DESCRIPTION
The immobilizer system will disable the vehicle unless the proper ignition key is used, in addition to the currently
available anti- theft systems such as car alarms, the immobilizer system aims to drastically reduce the rate of auto
theft.
1. SMARTRA type immobilizer
a. The SMARTRA system consists of a transponder located in the ignition key, an antenna coil, a SMARTRA unit,
an indicator light and the PCM(ECM).
b. The SMARTRA communicates to the PCM(ECM) (Engine Control Module) via a dedicated communications line.
Since the vehicle engine management system is able to control engine mobilization, it is the most suitable unit
to control the SMARTRA.
c. When the key is inserted in the ignition and turned to the ON position, the antenna coil sends power to the
transponder in the ignition key. The transponder then sends a coded signal back through the SMARTRA unit to
the PCM(ECM).
d. If the proper key has been used, the PCM(ECM) will energize the fuel supply system. The immobilizer indicator
light in the cluster will simultaneously come on for more than five seconds, indicating that the SMARTRA unit
has recognized the code sent by the transponder.
e. If the wrong key has been used and the code was not received or recognized by the PCM(ECM) the indicator
light will continue blinking for about five seconds until the ignition switch is turned OFF.
f. If it is necessary to rewrite the PCM(ECM) to learn a new key, the dealer needs the customer's vehicle, all its
keys and the Scan tool (pro) equipped with an immobilizer program card. Any key that is not learned during
rewriting will no longer start the engine.
g. The immobilizer system can store up to four key codes.
h. If the customer has lost his key, and cannot start the engine, contact motor service station.
COMPONENTS OPERATIONS
PCM (Power Train Control Module)
1. The PCM(ECM) carries out a check of the ignition key using a special encryption algorithm, which is programmed
into the transponder as well as the PCM(ECM) simultaneously. Only if the results are equal, the engine can be
started. The data of all transponders, which are valid for the vehicle, are stored in the PCM(ECM).

DESCRIPTION
When reversing, the driver is not easy to find objects in the blind spots and to determine the distance from the object.
In order to provide the driver safety and convenience, back warning system will operate upon shifting to "R" Ultrasonic
sensor will emit ultrasonic wave rearward and detect the reflected wave. Control unit will calculate distance to the
object using the sensor signal input and output buzzer alarm in three steps (first, second and third alarm).
ALARM RANGE
Upon detecting an object at each range out of 3 ranges as stated below within the operation range, it will generate
alarm.
First alarm : Object comes near to the sensor located at the rear of vehicle, within 81- 120cm ± 15cm
Second alarm : Object comes near to the sensor located at the rear of vehicle, within 41- 80cm ± 10cm
Third alarm : Object comes near to the sensor located at the rear of vehicle, within 40cm ± 10cm
a.Time tolerance of the above waveform : Time ± 10%
b. At nearer distance than 40cm, detection may not occur.
c. Alarm will be generated with vehicle reversing speed 10km/h or less.
For moving target, maximum operation speed shall be target approach speed of 10km/h.
d. When the vehicle or the target is moving, sequential alarm generation or effective alarm may be failed.
e. False alarm, or failure of the alarm to trigger may occur in the following conditions.
a. Irregular road surface, gravel road, reversing toward grass.
b. Horn, motor cycle engine noise, large vehicle air brake, or other object generating ultrasonic wave is near.
c. When a wireless transmitter is used near to the sensor.
d. Dirt on the sensor.
e. Sequential alarm may not occur due to the reversing speed or the target shape.

Transmit ultrasonic wave to the sensors, boost input signal, and detect wave.
Waveform will be found, oscillating for a certain period of time.1. Waveform for a normal sensor connection
2.Waveform for a failed sensor connection
Sensor connection will be checked for oscillating period of input signal 3V. If oscillating period is more than
0.8ms, it is normal.
a. Left sensor failure : beep- beep- beep
b. Right sensor failure : beep beep- beep beep- beep beep
c. Rear - right sensor failure : beep beep beep- beep beep beep- beep beep beep
d. Right side sensor failure : beep beep beep beep- beep beep beep beep- beep beep beep beep
WARNING
1.Range detected by back sensors is limited.
Watch back before reversing
2. There is a blind spot below the bumper. Low objects (for example boundary barrier) may be detected from minimum
1.5m away unable to detect at nearer.
3. Besides there are some materials unable to be detected even in detection range as follows.
(1) Needles, ropes, rods, or other thin objects.

Operation principle
The sensor emits ultrasonic wave to the objects, and it measures the time until reflected wave returns, and calculates
the distance to the object.
Distance detection type
Direct detection type and indirect detection type are used together for improving effectiveness of the detection.
1. Direct detection type: One sensor transmits and receives signals to measure the distance.
2.Indirect detection type: One sensor transmits signals and the other sensor receives the signals to measure the
distance.
Measurement principle
Back warning system (BWS) is a complementary device for reversing. BWS detects objects behind vehicle and
provides the driver with buzzer alarm finding objects in a certain area, using ultrasonic wave propagation speed and
time.
The propagation speed formula of ultrasonic wave in air is following :
v=331.5 + 0.6t (m/s)
v=ultrasonic wave propagation speed
t=ambient temperature
The basic principle of distance measurement using ultrasonic wave is :
