DESCRIPTION
When the wireless operation can be used to lock and unlock the doors, communication between the electrical key and TPMS receiver assembly and certification ECU (smart key ECU assembly) is normal. If the entry lock and unlock functions do not operate, the entry cancel function may be set through the customize function, there may be communication problems between the electrical key transmitter sub-assembly and vehicle, or there may be wave interference.
