Claim Text:
1. A method for locking a control device to be wakened by a wake up signal, the method comprising: applying a voltage to a bistable element; detecting a temperature of the control device by a temperature-sensitive component; wherein if, during an initial start, the temperature of the control device is lower than a critical temperature, switching the bistable element to block a transistor so that the wake-up signal is not shunted by the transistor from the signal path to ground and thereby allow waking of the control device by the wake-up signal transmitted via the signal path, and wherein if, during a fault, the temperature of the control device is above the critical temperature, switching the bistable element so that the transistor is conductive, so that the wake-up signal is shunted by the transistor from the signal path to ground to block the wake-up signal.
