Hello and welcome to JustAnswer!

U0073 is for a communication bus issue. This code will set in a module when it isn't able to establish bus communication with other modules.

The modules all communicate with each other over a wired network. If there is an open circuit, a short to power or ground in the wiring, an internal failure in a module shorting the network to power or ground, or an internal failure in the module setting the code then it will prevent communication.
