Ok your problem maybe software related, to solve this, u will need to take both battery terminals off, then take both & touch them together for a few like 10 seconds, what that is going to do is to reset all the vehicles control module that have a issue, note will not arm the vehicle in anyways what so ever, now refit both & reset your time & date & u should be good, if that works let me know, if not get the codes read from the system & post it here, good luck.
