3. CAUTIONS FOR DI ENGINE
1) Cautions for DI Engine
This chapter describes the cautions for DI engine equipped vehicle. This includes the water separation
from engine, warning lights, symptoms when engine malfunctioning, causes and actions.
DI Engine 1.
Comparatively conventional diesel engines, DI engine controls the fuel injection and timing electrically,
delivers high power and reduces less emission.
System Safety Mode 2.
When a severe failure has been occurred in a vehicle, the system safety mode is activated to protect the
system. It reduces the driving force, restricts the engine speed (rpm) and stops engine operation. Refer
to "Diagnosis" section in this manual.
Engine CHECK Warning Lamp 3.
The Engine CHECK warning lamp on the instrument cluster comes on when the fuel or
major electronic systems of the engine are not working properly. As a result, the

Water Separator Warning Lamp 4.
When the water level inside water separator in fuel filter exceeds a certain level (approx.
45 cc), this warning light comes on and buzzer sounds.
Also, the driving force of the vehicle decreases (torque reduction). If these conditions
occur, immediately drain the water from fuel filter.

1. SYSTEM DESCRIPTION
1) Overview
The lubrication system supplies oil to each lubrication section to prevent friction and wear and to remove
heat from the friction part. As the engine runs, frictional heat is generated on each lubrication section. If
this condition persists, the bearing can be burned and stuck.
In other words, it creates an oil film on each sliding surface to convert solid friction to liquid friction in
order to minimize wear and prevent temperature increasing on the friction part.
For the D20DTF engine with no oil pressure switch, the engine ECU receives the low engine oil level
signal from the oil level sensor and communicates with the instrument cluster through the CAN
communication to turn on the warning lamp.

(4) Maintenance
Make sure that the battery cables are firmly connected.
If the terminals are corroded, clean them with a wire brush or sandpapers.
Always disconnect the battery cables with the ignition key removed. When disconnecting the battery
cables with the ignition key turned to ON or ACC position, several electric units can be damaged
due to sudden voltage change.
Check the battery for crack, damage or fluid leaks. Replace it if necessary.
Wipe out the battery fluid on the battery surface using a rubber glove and a clean cloth wetted with
soapy water. -

If the charge warning lamp ( ) on the instrument cluster comes on while driving, there is a
malfunction in the charge system including the battery. Therefore, carrying out the system check is
needed.

5) ECO Cruise Control
The ECO cruise control system has nearly same functions with the auto cruise control system. It is an
automatic speed control system that maintains a desired driving speed without using the accelerator
pedal.
ECO cruise driving mode
The engine ECU controls the sharp acceleration and deceleration to improve the fuel economy.
The ECO cruise system is ready when pushing down the cruise control lever. At this moment, the
ECO indicator on the instrument cluster comes on.
The ECO cruise system operates when pulling up the cruise control lever.
To cancel the ECO cruise driving, push doen the cruise control lever. At this moment, the ECO
indicator on the instrument cluster goes off and the auto cruise starts to operate. -

(3) Warning Lamp Related to CDPF
CDPF regeneration process (warning lamp NOT illuminated) ▶
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.
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 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.

3) Input/Output for CAN communication
(1) Configuration of CAN (P-CAN/B-CAN)
CAN Topology communicate with system units. There are two types (P-CAN and B-CAN) of
communication according to the communication speed. Instrument cluster, BCM and diagnostic
connector use both types of communication. And, ECU, ABS & ESP, TCU, GCU, E-coupling and EPS
unit use P-CAN communication because it is faster than B-CAN. The terminal resistances are installed in
ECU and BCM.
