When the anticipated PM
accumulation becomes larger in amount and reaches the
specified
level, the engine-ECU encourages the driver to drive under
the driving conditions required for
the DPF regeneration by showing the DPF warning mark on the
multi information display. When
the PM accumulated in the DPF reaches its clogged or damaged
level, the engine-ECU warns the
driver that the vehicle must be brought to the workshop by
showing the DPF warning mark in the
multi information display and illuminating the engine
warning lamp. When the vehicle is brought
into the shop with the DPF warning mark shown, service the
vehicle in accordance with the following
procedures.

The
engine-ECU estimates that the PM will
excessively be accumulated
in the DPF. At that time, the engine-ECU
should set the diagnosis codes (P1498 and
P2463). Carry
out the troubleshooting regarding the set
diagnosis codes (Refer to GROUP 13D, Diesel Fuel
-
Troubleshooting -
Diagnosis
Code Chart ).

note |
Diagnosis
code P2463 should be set
if the engine-ECU
estimates that the PM
will
more excessively be
accumulated after the
P1498 is set and the PM
will reach the level
where
the DPF cannot be
regenerated.

The
status is that the driver is advised to drive
the vehicle under
the driving conditions in which the DPF
automatic regeneration can be carried out
because it
is assumed that the PM is accumulated more than
the specified value in the DPF. In this case,
the DPF regeneration must be carried out using
one of the following two
methods:
- After the engine warm-up, the vehicle
must be driven at more than 40 km/h
until the DPF warning mark is
extinguished. The driving time is
approximately 20 minutes. It
is all right that the vehicle or the
engine stops during the
driving.
- Using the M.U.T.-III, the forcible DPF
regeneration must be carried out (Refer
to
).
