There are no hardwired electrical connections to the TPM Sensors. The TPM Sensor monitors the pressure and the temperature inside the tire and transmits the information to a TPM receiver located in a vehicle by way of an Ultra High Frequency (UHF) band wireless signal. The TPM Sensor receives programming and diagnostic requests by way of a Low Frequency (LF) band wireless signal.

Liepa Report Approved by:__________________________ Valdis V. Liepa Test report written by: Valdis V. 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: GQ4-51T, IC: 1470A-32T. This device under test (DUT) is subject to the rules and regulations as a Transmitter. In testing completed on November 22, 2011, the DUT tested met the allowed specifications for radiated emissions by 8.5 dB. Conducted emissions are not subject to regulation as the DUT is powered by a 3 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, Issue 8, December 2010. 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.
