(3) Warning Lamp Related to CDPF

CDPF regeneration process (warning lamp NOT illuminated)

Overload of CDPF
(warning lamp blinking)
Blinking
1. If the CDPF cannot reach the regeneration
temperature due to low speed driving or other
reason during the regeneration process, the
soot is continuously accumulated in the CDPF.
When this condition continues and the CDPF is
overloaded with soot, the engine warning lamp
blinks to inform this situation to the driver.
In order to solve this problem, drive the vehicle
at a speed of approx. 80 km/h for 15 to 20
2. minutes to perform the CDPF regeneration
process.
If the engine warning lamp on the instrument
cluster blinks, the CDPF is overloaded. In this
3. case, perform the step 2.
The CDPF system enters the regeneration mode
when the driving distance becomes approx. 600
to 1,200 km (may differ by the driving condition
and driving style). Then, the engine ECU
performs the CDPF regeneration operation.
However, the driver is not informed with this
operation by any engine warning lamp or
vehicle signal, so he/she may not detect this
operation. The control logic at the post-
injection dur-ing the regeneration process is to
increase the fuel injection volume and control
the intake air volume (by the throttle body) in
order to increase the temperature of the exhaust
gas. The driver may not feel any particular
difference from the vehicle.
Excessive overload of CDPF
(warning lamp illuminated)
Illuminating
1. If the vehicle is driven at a speed of 5 to 10
km/h for an extended period of time, the soot
accumulated in the CDPF cannot be burned as
the CDPF cannot reach the regeneration
temperature. Then, an excessive amount of
soot can be accumulated in the CDPF.
This case is much worse than the simple over-
2. 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.
To solve this problem, blow soot between the
3. engine 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.
