Many of the Sea-Doo display units need to be Flashed with software prior to installing and marrying the display to the ECU.Specifically, the 278002270 LCD Display unit needs to be "Flashed" to the appropriate flash code that matches the SeaDoo ECU. This needs to be done by a BRP / SEA-DOO Dealer. Neither the CanDooPro or SBT's Scan Tool is capable of putting this flash code into the LCD Guage. The CanDooPro and the Scantool are capable of "Marrying" the LCD Guage to the ECU after it has been "Flashed".
