   *a	Approximately 0.3 m (0.984 ft.)

   NOTE:

   If the electrical key transmitter sub-assembly is brought within 0.2 m (0.656 ft.) of the rear bumper, communication may not be possible.

   HINT: 

   • When pressing the luggage door opening switch assembly, hold the electrical key transmitter sub-assembly approximately 1 m (3.28 ft.) above the ground and approximately 0.3 m (0.984 ft.) away from the vehicle as shown in the illustration.
   • When the electrical key transmitter sub-assembly is brought near the electrical key antenna (outside luggage), the possibility of wave interference decreases, and it can be determined if wave interference is causing the problem symptom.
   • If the operation check 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

   Entry functions operate normally.

NG → See step   5 

OK → AFFECTED BY WAVE INTERFERENCE 

1. Check the following antenna in key diagnostic mode. Refer to OPERATION CHECK [08/2014 - ] .
2. Select either channel 1 or channel 2 and inspect key diagnostic mode for each channel.

   *a	0.7 to 1.0 m (2.30 to 3.28 ft.)

   1. When the electrical key transmitter sub-assembly is held at the same height as the rear bumper upper surface, align it with the center of the rear of the vehicle and check that the wireless door lock buzzer sounds.

      HINT: 

      • Hold the electrical key transmitter sub-assembly at the same height as the rear bumper upper surface and align it with the center of the rear of the vehicle (0.7 to 1.0 m (2.30 to 3.28 ft.)). Make sure that the direction of the electrical key transmitter sub-assembly is as shown in the illustration.
      • If the buzzer sounds, it can be determined that the electrical key antenna (outside luggage) is operating normally.
      • If the buzzer sounds with [CH1] displayed but not with [CH2], the electrical key transmitter sub-assembly cannot be detected by channel 2 due to a malfunction, such as wave interference.

      OK

      Wireless door lock buzzer sounds.

NG → See step   6 

OK → See step   11 

1. Disconnect the Q1 certification ECU (smart key ECU assembly) connector.
2. Disconnect the U10 electrical key antenna (outside luggage) connector.
3. Measure the resistance according to the value(s) in the table below.

   Tester Connection	Condition	Specified Condition
   Q1-1 (CG8B) - U10-2 (CLGB)	Always	Below 1 Ω
   Q1-2 (CLG8) - U10-1 (ANTE8)	Always	Below 1 Ω
   Q1-1 (CG8B) or U10-2 (CLGB) - Body ground	Always	10 kΩ or higher
   Q1-2 (CLG8) or U10-1 (ANTE8) - Body ground	Always	10 kΩ or higher

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

OK: Go to next step 

1. Remove the electrical key antenna (outside luggage). Refer to REMOVAL [08/2014 - ] .
