04 System Communication 18-60 TPMS Control Unit Tire Pressure Sensor • When the vehicle is traveling more than 45 km/h (28 mph), an RF (radio frequency) band wave signal is transmitted from each tire pressure sensor to the control unit. • When the wheels rotate, and the tire pressure sensors momentum is detected, switching them from sleep mode to normal function (awake) mode. After the vehicle is stationary for 5 minutes, the sensors switch from normal • Each tire pressure sensor has its own ID to prevent jamming by similar systems on other vehicles. After memorizing all the sensor IDs, the control unit recognizes only those specific signals. • An ID cannot be memorized automatically. The control unit knows which ID belongs to each tire pressure sensor. This recurring ID confirmation prevents any confusion in the system as a result of normal tire rotation. NOTE: Be careful not to bend the brackets on the TPMS control unit: Misalignment of the control unit could interfere 08/08/21 14:58:25 61SNR030_180_0060 |
