▶ Overload of CDPF (warning lamp blinking)
▶ Excessive overload of CDPF (warning lamp illuminated)
Actually, the DTC for the CDPF is generated more often by the component related to the CDPF
system, such as the differential pressure sensor, than by excessive soot in the CDPF.
1. If the CDPF cannot reach the regeneration tem-
perature due to low speed driving or other reason
during the regeneration process, the soot is con-
tinuously accumulated in the CDPF. When this
condition continues and the CDPF is overloaded with
soot, the engine warning lamp blinks to in-form this
situation to the driver.
2. In order to solve this problem, drive the vehicle at a
speed of approx. 80 km/h for 15 to 20 minutes to
perform the CDPF regeneration process.
3. If the engine warning lamp on the instrument clus-ter
blinks, the CDPF is overloaded. In this case, perform
the step 2.
1. If the vehicle is driven at a speed of 5 to 10 km/h for
an extended period of time, the soot accumu-lated in
the CDPF cannot be burnt as the CDPF cannot reach
the regeneration temperature. Then, an excessive
amount of soot can be accumulated in the CDPF.
2.
This case is much worse than the simple over-load of
the CDPF. To inform this to the driver, the engine
warning lamp comes on and the engine power is
decreased to protect the system.
3. To solve this problem, blow soot between the en-gine
and exhaust system several times and erase the
related DTC. Then, check if the same DTC is
regenerated again. If so, check the DTC related to the
differential pressure sensor.
