DDEC IV DIAGNOSTIC CODES

To Read Codes:
Plug a diagnostic data reader into the receptacle located on the side panel of the L.H. control panel or
momentarily depress the STOP ENGINE OVERRIDE switch, located on the L.H. lower control panel, with
the ignition ON, the engine idling or engine shut-off. Active codes will be flashed on the STOP ENGINE
indicator light, located on the central dashboard, followed by the inactive codes being flashed on the CHECK
ENGINE indicator light located on the central dashboard. The cycle is repeated until the operator depresses
the STOP ENGINE OVERRIDE switch. For example; a code "43" consists of four flashes, followed by a
short pause, then another three flashes in quick succession. The following table is a list of the diagnostic
codes.
