    See step  3

  3. CHECK SMART KEY SYSTEM OPERATION (FOR CHARGING PORT LID) 
    1. Close all of the doors.
    2. Lock all of the doors.
    3. Hold the electrical key transmitter sub-assembly at the same height as the charging port lid and approximately 0.7 to 1 m (2.30 to 3.28 ft.) from the vehicle as shown in the illustration and check that the LED of the electrical key transmitter sub-assembly blinks.

      HINT: 

      • The charging port lid is located on the rear right side of the vehicle.
      • Make sure to perform this inspection with all of the doors locked. (The entry function and charging port lid verification function cannot be operated if any of the doors are unlocked.)

      *1 Charging Port Lid
      *a 0.7 to 1 m (2.30 to 3.28 ft.)
    4. Hold the electrical key transmitter sub-assembly at the same height as the No. 2 electrical key antenna (extra antenna) and approximately 0.3 m (0.983 ft.) from the vehicle as shown in the illustration and check that the LED of the electrical key transmitter sub-assembly blinks.

      HINT: 

      • The charging port lid control receiver (No. 2 electrical key antenna) is located on the rear right side of the vehicle under the charging port lid.
      • When the electrical key transmitter sub-assembly is brought near the charging port lid control receiver (No. 2 electrical key antenna), the possibility of wave interference decreases, and it can be determined if wave interference is causing the problem symptom.
      • If the inspection result is that the problem only occurs in certain locations or at certain 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.
      • There may be wave interference if the vehicle is near broadcasting antennas, large video displays, wireless garage door opener systems, wireless security cameras, home security systems, etc. In this case, move the vehicle to a different location and check if there is any improvement.
      • Communication may not be possible if the electrical key transmitter sub-assembly is within 0.2 m (0.656 ft.) of the charging port lid.
