   NOTE:

   If the key is brought within 0.2 m (0.656 ft) of the rear bumper, communication is not possible.

   HINT: 

   • When the electrical key transmitter is brought near the outside electrical key oscillator, the possibility of wave interference decreases, and it can be determined if wave interference is causing the problem symptom.
   • If the operation 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

   Entry functions operate normally.

NG → See step   5 

OK → AFFECTED BY WAVE INTERFERENCE 

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

   1. Connect the Techstream to the DLC3.
   2. Turn the engine switch on (IG).
   3. Turn the Techstream on.
   4. Enter the following menus: Body Electrical / Smart Key / Utility / Communication Check (Key Diag Mode) / Overhead + Luggage (outside).
   5. When the electrical key transmitter is held at the same height as the rear bumper upper surface aligning it 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 exterior transmitter is operating normally.

      OK

      Wireless door lock buzzer sounds.

   E36-32 (CG8B) - Body ground	Always	10 kΩ or higher
   E36-31 (CLG8) - Body ground	Always	10 kΩ or higher

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

OK: Go to next step 

1. Replace the outside electrical key oscillator (luggage compartment). Refer to REMOVAL .

NEXT: Go to next step 

1. Check that the entry functions operate normally.

   OK

   Entry functions operate normally.

NG → See step   14 

OK → END (OUTSIDE ELECTRICAL KEY OSCILLATOR IS DEFECTIVE) 

1. Remove the luggage compartment door lock assembly. Refer to REMOVAL .
