   SMART ACCESS
   
   

   Tester Display	Measurement Item/Range	Normal Condition	Diagnostic Note
   Dr-Door Trigger Switch	Rear door LH touch sensor (lock sensor) / ON or OFF	ON: Rear door LH touch sensor (lock sensor) touched OFF: Rear door LH touch sensor (lock sensor) not touched	Displays whether the lock sensor is on or off (even if the sensor is touched and contact is maintained, "ON" is displayed only momentarily). Use this Data List item to help determine if there is a lock sensor malfunction when the entry lock function does not operate.

   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 rear door outside handle assembly LH.
