Wait to start light won't go off
 

Hi everyone I'm new to diesel bombers and just bought my first diesel about a month ago and have had a problem here lately and wanted to see if anyone else has the same problem. My wait to start light came on after installing a hypertech max energy tuner. Never had any trouble before hand just after the truck is stock other than the tuner I have removed it set it back to stock and even removed the battery cables to try to eleminate a phantom code but it still comes back. Only shows up when it gets warm highway speeds or city driving it doesnt matter no loss of power just the annoying light and code p1223 any tips would be appreciated thank you for your time and sorry the discription is so long.:argh:
