Inspection Procedure

1. Check that the entry lock and unlock function can be operated at each door (see OPERATION CHECK  )

   OK: entry functions operate normally. 

NG: GO TO DTC OF OTHER COMPONENTS (PROCEED TO PROBLEM SYMPTOM FLOWCHART FOR EACH DOOR)  (See PROBLEM SYMPTOMS TABLE  )

OK: Go to next Step 

1. When the luggage compartment door opener switch is operated, check that the luggage compartment door opens (see OPERATION CHECK ).

   OK: Luggage compartment door opens. 

NG: GO TO POWER TRUNK LID SYSTEM  (See PROBLEM SYMPTOMS TABLE )

OK: Go to next Step 

1. Using the intelligent tester or Techstream, read the Data List (see DATA LIST / ACTIVE TEST  )
   1. Intelligent tester

      OK: On tester screen, item changes between ON and OFF according to above chart. 

NG:  Go to step  9

OK: Go to next Step 

1. Bring the electrical key transmitter near the electrical key antenna (in rear bumper), and perform an entry luggage compartment open function check
   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 electrical key antenna, 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: Entry functions operate normally. 

NG: Go to step 5 

OK: AFFECTED BY WAVE INTERFERENCE 

1. Diagnostic mode inspection (electrical key antenna)
   1. Connect the intelligent tester or Techstream to the DLC3.
   2. Turn the power switch ON (IG)
   3. Turn the tester on
   4. Enter the following menus
      1. Intelligent tester - Select: DIAGNOSIS / OBD/ MOBD / SMART ACCESS / ID UTILITY / SMART DIAGMODE / LUGG + OVERHEAD
      2. Techstream - Select. 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 exterior transmitter is operating normally

      OK: Wireless door lock buzzer sounds 

NG: Go to step 6 

OK: REPLACE CERTIFICATION ECU  (See REMOVAL )

1. Disconnect the L15 ECU connector
2. Disconnect the R40 antenna connector.
3. Measure the resistance according to the value (s) in the table below

   Standard resistance 

   TESTER CONNECTION SPECIFIED CONDITION CHART
   
   

   Tester Connection	Condition	Specified Condition
   L15-31 (CLG8) - R40-1 (CLG5)	Always	Below 1 Ω
   L15-32 (CG8B) - R40-2 (CLGB)	Always	Below 1 Ω
   L15-31 (CLG8) - Body ground	Always	10 kΩ or higher
   L15-32 (CG8B) - Body ground	Always	10 kΩ or higher

NG: REPAIR OR REPLACE HARNESS OR CONNECTOR 

OK: Go to next Step 

1. Replace the electrical key antenna with a new or normally functioning one (see REMOVAL  )
2. Check that the entry luggage compartment open function operates normally (see OPERATION CHECK  )

   OK: Operates normally 

NG: Go to step 8 

OK: END (ELECTRICAL KEY ANTENNA IS DEFECTIVE) 

1. Replace the luggage closer motor with a new or normally functioning one (see REMOVAL )
2. Check that the entry luggage compartment open function operates normally (see OPERATION CHECK  ).

   OK: Operates normally 

NG: REPLACE CERTIFICATION ECU  (See REMOVAL )

OK: END (LUGGAGE CLOSER MOTOR IS DEFECTIVE) 

1. Measure the resistance according to the value (s) in the table below

   Standard resistance
