Abstract
A control and diagnosis methodology for an electronic module of a vehicle is presented here. In accordance with the disclosed method, at least one wake up event for a processor of the electronic module is performed during an inactive shutdown state of the vehicle. The at least one wake up event is initiated by a wake up timer of the electronic module. The method continues by logging, during the inactive shutdown state of the vehicle, wake up information associated with the at least one wake up event to obtain logged wake up information. The logged wake up information is analyzed during an active operating state of the vehicle to obtain a wake up diagnosis, and the method generates, during the active operating state of the vehicle, an output indicative of the wake up diagnosis.
