(3) Warning Lamp Related to CDPF

▶
CDPF regeneration process (warning lamp NOT illuminated)
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.
2. 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
minutes to perform the CDPF regeneration process.
3. If the engine warning lamp on the instrument cluster blinks, the CDPF is overloaded. In this
case, perform the step 2.
Overload of CDPF (warning lamp blinking)
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.
