Abstract
A fuel system diagnostic wakeup system for a vehicle includes a first control module. The first control module generates a wakeup request, powers off when the vehicle powers off, and powers on and performs a fuel system diagnostic in response to a wakeup signal while the vehicle is powered off. A second control module independent of the first control module receives the wakeup request and generates the wakeup signal after the vehicle powers off based on the wakeup request.
