1. Turn the power switch off.
2. Open and close the front passenger door.
3. Hold the electrical key transmitter sub-assembly at the same height as the door outside handle assembly and approximately 0.3 m (0.984 ft.) from the front passenger door.
4. Read the Data List according to the display on the Techstream.
5. Touch the lock sensor of the front door outside handle assembly (for front passenger door).

   HINT: 

   • If the door does not lock even when touching the lock sensor, touch it with your palm.
   • When checking the operation of the lock sensor again, make sure to perform the procedure from step (a).

   HINT: 

   When checking the operation of the entry lock function several times, it can be operated up to 2 times consecutively. To operate the function 3 times or more consecutively, the doors need to be unlocked once. However, this is only for the entry lock function, other door lock operations, such as a wireless door lock operation can be performed consecutively.

   OK

   The Techstream display changes correctly in response to the operation of the front door outside handle assembly (for front passenger door).
