The error code 173 in a Chevrolet vehicle typically indicates an internal error in the communication to, or the functionality of the rear differential control module. This is extremely important, as the RDCM is responsible for managing and transmitting signals to the cars wheels. If Youre seeing an error code appear and there is no worrying noise or smoke coming from the vehicle, Youre most likely experiencing a software or firmware issue. This means Youll need to update the firmware on Your car, or see if some other factor is causing this malfunction. Its best to take Your car to an expert to get this done. The dealership where You purchased Your car, or any auto-shop in Your locality should be able to rectify the software issue for You.
