1. Product description
1.1 product summary
Immobilizer is a vehicle anti-theft system by electronic identification of owner.
The starter does not operate if a thief forces the door open and the engine started.

* The two reason why two reason for input frequency:
CPU can recognize when CPU recognition CODE used for immobilizer send
descripted data as radio frequency at transponder using binary code.
That's why we establish 134.2khz and 123.2khz for recognizing 0 or 1 at CPU

changed ENCRYPTION KEY in ASIC
whenever the Transponder receive
ENERGY or CHALLENGE from radio frequency.

② COIL ANTENNA
Ls (Inductance) : 444±20uH at 134.2KHz(equipped with STR'G LOCK)
coil antenna is supplied the energy and challenge to transponder
That is receiving and transmiited the signal from transponder to IMMOBILIZER
in the SHL(STEERING HANDLE LOCK)
③ IMMOBILIZER ECU
IMMO is operated the COIL ANTENNA.
The information ,that is Receiving signal from COIL ANTENNA compared
and analyzed, is transmitted to ENGINE ECU
④ ENGINE ECU
If the Igition is on, ENGINE ECU are received related with transponder
information from IMMOBILIZER ECU then perform engine starting or
impossible starting.
