1. A display control device that is configured to acquire update data from outside and distribute the acquired update data to a rewrite target electronic control unit (ECU), the device comprising:
a cancellation detection unit that is configured to detect a cancellation regarding a program rewrite from first update data stored in a second data storage bank of the rewrite target ECU to second update data acquired from an external device, the program rewrite being performed when a first data storage bank of the rewrite target ECU serves as an active bank;
a write instruction unit that is configured to distribute the second update data to the rewrite target ECU and instruct the rewrite target ECU to write the second update data thereinto; and
a notification instruction unit that is configured to give an instruction for notification of a progress regarding the program rewrite, wherein
the notification instruction unit is further configured to:
give the instruction to make the notification of the progress regarding the program rewrite in a first manner when the write instruction unit is distributing the second update data; and
give the instruction to make the notification of the progress regarding the program rewrite in a second manner when the cancellation detection unit detects the cancellation, and

the write instruction unit is further configured to continue distributing the second update data when the cancellation detection unit detects the cancellation during distribution of the second update data by the rewrite instruction unit.
