All Door Entry Lock/Unlock Functions and Wireless Functions do not Operate [09/2014 - ]: Description

When the entry operation and wireless operation of the door lock functions do not operate, a malfunction or wave interference may be occurring in either of the following: 1) the signal communication line between the door control receiver and certification ECU (smart key ECU assembly) (the line used for entry and wireless operations); or 2) the electrical key transmitter sub-assembly. If the entry lock and wireless lock operations cannot be performed, there may be electrical key transmitter sub-assembly malfunctions, wave interference or problems in the communication which is used for the entry and wireless function between the door control receiver and certification ECU (smart key ECU assembly).
