In general the wiring harnesses itself will never get a short or have a open within the harness unless its been in a fire or had mechanical damage done to the harness. Sometimes the harness may experience wire fatigue breakage when the harness is subjected to being constantly flexed back and forth.
The harness connectors sometimes fail due to mechanical damage or they become faulty because of corrosion and rust within the connector itself causing the contact pins to no longer carry a signal to the other modules.
So start by first inspecting the wiring harness and connectors for obvious damage or the connector just being loose. If the connectors and the harness passes the inspection then maybe you have a faulty computer module. But before even doing that make sure the battery and the charging system are good and supplying the proper voltages to the various modules.
