– Select “Display group 001”.
Indicated on display:
– Check coolant temperature in display zone 4. Specification:
at least 80°C.
– Increase engine speed to above 1500 rpm.
Do not continue with test until coolant temperature of 80°C has
been reached.
– Press
←
button (back).
– Select “Display group 100”.
Indicated on display:
– Check exhaust gas temperature value from exhaust gas
temperature sender 3 -G495- (exhaust gas temperature
sender ahead of diesel particulate filter) in display zone 1.
Specification: at least 161°C.
Do not continue with test until specified exhaust gas tempera-
ture ahead of diesel particulate filter has been reached.
