Operational Description

General Description The Easy Key Gen 2 PASE system consi sts of a CID (Customer Identifi cation Device), an ECU (Electronic Control Unit), 5 passive ferrite antenn as, and one Active Antenna. The ECU transmits information to the CID through a 125kHz ASK carrier and the CID tran smits information to the ECU through an RF ASK carrier (315MHz for NA). The passive an tennas are used to transmit the 125kHz. The system allows for PASE (Passive Start and Entry) and well as RKE (Remote Keyless Entry). Passive entry is initiated by lifting the do or handle. The ECU will then ge nerate a 125kHz field, which the CID will read and respond back to the ECU via an RF response (315MHz for NA) The keypad on the CID can be used for RKE, where pushing a button tran smits an RF command (315MHz for NA). Passive start is initiated by pressing the start button inside the vehicle. As with passive entry, the ECU generates a 125kHz signal and the CID responds back with an RF signal (315MHz for NA). In addition to PASE and RKE, the system will also receive TPM signals. A backup for instances where RF is not possible is th rough limphome mode with the CID. In this case, the CID is placed near a designated Active Antenna which generates a 125kHz field . The CID will respond back by dampening the field through absorption modulation. The ECU provides power, ground, and data lines to the Active Antenna. Power Supply The ECU is powered by the vehicle battery.

Brunett Report approved by: _____________________ Valdis V. Liepa Research Scientist Summary Tests for compliance with FCC Regulations, Part 15, Subpart C, and for compliance with Industry Canada RSS-210/Gen, were performed on Siemens VDO Automotive transmitter, models 5WY7977 and 5WY8090. This device is subject to Rules and Regulations as a transmitter. In testing completed January 10, 2007, the device tested in the worst case met the allowed specifications for transmitter radiated emissions by 35.8 dB (see p. 7). Power line conducted emissions tests do not apply, since the device is powered from a 12 VDC vehicular system. University of Michigan Radiation Laboratory FCC Part 15, IC RSS-210/Gen - Test Report No. 415031-345 Page 2 of 12 1. Introduction Siemens model 5WY7977, 5WY8090 was tested for compliance with FCC Regulations, Part 15, adopted under Docket 87-389, April 18, 1989, and with Industry Canada RSS-210/Gen, Issue 6, September 2005. The tests were performed at the University of Michigan Radiation Laboratory Willow Run Test Range following the procedures described in ANSI C63.4-2003 "Methods of Measurement of Radio-Noise Emissions from Low-Voltage Electrical and Electronic Equipment in the Range of 9 kHz to 40 GHz". The Site description and attenuation characteristics of the Open Site facility are on file with FCC Laboratory, Columbia, Maryland (FCC Reg. No: 91050) and with Industry Canada, Ottawa, ON (File Ref. No: IC 2057). 2. Test Procedures and Equipment Used The pertinent test equipment commonly used in our facility for measurements is listed in Table 2.1 below.

Device Under Test 3.1 Identification The DUT is an automotive Passive Start and Entry (PASE) LF transmitter designed to communicate ID information to a customer identification device (CID) and is powered from an automotive 12 VDC source. The 125 kHz carrier is ASK modulated, the frequency generating circuitry is contained in the electronic control unit (ECU) module, and five ferrite loaded coils act as the antennas for the LF signal. The DUT was designed and manufactured by Siemens VDO Automotive, 4685 Investment Drive, Troy, MI 48098. It is identified as: Siemens VDO Automotive LF Transmitter Model: 5WY7977, 5WY8090 FCC ID: M3N5WY7977 IC: 267F-5WY7977 3.2 Models There is only a single model of the device. 3.3 Modes of Operation The device operates only in a single mode. However, the highest LF emissions occur when the in-dash LF coils are fired simultaneously as the key is placed in the vehicle ignition. All other coils are fired only individually, when a vehicle handle is lifted. 3.4 EMI Relevant Modifications No EMI Relevant Modifications were performed by this test laboratory. 4. Emission Limits 4.1 Radiated Emission Limits The DUT tested falls under the category of an Intentional Radiators and the Digital Devices, subject to Subpart C, Section 15.209; and Subpart B, Section 15.109 (transmitter generated signals excluded); and Subpart A, Section 15.33. The applicable testing frequencies with corresponding emission limits are given in Tables 4.1 and 4.2 below. As a digital device, it is exempt. Table 4.1.
