If you are sure of accessories like fiber optic cable and SYNC Module,In such case I test the CPU individually.When a CPU intermittently report that an intact SYNC Module is not available and then available several times, perhaps some thing is wrong with mechanical or electronics parts inside CPU that keep and detect the existence of SYNC Module.In this case, I suggest consulting with people HERE (Support Request).
