SIEMENS VDO Automotive AG SV C BC P2 RF TG IC: 267T-5WK49182 FCC ID:KR55WK49182 File: I:\POSTZULA\Suzuki\Technical Documentation\Functional_description_Gasoline.doc Page 2 of 4 FUNCTIONAL DESCRIPTION System Components The Suzuki Gasoline immobilization system consists of the immobilizer antenna, a trans-ponder and the Engine control unit. The immobilizer antenna is located on the vehicle’s ignition lock. The transponder is located within the ignition key. The transponder is magneti-cally coupled to the immobilizer antenna. The immobilizer antenna is connected to vehicle power and to vehicle ground via a wiring harness and to the Engine control unit via serial interface. For the illumination, a side LED which is connected to a light pipe is used. The LED is pow-ered externally via two resistors. System Operation This immobilizer system is a passive immobilization system. The immobilizer antenna uses a magnetic couple to read the transponder’s identification code. The immobilizer compares the identification code received from the transponder via immobilizer antenna with identification codes stored in its non-volatile memory. If the identification code from the transponder matches one of the identification codes stored in memory, the immobilizer sends a “Valid Key” message to the Engine Management System controller. If there is no match, the im-mobilizer sends an “Invalid Key” message to the Engine Management System controller. This causes the Engine Management System to turn off the engine.
