System and method for control module alarm wake

A system for a vehicle, comprising:

• an engine system, including an engine configured to propel the vehicle by combusting air and fuel;
• a fuel system, including a fuel tank for storing the fuel;
• an evaporative emissions system in fluidic communication with the fuel system and an intake of the engine;
• a control system, including a plurality of control modules communicatively coupled over a controller area network;
• and
• a first control module of the plurality of control modules, the first control module including an alarm wake system and storing instructions in non-transitory memory that, when executed, cause the first control module to:
• during a shutdown event,
• schedule an alarm wake up via the alarm wake system prior to transitioning to a sleep mode when an alarm wake up count is less than a threshold count;
• and
• transition to the sleep mode without scheduling the alarm wake up when the alarm wake up count is equal to the threshold count.
