Front Passenger Side Door Entry Lock and Unlock Functions do not Operate [03/2017 - ]: Procedure

1. When the door control switch on the power window regulator master switch assembly is operated, check that the doors unlock and lock according to switch operation (Refer to OPERATION CHECK [03/2017 - ] ).

   OK

   Door locks operate normally.

Result: 

NG 

GO TO POWER DOOR LOCK CONTROL SYSTEM (PROCEED TO PROBLEM SYMPTOMS TABLE). Refer to  PROBLEM SYMPTOMS TABLE [06/2016 - ] 

Result: 

OK 

See step  2

1. Bring the electrical key transmitter sub-assembly near the front door outside handle assembly RH, and perform a front passenger door entry lock and unlock operation check.

   *1	Electrical Key Transmitter Sub-assembly
   *a	Approximately 0.3 m (0.98 ft.)

   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 the electrical key transmitter sub-assembly is brought near the front door outside handle assembly RH, 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.

AFFECTED BY WAVE INTERFERENCE 

Result: 

A 

See step  3

1. Disconnect the D41 certification ECU (smart key ECU assembly) connector.
2. Disconnect the F5 front door outside handle assembly RH connector.
3. Measure the resistance according to the value(s) in the table below.

   Standard Resistance

   Tester Connection	Condition	Specified Condition
   D41-11 (CLG2) - F5-6 (ANT1)	Always	Below 1 Ω
   D41-10 (CG2B) - F5-3 (ANT2)	Always	Below 1 Ω
   D41-21 (POS2) - F5-5 (B)	Always	Below 1 Ω
   F5-2 (GND) - Body ground	Always	Below 1 Ω
   D41-11 (CLG2) or F5-6 (ANT1) - Body ground	Always	10 kΩ or higher
   D41-10 (CG2B) or F5-3 (ANT2) - Body ground	Always	10 kΩ or higher
   D41-21 (POS2) or F5-5 (B) - Body ground	Always	10 kΩ or higher

Result: 

NG 

REPAIR OR REPLACE HARNESS OR CONNECTOR 

Result: 

OK 

See step  4

1. Reconnect the D41 certification ECU (smart key ECU assembly) connector.
2. Using an oscilloscope, check the waveform.

REPLACE CERTIFICATION ECU (SMART KEY ECU ASSEMBLY). Refer to  REMOVAL [03/2017 - ] 

Result: 

OK 

See step  5

1. Temporarily replace the front door outside handle assembly RH with a new or known good one (Refer to DISASSEMBLY [03/2017 - 12/2017] Refer to DISASSEMBLY [12/2017 - ] ).

Result: 

NEXT 

See step  6

1. Check that the entry functions operate normally (Refer to OPERATION CHECK [03/2017 - 12/2017] Refer to OPERATION CHECK [12/2017 - ] ).

   OK

   Entry functions operate normally.

Result: 

OK 

END (FRONT DOOR OUTSIDE HANDLE ASSEMBLY RH WAS DEFECTIVE) 

Result:
