ABSTRACT:
The disclosed embodiments may relate to vehicle (10) having a control system (12) located within the vehicle (10). The control system (12) may include a processor (26) and a wake-up circuit (46) coupled to the processor (26). The processor (26) may utilize a program (34) during a standby mode of operation. The program (34) is configured to provide a voltage to the wake-up circuit (46) for a first time period (T1) once an interrupt is received by the processor (26). Then, the program (34) may monitor the wake-up circuit (46) for a second time period (T2). If a response of the wake-up circuit (46) exceeds at least one of a plurality of predetermined limits, then the program (34) may recalibrate the wake-up circuit (46).
