Abstract
A tire condition sensor module (14) for a vehicle (10) comprises at least one actuatable tire condition sensor (78, 84, 88) for sensing a tire condition of an associated vehicle tire (20) and a motion detector (32) for detecting movement of the associated vehicle tire (20). The module (14) further includes a transmitter (44) for transmitting a tire condition indicating signal having a characteristic based on the sensed tire condition signal. A controller (74) controls actuation of the tire condition sensor (78, 84, 88) and the transmitter (44). The controller (74) is continuously energized and has first and second operating modes. The controller (74) operates in the first operating mode when movement of the associated tire (20) is greater than a predetermined value and operates in the second operating mode when movement of the associated tire (20) is less than the predetermined value.
