5) Warning Lamp Related to CDPF
CDPF regeneration process (warning lamp NOT illuminated) ▶
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.
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. W hen 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.
If the engine warning lamp on the instrument
cluster blinks, the CDPF is overloaded. In this
case, perform the step 2. 1.
2.
3.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-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
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. 1.

2) ECU Control
(1) Function
a. ECU Function
ECU receives and analyzes signals from various sensors and then modifies those signals into
permissible voltage levels and analyzes to control respective actuators.
ECU microprocessor calculates injection period and injection timing proper for engine piston speed
and crankshaft angle based on input data and stored specific map to control the engine power and
emission gas.
Output signal of the ECU microprocessor drives pressure control valve to control the rail pressure and
activates injector solenoid valve to control the fuel injection period and injection timing; so controls
various actuators in response to engine changes. Auxiliary function of ECU has adopted to reduce
emission gas, improve fuel economy and enhance safety, comforts and conveniences. For example,
there are EGR, booster pressure control, autocruise (export only) and immobilizer and adopted CAN
communication to exchange data among electrical systems (automatic T/M and brake system) in the
vehicle fluently. And Scanner can be used to diagnose vehicle status and defectives.
Operating temperature range of ECU is normally -40 to +85°C and protected from factors like
oil, water and electromagnetism and there should be no mechanical shocks.
To control the fuel volume precisely under repeated injections, high current should be applied instantly
so there is injector drive circuit in the ECU to generate necessary current during injector drive stages.
Current control circuit divides current applying time (injection time) into full-in-current-phase and hold-
current-phase and then the injectors should work very correctly under every working condition.
b. Control Function
Controls by operating stages
To make optimum combustion under every operating stage, ECU should calculate proper injection
volume in each stage by considering various factors.
Starting injection volume control
During initial starting, injecting fuel volume will be calculated by function of temperature and engine
cranking speed. Starting injection continues from when the ignition switch is turned to ignition
position to till the engine reaches to allowable minimum speed.
Driving mode control
If the vehicle runs normally, fuel injection volume will be calculated by accelerator pedal travel and
engine rpm and the drive map will be used to match the drivers inputs with optimum engine power. -

This is done periodically under certain operating conditions. When the resetting is finished, the new
minimum pulse value replaces the value obtained during the previous resetting. The first MDP value is
provided by the C3I. Each resetting then allows the closed loop of the MDP to be updated according to
the deviation of the injector.
B. Detection of leaks in the cylinders
The accelerometer is also used to detect any injector which may have stuck open. The detection
principle is based on monitoring the ratio. If there is a leak in the cylinder, the accumulated fuel self-
ignites as soon as the temperature and pressure conditions are favorable (high engine speed, high
load and small leak).
This combustion is set off at about 20 degrees before TDC and before main injection.
The ratio therefore increases considerably in the detection window. It is this increase which allows the
leaks to be detected. The threshold beyond which a fault is signaled is a percentage of the maximum
possible value of the ratio.
Because of the severity of the recovery process (engine shut-down), the etection must be extremely
robust.
An increase in the ratio can be the consequence of various causes:
Pilot injection too much
Main combustion offset
Fuel leak in the cylinder -
-
-
If the ratio becomes too high, the strategy initially restricts the pilot injection flow and retards the main
injection. If the ratio remains high despite these interventions, this shows that a real leak is present, a
fault is signaled and the engine is shut down.
C. Detection of an accelerometer fault
This strategy permits the detection of a fault in the sensor or in the wiring loom connecting the sensor
to the ECU.
It is based on detection of the combustion. When the engine is idling, the detection window is set too
low for the combustion caused by the main injection. If the ratio increases, this shows that the knock
sensor is working properly, but otherwise a fault is signaled to indicate a sensor failure. The recovery
modes associated with this fault consist of inhibition of the pilot injection and discharge through the
injectors.

▶ Speed Sensitive INT (Intermittent) Wiper
For STICS without rain sensor, perform the following operation:
1. Controls the wiper intermittent operation by the values from vehicle speed and volume.
Calculates and converts the Intermittent interval automatically by using the vehicle speed and INT
VOLUME when the ignition switch is in “ON” position and the INT switch is in “ON”
position (the engine is running).
The wipers are operated in vehicle speed sensitive mode when turning the INT switch to
“ON” position with the engine running or starting the engine with the INT switch positioned
“ON”.
Intermittent interval (at 0 km/h): 3 ± 0.5 ~ 19 ± 2 seconds -

2. Vehicle speed calculation
[Input the vehicle speed]
It is calculated by the numbers of input pulses for one second.
1 [pulses/sec] = 60 [km/h] x 60 [sec] / 637 pulses = 1.41 [km/h]
3. VOLUME calculation
Calculates the INT VOLUME with 5 grades as shown in the table in next page. -
4. Pause time calculation
Pause time: the duration that wipers are stopped at parking position
Elapsed time: the duration after the wiper motor started to operate from parking position
The pause time is calculated by the vehicle speed and VOLUME value as shown in the table in
next page. -
-
-
If the pause time is below 1.0 second, the wipers operate without pause.
If the pause time is over 1.5 seconds, the wipers operate intermittently. ·

▶All Door Lock Prevention Function when a Door is Opened
When a door is opened, all doors should be unlocked for 5 seconds if inputs LOCK signal. 1.
The LOCK signal means the central door locking (REKES, central door lock switch, knob switch)
except LOCK input by rear door knob.
After unlocking and opening only the driver’s door with remote control key under armed
mode (driver’s door is unlocked but passenger’s and rear doors are locked), only the
driver’s door generates unlock signal when trying to lock the driver’s door with the driver’s
door opened.
Above operations is regardless of key positions and have priority over the ignition key reminder
function. -
-
-
When the door is closed during unlock output for 5 seconds under item 1 condition, the unlock
output stops. 2.
All doors except tailgate and hood output “UNLOCK” for 5 seconds (T1) when the “LOCK”
signal is inputted (while the ignition key is removed and a of door is opened).
When the door is closed during unlock output for 5 seconds, the unlock output stops. -

8) Ignition Key Hole Illumination
The ignition key hole illumination comes on when opening the driver’s door or passenger’s
door while the ignition key is removed.
The ignition key hole illumination stays on for 10 seconds when closing the door after step 1.
The output stops when the ignition key is turned to “ON” position.
The output stops when receiving the lock signal from the remote control key (under armed mode). 1.

13) Theft Deterrent
(1) Description of Burglar Alarm Function
The “LOCK” output is “ON” when receiving the “LOCK” signal from transmitter while the
ignition key is removed and all doors are closed. The armed mode is activated when the door lock
switch is locked (theft deterrent horn output: once, hazard relay output: twice).
The theft deterrent horn and hazard relay outputs are “ON” when receiving the “LOCK” signal
from the remote control key again in armed mode (theft deterrent horn output: once, hazard relay
output: twice).
When receiving “LOCK” signal from the remote control key while any of doors is not closed,
only the “LOCK” output can be done and then activates the armed ready mode (without theft
deterrent horn and hazard warning flasher). At this moment, if the ignition key is in the ignition switch,
the door unlock switch is turned “ON” or the door lock switch is unlocked (after 0.6 seconds),
cancels the armed mode and activates the normal mode. However, in these cases, if closing the
door and locking the door lock switch, the theft deterrent horn outputs once and the hazard warning
flasher outputs twice and then activates armed mode.
When the door is not opened or the ignition key is not inserted into ignition switch for 30 seconds
after receiving “UNLOCK” signal, outputs “LOCK” and then activates armed mode (RELOCK
operation). Also, at this moment, the system outputs the theft deterrent horn and hazard warning
flasher.
The armed mode will not be activated except above conditions.
Ex) The armed mode will not be activated when the door is locked by the ignition key. 1.
