I believe the flashing od light is to tell you there is a fault in the system, presumably the speedo cable as the speedo has stopped. The back up speed sensor is built into the speedo.

Hi had this fault years ago o/d light flashing because speedo not working.
If it's import auto like mine and it has a converter (km to mph) between gearbox and speedo
Cable this was the cause if so take converter out put speedo cable straight into gear box test drive if speedo works fault found
