The
ECM monitors driving style and selects a suitable time to employ
regeneration. Cars driven
primarily
at idling speed and low load will attempt
to regenerate earlier than cars driven with
high
er
load
s
and
at
high
er
speed
s
.
F
or
regeneration to
occur
, a prolonged high exhaust temperature must be
obtained.
In the ev
ent
that the vehicle has been
driven in such a way that
regeneration is not possible
,
a diagnostic trouble code will
be registered,
DPF light and “Check Engine” indicator
will display
. A service regeneration
can be performed
using th
is
tool.
Before
initiating
a forced DPF
regeneration, c
heck the following items:
The fuel light is not on.
No DPF-relevant faults
are
stored
in system.
The vehicle has the correct spec engine oil.
The oil for diesel is not contaminated.
IMPORTANT
Before diagnosing a
vehicle
and attempting to perform an
emergency regeneration, it is important to obtain a full d
iagnostic log and
read out
of
relevant measured value blocks.
NOTE
1.
The DPF will not regenerate if the engine management light is on,
or
there is a faulty EGR valve.
2.
The ECU must be re-adapted when replacing the DPF and
adding the
fuel additive Eolys.
3.
If the vehicle needs to be driven in order to perform a DPF service,
ALWAYS have a second person help you. One person should drive the
vehicle while the other person observes the screen on the Tool. Trying
to drive and observe the Scan Tool at the same time is dangerous, and
could cause a serious traffic accident.
