PCM (Power Train Control Module)
| 1. |
The PCM(ECM) (A) 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).
ERN (Encrypted Randorm Number) value between EMS and encrypted
smartra unit is checked and the validity of coded key is decided
by EMS.

ENCRYPTED IMMOBILIZER unit (A)
The IMMOBILIZER carries out communication with the built-in transponder
in the ignition key. This wireless communication runs on RF (Radio frequency
of 125 kHz). The IMMOBILIZER is mounted behind of the crash pad close to
center cross bar.
The RF signal from the transponder, received by the antenna coil,
is converted into messages for serial communication by the IMMOBILIZER 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 IMMOBILIZER 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 (A) 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.
| - |
The antenna coil supplies energy to the transponder.
|
| - |
The antenna coil receives signal from the transponder.
|
| - |
The antenna coil sends transponder signal to the IMMOBILIZER.
It is located directly in front of the steering handle lock.

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 ...
