Modification of EUT : No Modification by the test lab 2.2 Product Description Model No: 23AAE (referred to as the EUT in this report) is Remote Keyless Entry System and TPMS (Receiver) 23AAE has 36 variations. For details of variations, see “Theory of Operation”. Hereinafter, Remote Keyless Entry System is called “RKES” in this report. 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 through ANT1 or ANT2 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 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.
