Abstract: A method of operating an entry system of a motor vehicle includes monitoring a battery voltage and the entry system continuously using a control circuit of the latch assembly in a non-emergency mode. Power is provided to the control circuit in the event of a loss of power from a main power source using a backup energy source of the control circuit. The method includes transitioning to an emergency mode in response to determining loss of power from the main power source or failure of the component of the entry system. An actuation group associated with the latch assembly is operated with the control circuit using power from the backup energy source of the control circuit in response to determining that actuation from a plurality of pins of a mechanical emergency switch assembly indicates a command from a user to unlatch the closure member in the emergency mode.
