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 / Data List.
5. Read the Data List according to the display on the Techstream.

B: Go to next step 

1. Move the electrical key transmitter as described below and perform the operation inspection.

   HINT: 

   • When the electrical key transmitter is brought near the door outside handle assembly or electrical key antenna, the possibility of wave interference decreases, and it can be determined if wave interference is causing the problem symptom.
   • The transmitting waves of the wireless functions and entry functions are the same, but the wave logic is different. Therefore, it is possible that only the wireless functions or only the entry functions are affected by wave interference.
2. Bring the electrical key transmitter near the driver door outside handle assembly, and perform a front driver door entry lock and unlock operation check.

   NOTE:

   If the key is brought within 0.2 m (0.656 ft.) of the door outside handle assembly, communication is not possible.

3. Bring the electrical key transmitter near the front passenger door outside handle assembly, and perform a front passenger door entry lock and unlock operation check.

   NOTE:

   If the key is brought within 0.2 m (0.656 ft.) of the door outside handle assembly, communication is not possible.

4. Bring the electrical key transmitter near the outside electrical key oscillator (luggage compartment), and perform an entry luggage compartment door 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: 

   If the inspection result is that the problem only occurs in certain locations or times of day, the possibility of wave interference is high. Also, added vehicle components may cause wave interference. If installed, remove them and perform the operation check.

   Result	Proceed to
   Some operation checks are normal	A
   All operation checks fail	B

A → AFFECTED BY WAVE INTERFERENCE
