FCC ID:OUCG8D-369KA G8D-369KA Receiver, Tire Pressure Monitoring System
FCC ID:OUCG8D-369KA - 2 - - 1. Constitution of the Tire Pressure Monitoring System for vehicle Tire Pressure Monitoring System is the system that receives the information, from transmitters installed at each tire, about the inflation pressure or temperature of tires detected by the sensor, so that the system can detect the abnormality of tires like fallen inflation pressure. This system consists of transmitter, receiving antenna, and receiver. The transmitter sends information of tire, read by the sensor, in the form of radio wave at constant intervals. The receiver is fixed inside the vehicle. If IG is OFF, it works intermittently to prevent the battery exhaustion. When the receiver detects the synchronous code and IG is ON, it runs continuously to receive the signals completely. If the received code is normal, the system will not inform the user. As shown below, in the case that the transmitter sends information that the tire is in abnormal condition, and that the receiver system has a trouble, the system will inform the user with lighting up Warning bulb. TPMS Warning bulb is lit by the following situations. Bulb disconnection detection output（The warning light is On for 3 sec. when IG=OFF→ON） Tire air pressure warning output (Warning light is ON) System warning output (Warning light is blinking) Pressure sensor 1 CPU Receiving circuit CPU Bulb EEPROM Transmission Transmitter 1 Receiver Inside Antenna Transmitter 2 Transmitter 3 Transmitter 4 Figure 2-1 System Architecture Tire
FCC ID:OUCG8D-369KA - 3 - - 2. User’s manual (provisionally) Tire inflation pressure warning light This light illuminates if the inflation pressure of any tire (except for compact spare tire) drops while the ignition key is in the “ON” position. It normally illuminates when the ignition key is turned to the “ON” position and goes off a few seconds later. If the warning light illuminates while driving Avoiding hard braking, hard steering, and high speeds, drive to the nearest gas station or authorize car dealer and adjust the tire inflation pressures.(except for compact spare tire) If the warning light blinking while driving It is thought abnormality of the device, go to the check to the nearest car dealer as soon as possible. Whenever the tires and wheels are replaced with new ones Tire inflation pressure sensors must be fitted on the new wheels and their ID codes must be programmed into the system. Have tire and wheel replacement performed by an authorized car dealer to avoid the risk of damaging the tire inflation pressure sensors. ＣＡＵＴＩＯＮ ・ If the tire inflation pressure warning-light does not illuminate when the ignition key is turned to the “ON” position the system may be faulty. ・ If the tire inflation pressure warning light illuminates while you are driving, avoid hard braking, hard steering, and high speeds. Otherwise, you could make the vehicle unstable and have a serious accident. ・ The tire inflation pressure warning light may not illuminate immediately in the event of a tire blowout or rapid leak..
