Zusammenfassung:A control device for an in-vehicle unit installed in a vehicle having a warning light includes a control circuit and a storage circuit. The control circuit executes an abnormality detection process, a detection result write-in process, and a lighting request output process. The storage circuit retains contents of the history information even when the in-vehicle unit is powered on or powered off. The control circuit is configured to retrieve the contents of the history information from the storage circuit when the in-vehicle unit is powered on. When the detection history is written in the retrieved contents, the control circuit outputs the lighting request even when an abnormality of the in-vehicle unit cannot be detected by the abnormality detection process.
