Front Passenger Side Door Entry Lock and Unlock Functions do not Operate: 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 switch operation. Refer to OPERATION CHECK .

   OK

   Door locks operate normally.

NG → See step   8 

OK: Go to next step 

1. Connect the Techstream to the DLC3.
2. Turn the power switch on (IG).
3. Turn the Techstream on.
4. Enter the following menus: Body Electrical / Main Body / Data List.
5. According to the display on the Techstream, read the Data List.
   MAIN BODY
   
   

   Techstream Display	Measurement Item/Range	Normal Condition	Diagnostic Note
   FR Door Lock Pos	Front door lock detection switch RH signal / LOCK or UNLOCK	UNLOCK: Front RH side door locked LOCK: Front RH side door unlocked	-

   OK

   On the Techstream screen, the display changes between LOCK and UNLOCK as shown in the table above.

NG → See step   10 

OK: Go to next step 

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.

   *a	Approximately 0.3 m (0.98 ft.)

   NOTE:

   If the electrical key transmitter sub-assembly is brought within 0.2 m (0.656 ft.) of the front door outside handle assembly RH, 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.

   OK

   Entry functions operate normally.

NG → See step   4 

OK → AFFECTED BY WAVE INTERFERENCE 

1. Disconnect the C19 certification ECU (smart key ECU assembly) connector.
2. Disconnect the R1 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
   C19-6 (CG2B) - R1-3 (ANT2)	Always	Below 1 Ω
   C19-5 (CLG2) - R1-6 (ANT1)	Always	Below 1 Ω
   C19-33 (POS2) - R1-5 (B)	Always	Below 1 Ω
   R1-2 (GND) - Body ground	Always	Below 1 Ω
   C19-6 (CG2B) or R1-3 (ANT2) - Body ground	Always	10 kΩ or higher
   C19-5 (CLG2) or R1-6 (ANT1) - Body ground	Always	10 kΩ or higher
   C19-33 (POS2) or R1-5 (B) - Body ground	Always	10 kΩ or higher

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

OK: Go to next step 

1. Connect the C19 certification ECU (smart key ECU assembly) connector.

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

   Standard Voltage

   Tester Connection	Switch Condition	Specified Condition
   R1-5 (B) - Body ground	Power switch off → on (IG)	9 to 14 V → Below 2 V

3. Using an oscilloscope, check the waveform.

   OK

   Tester Connection	Condition	Tool Setting	Specified Condition
   R1-3 (ANT2) - R1-6 (ANT1)	Procedure: Power 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.

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

OK: Go to next step 

1. Temporarily replace the front door outside handle assembly RH with a new or normally functioning one. 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 RH WAS DEFECTIVE)
