INSPECTION PROCEDURE

PROCEDURE

1. CHECK POWER DOOR LOCK OPERATION

   
   

   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 Click here.

      OK
      Door locks operate normally.

   
   

   NG

   GO TO POWER DOOR LOCK CONTROL SYSTEM Click here

   OK

2. CHECK WAVE ENVIRONMENT

   
   

   1. Bring the electrical key transmitter approximately 0.3 m (0.984 ft.) from the door outside handle (for front passenger side) and perform a front passenger side door entry lock and unlock operation check Click here.

      Note

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

      Tech Tips

      
      

      • When the electrical key transmitter is brought near the front passenger side door outside handle, 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 function operates normally.

3. READ VALUE USING INTELLIGENT TESTER (DOOR LOCK POSITION SWITCH)

   
   

   1. Connect the intelligent tester to the DLC3.

   2. Turn the engine switch on (IG).

   3. Turn the intelligent tester on.

   4. Enter the following menus: Body / Main Body / Data List.

   5. Read the Data List according to the display on the intelligent tester.

      Main Body

      Tester Display	Measurement Item/Range	Normal Condition	Diagnostic Note
      FR Door Lock Pos*1	Front RH side door lock position switch signal / UNLOCK or LOCK	UNLOCK: Front RH side door unlocked LOCK: Front RH side door locked	-
      FL Door Lock Pos*2	Front LH side door lock position switch signal / UNLOCK or LOCK	UNLOCK: Front LH side door unlocked LOCK: Front LH side door locked	-

      
      

      • *1: for LHD

      • *2: for RHD

      OK
      On the intelligent tester screen, the display changes between LOCK and UNLOCK as shown in the chart above.

   GO TO POWER DOOR LOCK CONTROL SYSTEM (Proceed to Only Front Passenger Door Lock/Unlock Functions do not Operate) Click here

   OK

4. CHECK HARNESS AND CONNECTOR (FRONT DOOR OUTSIDE HANDLE - CERTIFICATION ECU)

   
   

   1. Disconnect the N1*1 or O1*2 handle connector.

      
      

      • *1: for LHD

      • *2: for RHD

   2. Disconnect the G38 ECU connector.

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

      Standard Resistance
      for LHD
      Tester Connection Condition Specified Condition N1-3 (ANT2) - G38-6 (CG2B) Always Below 1 Ω N1-6 (ANT1) - G38-5 (CLG2) Always Below 1 Ω N1-5 (B) - G38-33 (POS2) Always Below 1 Ω N1-2 (GND) - Body ground Always Below 1 Ω G38-6 (CG2B) - Body ground Always 10 kΩ or higher G38-5 (CLG2) - Body ground Always 10 kΩ or higher G38-33 (POS2) - Body ground Always 10 kΩ or higher
      for RHD
      Tester Connection Condition Specified Condition O1-3 (ANT2) - G38-6 (CG2B) Always Below 1 Ω O1-6 (ANT1) - G38-5 (CLG2) Always Below 1 Ω O1-5 (B) - G38-33 (POS2) Always Below 1 Ω O1-2 (GND) - Body ground Always Below 1 Ω G38-6 (CG2B) - Body ground Always 10 kΩ or higher G38-5 (CLG2) - Body ground Always 10 kΩ or higher G38-33 (POS2) - Body ground Always 10 kΩ or higher

   
   

   NG

   REPAIR OR REPLACE HARNESS OR CONNECTOR

   OK

5. CHECK CERTIFICATION ECU (OUTPUT SIGNAL)

   
   
   1.

      *B	for RHD
      *a	Front view of wire harness connector (to Front Door Outside Handle Assembly [for Front Passenger Side])

      Disconnect the N1*1 or O1*2 handle connector.

      
      

      • *1: for LHD

      • *2: for RHD

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

      Standard Voltage
      for LHD
      Tester Connection Switch Condition Specified Condition N1-3 (ANT2) - N1-6 (ANT1) Engine switch off, all doors closed, key not in cabin and transmitter lock switch not pressed → pressed No pulse generation → Pulse generation N1-5 (B) - Body ground Engine switch off → on (IG) 9 to 14 V → Below 2 V
      for RHD
      Tester Connection Switch Condition Specified Condition O1-3 (ANT2) - O1-6 (ANT1) Engine switch off, all doors closed, key not in cabin and transmitter lock switch not pressed → pressed No pulse generation → Pulse generation O1-5 (B) - Body ground Engine switch off → on (IG) 9 to 14 V → Below 2 V
