Re: Certification for TRW Transmitter FCC ID: GQ4-61T IC: 1470A-42T REQUEST FOR CONFIDENTIALITY Pursuant to FCC 47 CRF 0.457(d) and 0.459 and IC RSP-100, Section 10, TRW requests that a part of the subject application be held confidential. TRW has spent substantial effort in developing this product and it is one of the first of its kind in industry. Having the subject information easily available to "competition" would negate the advantage they have achieved by developing this product. Not protecting the details of the design will result in financial hardship.

Block Diagram includes internal oscillator frequency information that the manufacturer considers to be proprietary. Permanent Confidentiality: TRW requests the exhibits listed above as permanently confidential be permanently withheld from public review. Short-Term Confidentiality (FCC Only): TRW requests the exhibits selected above as short term confidential be withheld from public view for a period of 45 days from the date of the Grant of Equipment Authorization and prior to marketing.

Operational Description

TRW Automotive February 06, 2013 TEE 24175 Research Dr. Farmington Hills, MI 48335-2642 Tel 248.478.7210 Fax 248.699.4241 RE: Certification for Chrysler MY2014 KL/DS Sensor FCC ID: GQ4-61T Canada IC: 1470A-42T Model #: 68157568AA, 68186572AA, 68186575AA PRINCIPLES OF CIRCUIT OPERATION The sensor incorporates an ASIC to measure the parameters within the tire. The ASIC then outputs the measured data in digital pulses. The digital data is frequency modulated. The transmitted signal uses Frequency Shift Keying (FSK). The carrier frequency of the sensor is 434 MHz typically. The worst case frequency shift of the carrier is 433.8615MHz for the low frequency and 433.9908MHz for the high frequency shift. The receiver bandwidth must be wide enough to pass the transmitter worst case frequency shifts. Reference Block Diagram in Exhibit 04.

Liepa Research Scientist Summary Tests for compliance with FCC Regulations, CFR 47, Part 15 and with Industry Canada RSS-210/Gen, were performed on a TRW, FCC ID: GQ4 -61T , IC: 1470A-42T . This device under test (DUT) is subject to the rules and regulations as a Transmitter. In testing completed on March 5 , 2013, the DUT tested met the allowed specifications for radiated emissions by 10.5 dB. Conducted emissions are not subject to regulation as the DUT is powered by a 12 VDC battery.

Introduction This TRW Transmitter was tested for compliance with FCC Regulations, Part 15, adopted under Docket 87-389, April 18, 1989 as subsequently amended, and with Industry Canada RSS-210/Gen,8. 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 2057A-1). 2. Equipment Used The test equipment commonly used in our facility is listed in Table 2.1. Except where indicated as a pre- test, monitoring, or support device; all equipment listed below is a part of the University of Michigan Radiation Laboratory (UMRL) quality system. This quality system has been established to ensure all equipment has a clearly identifiable classification, calibration expiry date, and that all calibrations are traceable to national standards.
