6) CDPF Over Load (Notice of Beginning CPF Regeneration Mode
- P1430)
The CDPF system enters the regeneration mode when the mileage is around 600 ~ 1,200
km, depending on the driving condition and driving habits. At this moment, the ECU
performs the CDPF regeneration process; however, the driver may not notice anything
because there is no engine warning or other signals indicating such process.
The control logic in the regeneration process is to increase the exhaust gas temperature by
increasing the fuel injection during post injection process and controlling the intake ai
r
amount(throttle body), and no significant change can be noticed in the vehicle condition.
The engine CHECK lamp flashes but there is no decrease in engine torque.
The engine CHECK lamp flashes to inform the driver when there is an over load due to soot
accumulation because the regeneration temperature cannot be reached due to low speed,
even though CDPF regeneration is in process.
The CDPF regeneration process must be completed by driving for 15-20 minutes at a speed
higher than 80 km/h to solve this problem.
The engine CHECK lamp flashes when CDPF is over loaded; therefore, 4) above must be
performed in this case. 1.

7) CDPF's Excessive Soot Accumulation (P0432)
When the vehicle is driven at a low speed (5-10 km/h) for a long time or long distance, the
soot over accumulates inside the CDPF and the combustion temperature cannot be reached
even by performing the soot combustion process. In this case, this DTC is generated.
This is more serious situation than the CDPF over load condition. Therefore, the engine
power is decreased to protect the system and the engine CHECK lamp is turned on.
Blow the soot between the engine and the exhaust system several times and clear the DTC
to solve this problem. If the same DTC is generated again, check the system according to
the DTC description related to the differential pressure sensor.
* This DTC is actually generated mostly due to the related system malfunction, such as
differential pressure sensor malfunction. 1.

STICS
If the washer operating signal is inputted while the wipers are operating in intermittent or
AUTO mode, the system stores the previous intermittent interval and operates the washe
r
coupled wiper. After then, the wiper operation returns back to intermittent or AUTO mode
with the stored operating interval. 3.

(2) Rain Sensor Coupled Wiper
If equipped with RE-STICS rain sensor, has following operation system.
System layout ▶
This vehicle has a different wiper control logic compared to other models. As shown in the
system diagram, the rain sensor unit does not control wiper directly. The rain sensor unit sends
infrared rays signal through LED and then receives it with photo diode and then sends the
returned signal to STICS and the STICS controls the wipers directly.
For more details, refer to rain sensing wiper section in this manual.

Rain sensing operation point ▶
The wiper relay is turned on and the wiper motor runs one cycle when the ignition key is
turned to “ON” position (while the wiper switch is in “AUTO” position).
The wiper relay (LO) is turned on and the wiper motor runs one cycle when changing the
wiper switch to “AUTO” position from any other positions (while the ignition key is in
“ON” position). When the wiper switch is turned to “AUTO” position again from other
positions, the system drives the wiper relay (LO) to run the wiper motor one cycle only when
the rain sensor detects the “Rain Detected” signal. 1)
2)
Rain sensing sensitivity control ▶
The wiper relay is turned on and the wiper motor runs one cycle when the volume sensitivity is
increased (ex: from 0 to 1) (while the ignition key is in “ON” position, the wiper switch is
in “AUTO” position, and the wiper motor is in “Parked” position). However, the wiper
motor can be operated only when the rain sensor detects the “Rain Detected” signal.
* If the volume sensitivity is changed more than 2 stages within 2 seconds, the wiper motor runs
only one cycle.

Defective rain sensor ▶
The wiper relay (LO) is turned on and the wiper motor runs one cycle when the wipe
r
sensitivity is changed to 2 from 3 during receiving the malfunction signal (1) from the rain
sensor (while the ignition key is in “ON” position and the wiper switch is in “AUTO”
position). 1)
The wiper relay (LO) is turned on and the wiper motor runs one cycle when the wiper
sensitivity is changed to 3 from 4 during receiving the malfunction signal (2) from the rain
sensor (while the ignition key is in “ON” position and the wiper switch is in “AUTO”
position). 2)
