A hardwire wake-up line monitoring and power saving method for a vehicle includes a secondary controller providing a wake-up signal to a supervisory controller via a hardwire wake-up line connected therebetween and the supervisory controller waking up in response to receiving the wake-up signal via the hardwire wake-up line, executing a set of functions for the secondary controller associated with the wake-up signal, detecting a malfunction of the hardwire wake-up line when the set of functions are completed or expired and the hardwire wake-up line is still providing the wake-up signal, and in response to detecting the malfunction of the hardwire wake-up line, transitioning to a low power mode where outputs of the supervisory controller are temporarily disabled to save power and the supervisory controller continues to monitor for a valid wake-up request.
