Hello and welcome to JustAnswer!

This code sets when the engine controller loses communication with the dosing control unit. The dosing control unit is the module that takes care of exhaust fluid functions. This could be the module itself, a loss of power or ground to it or a bus communication circuit issue between the two.

Has any actual testing been done?
