(1) First display. (2) Second display. (3) Module identifier (MID). (4) Service code indicator "SERV CODE". (5) Component identifier (CID). (6) Failure mode identifier (FMI).Scrolling mode allows service personnel or an operator to see diagnostic codes that were stored by the main display module. The diagnostic code in this mode can not be cleared. The diagnostic code can also not be placed on hold. The diagnostic codes momentarily scroll on the display area upon entering the scrolling mode. The MID is shown first as each diagnostic code is shown for about one second. The corresponding CID and the corresponding FMI is shown second for about two seconds. "End" appears when the last diagnostic code has been shown. The diagnostic codes are then shown. The display shows "- - -" when the main display module has no diagnostic codes. The "SERV CODE" functions as a diagnostic present indicator in scrolling mode. The diagnostic that has caused a diagnostic code to be shown currently is present when "SERV CODE" is ON. "SERV CODE" is OFF when the fault is not present, but the fault has previously occurred.
