This trucks display is the access 1 module. If it does beep that means the access 1 is getting power and recognizes the truck has keyed on. If the display is blank, either there is a software mismatch between all the modules, or there is an internal issue within the access 1 module.
You can test your k1 relay in the distribution board to ensure it is getting full voltage.
With no codes in the history, it leads me to believe your access 1 module has an issue and needs to be replaced.
