Polaris Fault Codes

Can anyone tell me if Polaris used the same fault codes for all bikes for all years or have they changed over time?

I'm trying to find a list of fault codes for a 2003 Sportsman 500 H.O.

the codes used are different between the single cylinder and twin's because they use different EFI systems.

The single's use the Visteon system while the twins use a Bosch system.
