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.

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. -

(14) Immobilizer control
A. Overview
The Immobilizer System provides an additional theft deterrent to the vehicle in which it is installed and
prevents it from being started by unauthorized persons. The transponder integrated in the key and the
engine control unit have the same code. When the ignition key with the integrated transponder is turned
to the ON position, the ECU (Engine Control Unit) checks the crypto code of the key and, if correct,
allows the vehicle to start the engine.
For details, refer to Chapter "Immobilizer".

Key approval process ▶
When turning the ignition switch to ON position, the power is supplied to BCM and ECU. ECU
communicate with the immobilizer key to check if it is valid crypto code. If it is valid, ECU start to control
the engine when turning the ignition switch to START position. The system has 10 seconds of valid time-
out period. If the engine does not start in this period, the key approval process should be done again.

▶Ignition Key Hole IlluminationThe ignition key hole illumination comes on when opening the driver's door or passenger's doo
r
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 the "ON" position.
The output stops when receiving the lock signal from the remote control key and entering armed
mode.

4) How to Code REKES Key
If you replace the REKES key or immobilizer key to new one, you should c\
ode the REKES key using the
diagnostic device. (maximum 5)Connect the diagnostic device to the vehilce and se lect the vehicle type and system (RK-STICS).
When the following screen is displayed, select 'REMOCON CODING'.
1.
Remove the remote control key from the ignition key box and press 'Next'\
. Press the door UNLOCK
(PANIC) button on the remote control key once (for approx. 2 seconds \
or longer).

5) How to Register Transponder
Insert the ignition key into the key cylinder and turn it to the "ON" po\
sition.
Select the vehicle type and system (immobilizer) on the diagnosis program.
Select the Transponder registration menu and enter the password. (initi\
al value is "0000") Select "Next".
