Back Door Entry Unlock Function does not Operate [10/2013 - ]: Description

WARNING: This page is about a different variant/trim than selected.

If the entry back door open function does not operate but the back door entry lock function operates, the communication between the vehicle and key is normal. As a faulty part, the back door open switch circuit (from the back door opener switch assembly (opener switch) to the certification ECU (smart key ECU assembly) is suspected.
