An exemplary system includes first and second controllers each configured to selectively operate in a master state and a standby state, a first watchdog timer associated with the first controller, and a second watchdog timer associated with the second controller. Each watchdog timer is configured to be either unexpired or expired. Selectively, the first controller operates in the master state and the second controller operates in the standby state when the first watchdog timer is unexpired and the second watchdog timer is expired, the first controller operates in the standby state and the second controller operates in the master state when the first watchdog timer is expired and the second watchdog timer is unexpired, and the first and second controllers both operate in the standby state when both the first and the second watchdog timer are expired or when both the first and the second watchdog timer are unexpired.
