My name is ***** ***** I am a professional here at Just Answer. I noticed that your question had not received a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.
The first thing you need to do here is check and make sure the battery cables are connected properly.If an issue is found with the cables being connected incorrectly this fault here can occur.If you cannot access the battery any more due to the trunk being locked out see if you have a metal key blade to use in the trunk lock cylinder to see if the trunk will release then.If not a lock smith may have to come out and release the trunk so you can access the battery.If the battery is connected properly once you do access it I would have the battery tested to see if it is faulty/shorted internally needing replaced.If these are all o.k. let me know.
