Codes above P0800 series are considered manufacturer specific. So each manufacturer can make up their own definitions. Without year, make, model, engine, no one can answer your question.

Codes greater than P0800 are always MANUFACTERER specific code, which means we would need the year, make, model, and engine to decipher that for you.

What kool king? Some are fully evaporative, some partial. None the less depending on humidity and how much condensation machine is producing all need drained. Typically it will shut down when and if it needs drained but if you are concerned, pull the plug!!

You've got trouble codes stored by they're most likely enhanced codes that your code reader can't read. Inexpensive code readers and only read generic trouble codes. Codes above P0800 are "enhanced" code that require a more professional scan tool to access.

The tank on your Road King is on the bottom of the transmission. Look underneath the transmission and you'll see two drain plugs. The plug on left front of the oil pan is the engine oil drain. The plug near the center of the pan is the transmission drain plug. Good Luck, Steve
