Siemens VDO Automotive AG SV C BC P2 RF TG User Manual of the Siemens VDO OPEL Immobiliser type 5WK4 7631 File: S:\Postzula\OPEL\Immo2Gen\Func_Immobiliser_2Gen.doc Page 1 of 3 Siemens VDO Automotive AG SV C BC P2 RF TG System description of the Opel Immobilizer 2nd Generation Redesign The immobilizer 2nd generation prevents drive away car theft powered by its own engine without having a valid key. 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: TON / T (ON+OFF) x 100% = 1.25 / 3,600 x 100 % = 0.03 % Technical Data Carrier frequency: Field strength: Type of modulation Number of channels: Power supply: Type of battery: Transmission range: 125 kHz ± 5kHz < 40 dBµA/m @ 10m ASK 12 V DC car battery 20 cm File: S:\Postzula\OPEL\Immo2Gen\Func_Immobiliser_2Gen.doc Page 2 of 3 Siemens VDO Automotive AG SV C BC P2 RF TG Block diagrams of the transmitter: Transponder Ubat 125kHz Kl. 30 Relais Antenne Kl. 31 Kl. 15 DWA Motor- Kl. 30 ECU kontrolleuchte Kl. 30 10 kOhm 510 Ohm W-Leitung K-Leitung Motorsteuerung Tester 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.
