INSPECTION
Wrap tin foil around the end of the voltmeter test lead to prevent damaging the heater line. Apply finger pressure
on the tin foil, moving the tin foil along the grid line to check for open circuits.
1.Turn on the defogger switch and use a voltmeter to measure the voltage of each heater line at the glass center
point. If a voltage of approximately 6V is indicated by the voltmeter, the heater line of the rear window is
considered satisfactory.
2.If a heater line is burned out between the center point and (+) terminal, the voltmeter will indicate 12V.
3.If a heater line is burned out between the center point and ( - ) terminal, the voltmeter will indicate 0V.

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).
SMARTRA unit
The SMARTRA carries out communication with the built- in transponder in the ignition key. This wireless
communication runs on RF (Radio frequency of 125 kHz). The SMARTRA is mounted behind of the crush pad under
panel close to the antenna coil for RF transmission and receiving.
The RF signal from the transponder, received by the antenna coil, is converted into messages for serial
communication by the SMARTRA device. And, the received messages from the PCM(ECM) are converted into an RF
signal, which is transmitted to the transponder by the antenna.
The SMARTRA does not carry out the validity check of the transponder or the calculation of encryption algorithm. This
device is only an advanced interface, which converts the RF data flow of the transponder into serial communication to
the PCM(ECM) and vice versa.
TRANSPONDER (Built-in keys)
The transponder has an advanced encryption algorithm. During the key teaching procedure, the transponder will be
programmed with vehicle specific data. The vehicle specific data are written into the transponder memory. The write
procedure is once only; therefore, the contents of the transponder can never be modified or changed.
Antenna coil
The antenna coil (A) has the following functions.a. The antenna coil supplies energy to the transponder.
b. The antenna coil receives signal from the transponder.
