Back Door Entry Lock and Unlock Functions do not Operate [02/2014 - 11/2016]: Description

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

If the entry lock and unlock functions do not operate for the back door only, the request code may not be being transmitted from the back door. If the entry functions for other doors operate properly, communication between the electrical key transmitter sub-assembly and electrical key and tire pressure monitoring system receiver assembly is normal. In this case, there may be a problem with request code transmission (communication between the certification ECU (smart key ECU assembly) and electrical key antenna (outside luggage compartment)), or there may be electric wave interference.
