    1484.03 Is limit switch, clutch pedal, voltage above normal 0669.02 speed sensor (transmission input) incorrect signal 274.03 Atmospheric pressure sensor, voltage above normal 549.02 incorrect throttle lock switch inputs (could be throttle lock mode switch or throttle speed set switch) hope this helps

    It's the engine ECM. If you want a complete Electrical Schematic then post your machine Serial Number.
