All Door Entry Lock/Unlock Functions do not Operate, but Wireless Functions Operate [08/2013 - ]: Description

When the wireless operation can be used to lock and unlock the doors, the communication line between the door control receiver and certification ECU (smart key ECU assembly) is normal. When the entry operation does not operate, one of the following may be the cause: 1) entry cancel function is set through customization; 2) malfunction in smart access system with push-button start communication line (electrical key transmitter and vehicle); or 3) wave interference.
