Luggage Compartment Door Entry Unlock Function does not Operate when Key is Outside Luggage Compartment [09/2014 - 10/2015]: Description

If the luggage compartment door entry unlock function does not operate, the request code may not be being transmitted from the luggage compartment door. If the entry functions for other doors operate properly, communication between the electrical key transmitter sub-assembly and door control receiver 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]), a luggage compartment door outer switch malfunction or wave interference.

HINT:

If the luggage compartment door open functions does not operate, the cause of the malfunction may be stored in the certification ECU (smart key ECU assembly) (Refer to OPERATION HISTORY LIST [09/2014 - ] ).
If the cause of the malfunction is stored in the certification ECU (smart key ECU assembly), the following table is helpful in checking whether or not the malfunction was caused by wave interference.

RADIO WAVE INTERFERENCE:

Parameter Name	Cause of Problem and Countermeasure
Operating Trunk Switch / Key RF Signal Interference	When entry trunk operation was performed, the electrical key transmitter sub-assembly could not be confirmed due to wave interference. Therefore, the output frequency was switched to the other channel (changed from channel 1 to channel 2 or from channel 2 to channel 1). If the cause of the malfunction has not been stored but the car has been moved and a luggage compartment door open function has been successfully performed, the possibility of wave interference is high.
