We have noticed that an updated maxisys will not communicate with several models and makes of vehicles and this is one of them. We have a ten year old diagnostic computer that will. Doesn't make any sense. Especially after an $800.00 update. We need the maxisys to do it's job so we can do ours. The older system would get into a 2014 nissan and diagnose and clear codes and maxisys would not. Please help. Thanks
