Key Luggage Compartment Lock-In Prevention Function Does Not Operate: Procedure

1. Check that the entry luggage compartment open function operates. Refer to OPERATION CHECK [09/2012 - ] .

NG → See step   6 

OK: Go to next step 

1. Bring the electrical key transmitter near the indoor electrical key oscillator (for luggage compartment), and check that the entry luggage compartment lock-in prevention function operates.
   NOTE:

   If the key is brought within 0.2 m (0.656 ft.)of the indoor electrical key oscillator, communication is not possible.

   HINT: 

   • When the electrical key transmitter is brought near the indoor electrical key oscillator (for luggage compartment), the possibility of wave interference decreases, and it can be determined if wave interference is causing the problem symptom.
   • If the inspection result is that the operation check is normal, the possibility of wave interference is high. Also, added vehicle components may cause wave interference. If installed, remove them and perform the operation check.

OK → AFFECTED BY WAVE INTERFERENCE 

1. Diagnostic mode inspection indoor electrical key oscillator (for luggage compartment)

   1. Connect the Techstream to the DLC3.
   2. Turn the power switch ON (IG).
   3. Turn the Techstream on.
   4. Enter the following menus: Body Electrical / Smart Access / Smart Communication Check /Overhead + Luggage.
   5. When the electrical key transmitter is held at the same height as the rear bumper upper surface and aligned with the center of the rear of the vehicle, check that the wireless door lock buzzer sounds.

      HINT: 

      If the buzzer sounds, it can be determined that the luggage compartment interior transmitter is operating normally.

1. Disconnect the L15 ECU connector.
2. Disconnect the S44 oscillator connector.
3. Measure the resistance according to the value(s) in the table below.

   Standard resistance

   Tester Connection	Condition	Specified Condition
   L15-15 (CLG7) - S44-1 (CLG6)	Always	Below 1 Ω
   L15-16 (CG7B) - S44-3 (CLGB)	Always	Below 1 Ω
   S44-1 (CLG6) - Body ground	Always	10 kΩ or higher
   S44-3 (CLGB) - Body ground	Always	10 kΩ or higher

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

OK: Go to next step 

1. Replace the indoor electrical key oscillator with a new one or normally functioning one. Refer to REMOVAL [09/2012 - ] .
2. Check that the entry function operates normally. Refer to OPERATION CHECK [09/2012 - ] .

   OK

   Operates normally
