SIEMENS VDO Automotive AG SV C CE AIS LF User Manual of the SIEMENS VDO Immobiliser and remote control system type HMC GH S:\postzula\DASOM\USA_CAN\Func_DASOM_USA.
SIEMENS VDO Automotive AG SV C CE AIS LF FUNCTIONAL DESCRIPTION 1. System Components The HMC GH System is a vehicle immobilisation and remote keyless entry (RKE) system. This system consists of a body controller module (BCM), an immobiliser antenna with corresponding transponder and a RKE transmitter. System Operation: The HMC GH System combines two sub-systems: an immobiliser system and a remote keyless entry system into one system that performs the functions of both modules.
SIEMENS VDO Automotive AG SV C CE AIS LF 2. Variants: Type designation 5WY8406 5WY8407 5WY8404 Difference Immobiliser antenna car line DASOM Immobiliser antenna car line PIC RKE transmitter 315 MHz The immobiliser antenna for car line PIC (type 5WY8407) uses the same schematic and pcb, but a slightly different assembly like the immobiliser antenna for car line DASOM (type 5WY8406). The assembly differs in the value of resistor R7: 5WY8407 uses 30.1Ohm and 5WY8406 uses 26.1Ohm 3.
