Abstract

Systems and methods for determining a fault in an electronic controller. The system includes a first electronic controller, a second electronic controller, and a remote electronic controller. The second electronic controller executes a diagnostic service routine configured to access a restricted section of a memory associated with the first electronic controller, receives a failure code from the restricted section of the memory associated with the first electronic controller, generates a logging file including the failure code, and sends the logging file to the remote electronic controller. The remote electronic controller determines a fault in the first electronic controller based upon the logging file.
