This information is then sent to a display unit. The receiver communicates tire status to the vehicle via a high speed CAN bus. The receiver shall be able to do diagnostics on the system to determine if the system needs to be serviced. When the ignition is in the run position, the receiver will activate the initiators to put the wheel-mounted sensors in normal operating mode, and start monitoring for RF data from the sensors. The time it takes the receiver to complete this operation is approximately 16 seconds. The receiver will also activate the initiators to request data from the sensors, if the receiver does not receive information from the sensors for more than 5 minutes. When the ignition is in the off position, the receiver will activate the initiators to put the wheel- mounted sensors in shut-down mode. The receiver will then turn itself off. This operation takes approximately 30 seconds. The initiator is part of the system used to detect the tire pressure sensors of the tires in a vehicle. Four initiators are used in each vehicle, one for each tire. They are located in or near the wheel well and are connected by wire harness to the central receiver. This central receiver sends a 125KHz waveform over the wire harness to the initiator where it is converted to a magnetic field that is broadcast to a sensor in the tire.

Liepa Test Report written by: Joseph D Brunett 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 TRW Inc. Transceiver, model/PN(s) 218143-119, 218143-120. This device is subject to Rules and Regulations as a Transceiver. In testing completed February 14, 2008, the device tested in the worst case met the allowed specifications for transmitter radiated emissions by 39.8 dB (see p. 7). Conducted emissions tests do not apply since the device is powered from a 12 VDC system.

Device Under Test 3.1 Identification The DUT was designed and manufactured by TRW Automotive Electronics, 2240 Cranbrook Drive, Auburn, New York, 13021. It is identified as: TRW Inc. Transceiver Model/PN(s): 218143-119, 218143-120 FCC ID: GQ4-40R IC: 1470A-12R 3.2 Variants The DUT contains a 125-160 kHz LF transmitter (initiator) and 315 MHz superheterodyne receiver. This report details the emissions relating to the transmitter portion of the device. The DUT is a 125 kHz Transceiver designed for an onboard automobile Tire Pressure Monitoring System (TPMS), and as such, it is powered from an automotive 12VDC source. Receiver and LF signal generating circuitry are housed in a plastic case approximately 3 by 5 by 1.5 inches. Coils are external. For testing, a generic harness was provided by the manufacturer. There are two variants of this device. Model 218143-119 was fully tested and represents one of two software variantions. Model 218143-120 is the other software variation, with slightly modified receiver processing for different tire pressure performance criteria. Both are electrically identical with identical RF. 3.3 Modes of Operation The DUT is designed to transmit over a range of frequencies between 125 and 160 kHz. The LF coil is tuned to the lowest operating frequency (125 kHz), and emissions were determined to be maximum at that frequency. All measurements are performed at with the device operating at 125 kHz. 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 Intention…
