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 illuminating the DPF warning indicator. 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 illuminating the DPF warning
indicator and illuminating the engine warning lamp. When the
vehicle is brought into the shop with the DPF warning
indicator illuminated, 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 13C Diesel Fuel
<4N1> - Troubleshooting
- Diagnosis Code Chart ).

Diagnosis
code P2463 should be set
if the engine-ECU
estimates that the PM
will more excessively be
accumulated after 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 indicator is
extinguished. The driving time is
approximately 20 minutes. It is all
right that the vehicle or the engine
stops during the driving.
- The forcible DPF regeneration must be
carried out (Refer to
).
