U0469Invalid Data Received From Starter / Generator Control Module

U0469 is a communication fault indicating that one or more control modules received invalid or missing data from the starter/generator control module over the vehicle's network. The computer detected a problem with the quality or timing of the serial data messages coming from that module, not necessarily a failure of the starter or generator itself.
