1999 Ford Econoline Super Duty Custom 7.3L MIL Lamp on VIN: 1FDXE47FXX
P0603: PCM Keep Alive Memory Test Error. Hi, I've got this one throwing this code as soon as you start it. I tried looking in my 'new' worthless AllData and can't find any diagnostic info on this. Is it something simple? Customer is waiting... Thanks, Dan
