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   19 

OK: Go to next step 

1. Remove the battery of the key. Refer to REPLACEMENT .
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 → See step   17 

OK: Go to next step 

1. Install the battery to the key. Refer to REPLACEMENT .
2. Bring the key near the indoor electrical key oscillator (for front floor), and check that the engine can be started.
   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 center floor), and check that the engine can be started.
   NOTE:

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

4. Bring the key near the indoor electrical key oscillator (for rear floor), and check that the engine can be started*.

   *: If the customize setting for Ignition Available Area is not set ALL, the engine will not start. Before performing this inspection, check that ALL has been selected. Refer to CUSTOMIZE PARAMETERS .

   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: 

   • 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 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
