It uses an inductive data transmission between transponder (mounted inside the key) and the control unit. This data link is working with a carrier frequency of 125 kHz and uses amplitude modulation for transmitting data to the transponder. For the direction from the transponder to the control unit damping modulation with pulse duration coding is used. Functional description After switching on the ignition the immobilizer transmits a random number to the transponder. It calculates a result and transmits it back to the immobilizer. The result is checked and if it is correct, the engine will be released. After that, the immobilizer is switched off until another start is attempted. The longest period for transmitting 125 kHz is 3 seconds. Typical usage pattern (for Europe only) 15 operations in 24 hours with a transmission duration of 2 seconds. → total transmission duration of 1.25 seconds within 1 hour Transmitter ON 1.25 seconds / hour Transmitter OFF 3598.75 seconds / hour Duty Cycle: T ON / T (ON+OFF) x 100% = 1.25 / 3,600 x 100 % = 0.03 % Technical Data Carrier frequency: 125 kHz ± 5kHz Field strength: < 40 dBμA/m @ 10m Type of modulation ASK Number of channels: 1 Power supply: 12 V DC Type of battery: car battery Transmission range: 20 cm Siemens VDO Automotive AG SV C BC P2 RF TG File: S:\Postzula\OPEL\Immo2Gen\Func_Immobiliser_2Gen.doc Page 3 of 3 Block diagrams of the transmitter: ECU Ubat Transponder Antenne Kl. 30 Kl. 31 Kl. 15 Relais DWA W-Leitung Motor- kontrolleuchte K-Leitung Motorsteuerung Kl. 30 Kl. 30 510 Ohm Tester 10 kOhm Label design European Community: Siemens VDO 5WK4 7631 USA/CAN: Siemens VDO 5WK4 7631 IC: 267T-5WK47631 FCC ID:KR55WK47631 This device complies with part 15 of the FCC Rules and RSS-210.

The Rhode&Schwarz DC Power supply was connected to the DC input port of the 5WK4 7631 special connector. During preliminary emission tests the 5WK4 7631 was operated in continuous TRANSMITTING and READING mode for worst case emission mode investigation. Therefore, final qualification testing was completed with 5WK4 7631 operated in the both continuous modes. All tests performed with applicant typical voltage (12 Volts DC).
