Abstract: A vehicle disablement device disables a vehicle if it a payment has not been received prior to a payment due deadline. The vehicle can also be disabled if it is determined that the vehicle disablement device is being tampered with. Disablement of the vehicle occurs by transmission of a wireless signal from a vehicle disablement device to a relay in a power control panel. The disablement can also occur by transmission of a second wireless signal from a tamper disabler (or a tamper receiver) to a relay in the power control panel. The critical system of the vehicle that can be disabled by the vehicle disablement device can be the same or a different critical system as that which can be disabled by the tamper disabler (or a tamper receiver).
