Abstract
A signal receiver for tire air pressure monitoring system determines whether the pressure detection signals from all transmitters have been received during an engine stop state. Upon affirmative determination, the receiver sets a timer, and deactivates the entire or partial function of the receiver. The receiver determines whether the second predetermined period has expired after the setting of the timer. Until the period passes, the receiver retains the deactivated state thereby to save electric power consumption during engine stop state.
