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.
