An engine electronic control unit (ECU) for a vehicle includes a non-volatile memory and a microcontroller. The non-volatile memory is configured to store an indicator of ignition status having an initial off-status. The microcontroller is coupled to the non-volatile memory and is configured to receive a SOC of a battery for the engine ECU. The microcontroller is further configured to determine the SOC is insufficient to power-up the engine ECU following a reset condition. The microcontroller is further configured to disable over-writing the indicator of ignition status in response to determining the SOC is insufficient.
