Re: 2003 Ford Excursion 6.0 Powerstroke No start code P2285
If you've done any work to the HPO system, you're going to have air in the lines and will get the 2285 code. The 1000 code has something to do with a drive cycle. Basically, the computer must see all parameters within spec for a certain amount of time before it will clear. The 603 is just keep alive memory which usually comes about when disconnecting batteries or when you have bad voltage.
