Front Passenger Side Door Entry Lock and Unlock Functions do not Operate [12/2012 - ]: Procedure

1. When the door control switch on the multiplex network master switch assembly is operated, check that the doors unlock and lock according to the switch operation.

   Refer to OPERATION CHECK [12/2012 - ]

   Result	Proceed to
   	Door locks operate normally
   	Door locks do not operate

Result: 

Door locks do not operate 

GO TO POWER DOOR LOCK CONTROL SYSTEM. Refer to  HOW TO PROCEED WITH TROUBLESHOOTING [12/2012 - ] 

Result: 

Door locks operate normally 

See step  2

1. Bring the electrical key transmitter sub-assembly approximately 0.3 m (0.984 ft.) from the front door outside handle assembly (for front passenger door) and perform an entry function check.

   Refer to OPERATION CHECK [12/2012 - 08/2016] or OPERATION CHECK [08/2016 - ] .

   *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 door handle, communication may not be possible.

   HINT: 

   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.

   Result	Proceed to
   	Entry function does not operate normally
   	Entry function operates normally

Result: 

Entry function operates normally 

AFFECTED BY WAVE INTERFERENCE 

Result: 

Entry function does not operate normally 

See step  3

1. Disconnect the I7 front door outside handle assembly (for front passenger door) connector.
2. Disconnect the G84 certification ECU (smart key ECU assembly) connector.
3. Measure the resistance according to the value(s) in the table below.

   Standard Resistance

   Tester Connection	Condition	Specified Condition
   I7-3 (ANT2) - G84 -10 (CG2B)	Always	Below 1 Ω
   I7-6 (ANT1) - G84-11 (CLG2)	Always	Below 1 Ω
   I7-5 (B) - G84-21 (POS2)	Always	Below 1 Ω
   I7-2 (GND) - Body ground	Always	Below 1 Ω
   I7-3 (ANT2) or G84-10 (CG2B) - Body ground	Always	10 kΩ or higher
   I7-6 (ANT1) or G84-11 (CLG2) - Body ground	Always	10 kΩ or higher
   I7-5 (B) or G84-21 (POS2) - Body ground	Always	10 kΩ or higher

Result: 

NG 

REPAIR OR REPLACE HARNESS OR CONNECTOR 

Result: 

OK 

See step  4

2. Measure the voltage according to the value(s) in the table below.

   Standard Voltage

   Tester Connection	Switch Condition	Specified Condition
   I7-5 (B) - I7-2 (GND)	Engine switch off → on (IG)	9 to 14 V → Below 2 V

3. Using an oscilloscope, check the waveform.

   OK

   Tester Connection	Switch Condition	Tool Setting	Specified Condition
   I7-3 (ANT2) - I7-6 (ANT1)	Procedure:  Engine switch off Electrical key transmitter sub-assembly brought outside vehicle All doors closed Electrical key transmitter sub-assembly not inside vehicle Electrical key transmitter sub-assembly brought outside detection area* All doors locked through wireless operation	2 V/DIV., 500 ms/DIV.	Pulse generation (See waveform)

   • *: For details about the areas that are inside the entry function detection area, refer to Operation Check.

     Refer to OPERATION CHECK [12/2012 - 08/2016] or OPERATION CHECK [08/2016 - ] .

Result: 

NG 

REPLACE CERTIFICATION ECU (SMART KEY ECU ASSEMBLY). Refer to  REMOVAL [12/2012 - 10/2015]  or  REMOVAL [10/2015 - ]  . 

Result: 

OK 

See step  5

1. Temporarily replace the front door outside handle assembly (for front passenger door) with a new or known good one.

   Refer to DISASSEMBLY [12/2012 - ]

Result: 

NEXT 

See step  6

1. Check that the entry functions operate normally.

   Refer to OPERATION CHECK [12/2012 - 08/2016] or OPERATION CHECK [08/2016 - ] .

   OK

   Entry functions operate normally.
