This information is then sent to a display unit. The receiver shall directly illuminate the display with discrete light emitting diode (LED) drivers. The receiver can initiate the transmitter to send configuration data or pressure and temperature data by activating the low frequency initiator mounted in the wheel well. This activation can also be used to determine if a new transmitter has been placed in the TPM. The receiver shall be able to do diagnostics on the system to determine if the system needs to be serviced. The receiver can also place the transmitter in a low current mode when the ignition is off to prolong the battery life of the transmitter. When the ignition is turned on, the receiver should put the transmitter in to a high update rate mode and immediately get the tire and pressure information from the transmitter. Activating the transmitter with the low frequency initiator does the mode changes.

The microprocessor sends low frequency (125KHz) amplitude-shift-keying data to the initiator via a signal conditioning circuit and wire harness. The initiator, which is located in the wheel well, amplifies this signal and transmits data to the tire pressure sensor located in the wheel. The sensor responds with data modulated at 315MHz. The receiver demodulates this 315MHz signal to receive the data sent from the pressure sensor. Tire pressure problems are reported to the driver via light emitting diodes on the dashboard. The receiver illuminates the LEDs with LED driver circuitry.

October 24, 2003 RE: TRW Inc. FCC ID: GQ4-3QR The following is in response to comments made on the above referenced Application. Q: It is not certain if the labeling should be placed as indicated. TRW wants to place the labels as indicated primarily for identification, marketing, and inventory reasons. Since the RX is entirely contained in the control module, its label will be on main module. For the LF transmitter, the circuitry is split between the control module and the “initiator” module. Here, TRW requests that the label be placed on the “initiator” module because, in the users/manufacturers view, the initiator is this module and the transmitting coil is contained therein. Essentially, the labels are placed as such to avoid confusion and provide a means of identifying the RX and LF TX separately to the customer. Both modules will be sold together as part of the same model, 39360-S3V-A0.

Courtney Valdis V. Liepa Valdis V. Liepa Research Scientist Summary Tests for compliance with FCC Regulations Part 15, Subpart B, and Industry Canada RSS-210, were performed on TRW model 39350-S3V-A0. This device is subject to the Rules and Regulations as a Receiver. As a Digital Device it is exempt, but such measurements were made to assess the receiver's overall emissions. In testing completed on 7-Jul-03, the device tested in the worst case met the allowed FCC (Class B) specifications for radiated emissions by 6.7 dB (see p. 6). The conducted emissions tests do not apply, since the device is powered from a 12 VDC system. 2 1. Introduction TRW model 39350-S3V-A0 was tested for compliance with FCC Regulations, Part 15, adopted under Docket 87-389, April 18, 1989, and with Industry Canada RSS-210, Issue 5, November, 2001. The tests were performed at the University of Michigan Radiation Laboratory Willow Run Test Range following the procedures described in ANSI C63.4-1992 "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 Procedure and Equipment Used The pertinent test equipment commonly used in our facility for measurements is listed in Table 2.1 below.

Configuration and Identification of Device Under Test The DUT is a 315 MHz superheterodyne receiver, designed for onboard automobile security/convenience applications, and as such, it is powered from an automotive 12 VDC source. It is housed in a plastic case approximately 6 by 4 by 1.5 inches. Antenna is internal. For testing, a generic harness was provided by the manufacturer. In the receiver digital section, the decoding, signal processing, etc. are performed by a microprocessor timed by a 10 MHz oscillator. The RFIC used in this receiver operates at 2 x LO frequency of 651.4 MHz, the LO is generated through the use of a divider, resulting in a LO of 325.7 MHz and IF of 10.7 MHz. The DUT was designed by TRW, Inc., 24175 Research Drive, Farmington Hills, MI 48335-2642. It is identified as: TRW Receiver Model: 39350-S3V-A0 FCC ID: GQ4-3QR IC: 1470A-2R 3.1 Modifications Made There were no modifications made to the DUT by this laboratory. 4. Emission Limits The DUT tested falls under Part 15, Subpart B, "Unintentional Radiators". The pertinent test frequencies, with corresponding emission limits, are given in Tables 4.1 and 4.2 below. 4.1 Radiated Emission Limits Table 4.1.
