D. PTC operation process
The PTC operating condition (ON) is controlled in two steps.
Basically, the engine ECU controls the relay to supply the power to PTC according to the coolant
temperature sensor and ambient temperature sensor.

2) Fuel Injection During CDPF Regeneration
3) Warning Lamp Related To CDPF
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 during 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.
