   *1	Approximately 0.3 m

   NOTE:

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

   HINT: 

   • When pressing the lock switch and touching the touch sensor, hold the electrical key transmitter about 1 m (3.28 ft.) above the ground and about 0.3 m (0.984 ft.) away from the vehicle as shown in the illustration.
   • When the key is brought near the front door outside handle assembly (for front passenger side), the possibility of wave interference decreases, and it can be determined if wave interference is causing the problem symptom.
   • If the operation 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   3 

OK → AFFECTED BY WAVE INTERFERENCE 

1. Disconnect the certification ECU (smart key ECU assembly) connector.
2. Disconnect the front door outside handle assembly (for front passenger side) connector.
3. Measure the resistance according to the value(s) in the table below.

   Standard Resistance

   Tester Connection	Condition	Specified Condition
   L62-5 (CLG2) - z4-6 (ANT1)	Always	Below 1 Ω
   L62-6 (CG2B) - z4-3 (ANT2)	Always	Below 1 Ω
   L62-33 (POS2) - z4-5 (B)	Always	Below 1 Ω
   L62-5 (CLG2) - Body ground	Always	10 kΩ or higher
   L62-6 (CG2B) - Body ground	Always	10 kΩ or higher
   L62-33 (POS2) - Body ground	Always	10 kΩ or higher
   z4-6 (ANT1) - Body ground	Always	10 kΩ or higher
   z4-3 (ANT2) - Body ground	Always	10 kΩ or higher
   z4-5 (B) - Body ground	Always	10 kΩ or higher

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

OK: Go to next step 

1. Measure the resistance according to the value(s) in the table below.

   Standard Resistance

   Tester Connection	Condition	Specified Condition
   z4-2 (GND) - Body ground	Always	Below 1 Ω

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

OK: Go to next step 

1. Reconnect the certification ECU (smart key ECU assembly) connector.
2. Measure the voltage and check for pulses according to the value(s) in the table below.

   Standard

   Tester Connection	Condition	Specified Condition
   z4-6 (ANT1) - z4-3 (ANT2)	Power switch off All doors closed Key not in cabin	No pulse generation
   z4-6 (ANT1) - z4-3 (ANT2)	Power switch off All doors closed Key not in cabin All doors locked by wireless lock function	Pulse generation
   z4-5 (B) - z4-2 (GND)	Power switch off	9 to 14 V
   z4-5 (B) - z4-2 (GND)	Power switch on (IG)	Below 2 V

NG → See step   9 

OK: Go to next step 

1. Replace the front door outside handle assembly (for front passenger side). Refer to DISASSEMBLY .

NEXT: Go to next step 

1. Check that the entry functions operate normally. Refer to OPERATION CHECK .

   OK

   Entry functions operate normally.

NG → See step   9 

OK → END (FRONT DOOR OUTSIDE HANDLE ASSEMBLY WAS DEFECTIVE)
