Functional Description - Comfort Access System (CA) 1.1 General functional description The CA-system enables convenient utilization of the vehicle. To use the vehicle, the driver only needs to take the key along with him/her. The vehicle communicates with the system inductively via antennas. These antennas are located in the rear bumper, in the trunk, of the backlite shelf and in the interior. These antennas are driven inductively with a frequency of 125 kHz. The system's range is limited in a defined fashion by damping the body sheet metal. In the vehicle interior, the ranges of the various antennas overlap, which enables location of the key. 1.2 Passive access control Controlled by TAGE (outside door handles electronic) 1.3 Passive Go (start/stop) The system provides the function which enables starting/stopping the engine without key actuation. The prerequisite for starting the vehicle is a key allocated to the vehicle, which is taken along by the user and is clearly inside the vehicle. By actuating the starting device, the driver starts the identification process, i.e. the PGS control unit issues a request for a valid key inside the vehicle. The key returns an appropriate response to the PGS control unit. In case of successful identification of the key, the vehicle is started and the immobilizer is deactivated. 2.

BMW_PGS2_E8x_Homolog_e.doc Page 5 / 5 SV C BC P2 HW Pase 01.03.2004 CONFIDENTIAL H.Schmittschmitt 7.1 FCC Declaration FCC ID LX8PGS This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept interference received, including interference that may cause undesired operation. 8. Power up of test samples The test setup consists of the following components: • Control unit: PGS2; 5WK4 9135 • Wiring harness: Control unit ↔ bumper antenna and power supply • Antennas: 1 bumper antenna 5WK4 9133 • Power Supply: 14VDC or car battery (not supplied) The bumper antenna will represent the max. allowed inductive load, which the control unit can supply. 8.1 Test configuration and operation Connect the wiring harness to the control and the bumper antenna. More precise allocation of connector - socket is not necessary, as all connections are mechanical or color-coded. The entire test setup is connected to power via the two banana jacks on the wiring harness. Banana jack, red = 14VDC or car battery Banana jack, blue = GND (ground) The power consumption in case of operation amounts to max. 10A. If the power supply is connected the control unit begins to operate. The connected antenna will transmit the carrier frequency with a duration of approximately 40ms at intervals of 500ms. The transmitter power of the control unit is adjust by 100%. This procedure does not correspond to the standard mode of operation! This procedure is only used to simplify emission measurements. Caution: Any changes or modifications not expressly approved by the party responsible forcompliance could void the user's authority to operate the equipment.
