I'm going to assume that only applies if I have been an Onstar subscriber full time (which I have not). Was wondering if that information is stored for the life of the vehicle in the ECU, and can be retrieved?copperbeech said:I am not sure re your Q but as a somewhat related comment, Onstar's monthly report includes a statement showing a reset on the OLM. HOWEVER on at least one occasion it failed to pick it up ie I reset and it didnt "see it" ???.
