Type of Equipment : Tire Pressure Monitoring System (Receiver) Model No. : 23AAD Serial No. : Refer to Section 4, Clause 4.2 Receipt Date of Sample : August 6, 2010 Country of Mass-production : Japan and United States of America Condition of EUT : Engineering prototype (Not for Sale: This sample is equivalent to mass-produced items.) Modification of EUT : No Modification by the test lab 2.2 Product Description Model No: 23AAD (referred to as the EUT in this report) is the Tire Pressure Monitoring System (Receiver). 23AAD has 24 variations. For details of variations, see “Theory of Operation”. Feature of EUT : Tire Pressure Monitoring System is used for monitoring and indicating information of air pressure in vehicle’s tires. Transmitter sends receiver the data that are information of air pressure in vehicle’s tire through ANT1 or ANT2. The data also include temperature, battery voltage and identity code of transmitter. The receiver judges the data. If the data of air pressure and others are not normal condition, the receiver sends signal to a warning lamp. Then, the warning lamp warns drivers. AUTOMATIC LOCATION System is used for showing air pressure in vehicle’s each tire. The multiple antennas fitted to the vehicle transmit a low-frequency wave signal. The system automatically detects the wheel position involved in a pressure reading, even after tire rotation.
