Room Oscillator does not Recognize Key: Procedure

1. Check that entry lock and unlock functions can be operated at each door. Refer to OPERATION CHECK .

   OK

   Entry lock and unlock functions operate normally.

NG → See step   11 

OK: Go to next step 

1. Remove the battery of the key. Refer to REMOVAL .

2. With the brake pedal depressed, touch the engine switch while facing the logo side of the key to the engine switch.
3. When operating the engine switch, check whether the power source mode changes.

   OK

   Power source mode changes.

   HINT: 

   • When the key cannot be verified even though it is within the specified range, the engine start check can be performed by removing the transmitter battery from the key and holding the transmitter close to the engine switch.
   • When performing the check, if the power source mode changes, there is a problem with key certification inside the cabin.

NG → GO TO SMART ACCESS SYSTEM WITH PUSH-BUTTON START (for Start Function) (Proceed to Power Source Mode does not Change) 

OK: Go to next step 

1. Install the battery to the key. Refer to INSTALLATION .
2. Bring the key near the indoor electrical key oscillator (for front floor), and perform an engine start check.
   NOTE:

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

3. Bring the key near the indoor electrical key oscillator (for rear floor), and perform an engine start check*.
   NOTE:

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

   HINT: 

   • *: If the customize setting for Ignition Available Area is not set All, the hybrid vehicle control system will not start. Before performing this inspection, check that All has been selected. Refer to CUSTOMIZE PARAMETERS .
   • When the key is brought near the indoor 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 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

   The engine starts.

NG → See step   4 

OK → AFFECTED BY WAVE INTERFERENCE 

1. Diagnostic mode inspection (indoor electrical key oscillator (for front floor))

   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 Access / Utility / Communication Check (Key Diag Mode) / Overhead + Front Room.
   5. When the key is placed on the driver seat or front passenger seat cushion, check that the wireless door lock buzzer sounds.

      HINT: 

      Place the key on the driver or front passenger seat cushion.

2. Diagnostic mode inspection (indoor electrical key oscillator (for rear floor))

   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 Access / Utility / Communication Check (Key Diag Mode) / Overhead + Rear Room.
   5. When the key is placed on the rear seat cushion, check that the wireless door lock buzzer sounds.

      HINT: 

      • Place the key on the rear seat cushion.
      • If the buzzer sounds, it can be determined that the indoor electrical key oscillators are operating normally.
      RESULT
      
      

      Result	Proceed to
      Wireless door lock buzzer does not sound only for indoor electrical key oscillator (for front floor).	A
      Wireless door lock buzzer does not sound only for indoor electrical key oscillator (for rear floor).	B
      Wireless door lock buzzer sounds for all indoor electrical key oscillators.	C
