Abstract This Specification is described an Anti-Theft System for automotive. 2. Overview This Immobilizer System allows for an engine starting only if correct mechanical key as well as electronical matching by RF signal. 3. System Configuration COIL ANT. ENERGY & CHALLENGE SHL TRANSPONDER SERIAL NUMBER와 RESPONSE IMMOB.ECU RELAY K-LINE ANSWER CODE DIAG. TESTER REQUEST CODE ENGINE ECU (주)신창전기 (주)신창전기 3.1. TRANSPONDER ASIC CONDENSER COIL After energyzing by RF signal from immobilizer, Transponder receives challenge signals and then transmits response calculated by its own algorithm which is stored in ASIC. 12 3.2. COIL ANTENNA Ls (Inductance) : 447uH ± 20uH (IGN Lock barrel installation state) Rs (Resistance) : ?Ω Low Q(Quality factor) : 25Low Antenna coil works as a medium for RF communication between transponder and immobilizer. It is located on the ignition lock barrel. 3.3. IMMOBILIZER ECU It drives coil antenna and analyze data from transponder. And also it transmit answer code to ECU. 3.4. ENGINE ECU(ECM or EMS) ECU analyzes the anwer data from immobilizer and then ECU decides to engine start or not 3.5. DIAGNOSTIC TESTER It has diagnosis function, key teaching to immoblizer and entering user password. 3.6. STATUS INDICATOR It indicates the status of immbilizer such as lock or unlock. (주)신창전기 4.3. GENERAL FUNCTION. 4.3.1. Communication specification for ID KEY CONTROLLER(ICK) and T/P TRANSPONDER ID CONTROLLER Operating is possible in reset state Beginning in valid condition to read Transponder 1) Transmit burst signal(50msec) 2) Transmit 40bit's Challenge Energy & 1) Charge energy to inner Challenge Condenser by burst signal 2) Receive challenge ICU calculates response in 3) Processing encryption response from transponder advance before receiving using by Encryption Key Response 4) Transmit response to ICU FSK modulation Comparison with responses 1) Correct : Permit starting 2) Incorrect : Recheck T/P (MAX : For 1sec ) 4.3.2. Transponder Code Reading Procedure ① IKC transmits challenge data to the transponder and then check the receiving response from it. ② IKC challenges again in case of incorrective response. ③ If the response is correct, IKC does not send challenge signal any more. If response is not correct, IKC sends challenge again up to 5 times until response is correct. 4.3.3.

Antenna shall be mounted in such a manner to minimize the potential for human contact during normal operation. The antenna should not be contacted during operation to avoid the possiblility of exceeding the FCC radio frequency exposure limit. The minimum separation distance of 20cm from the antenna to the body of user required."
