Type of Equipment : Remote Keyless Entry System and TPMS (Receiver) Model No. : 23AAT Serial No. : Refer to Section 4, Clause 4.2 Receipt Date of Sample : August 8, 2014 Country of Mass-production : Japan, 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: 23AAT (referred to as the EUT in this report) is the Remote Keyless Entry System and TPMS (Receiver). 23AAT has 15 variations. For details of variations, see “Theory of Operation”. Feature of EUT: <RKES mode> RKE System is mainly used for locking or unlocking the doors of the vehicle. The transmitter sends a radio wave signal while the button is pushed. The receiver becomes active in response to the signal from the transmitter. <TPMS mode> Tire Pressure Monitoring System is used for monitoring and indicating information of air pressure in vehicle’s tires. Transmitter sends receiver the data that informs air pressure in vehicle’s tire to the receiver. The data also includes the information of temperature, battery voltage and identity code of transmitter. The receiver judges the data, and if the data of air pressure and others is not in a normal condition, the receiver sends signal to a warning lamp. Then, the warning lamp warns drivers.
