CAUTION / NOTICE / HINT

PROCEDURE

1. CHECK POWER DOOR LOCK OPERATION

   
   

   1. When the master switch assembly door control switch is operated, check that the locked doors unlock Click here.

      OK
      Door locks operate normally.

   
   

   NG

   GO TO POWER DOOR LOCK CONTROL SYSTEM Click here

   OK

2. READ VALUE USING INTELLIGENT TESTER

   
   

   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
      P-Door Lock Pos SW	Front passenger side door lock position switch signal / ON or OFF	ON: Front passenger side door unlocked OFF: Front passenger side door locked	-

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

   
   

   NG

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

   OK

3. 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.

      

      *1	for LHD:
      *2	for RHD:
      *3	Approximately 0.3 m

      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.

      *1	for LHD
      *2	for RHD
      *3	Front view of wire harness connector (to Front Door Outside Handle Assembly (for Passenger Side))
      *4	Front view of wire harness connector (to Certification ECU)

      Disconnect the D54 ECU connector.

   2. Disconnect the E7*1 or E17*2 handle connector.

      *1: for LHD

      *2: for RHD

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

      Standard Resistance
      for LHD
      Tester Connection Condition Specified Condition E7-3 (ANT2) - D54-6 (CG2B) Always Below 1 Ω E7-6 (ANT1) - D54-5 (CLG2) Always Below 1 Ω E7-2 (GND) - Body ground Always Below 1 Ω D54-6 (CG2B) - Body ground Always 10 kΩ or higher D54-5 (CLG2) - Body ground Always 10 kΩ or higher
      for RHD
      Tester Connection Condition Specified Condition E17-3 (ANT2) - D54-6 (CG2B) Always Below 1 Ω E17-6 (ANT1) - D54-5 (CLG2) Always Below 1 Ω E17-2 (GND) - Body ground Always Below 1 Ω D54-6 (CG2B) - Body ground Always 10 kΩ or higher D54-5 (CLG2) - Body ground Always 10 kΩ or higher

   
   

   NG

   REPAIR OR REPLACE HARNESS OR CONNECTOR

   OK

5. INSPECT CERTIFICATION ECU

   
   

   1. Reconnect the D54 ECU connector.

      *1	for LHD
      *2	for RHD
      *3	Front view of wire harness connector (Front Door Outside Handle Assembly (for Passenger Side))

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

      Standard Voltage
      for LHD
      Tester Connection Condition Specified Condition E7-3 (ANT2) - E7-6 (ANT1) Engine switch off, all doors closed, all doors locked with wireless door lock control and key not in cabin No pulse generation → Pulse generation
      for RHD
      Tester Connection Condition Specified Condition E17-3 (ANT2) - E17-6 (ANT1) Engine switch off, all doors closed, all doors locked with wireless door lock control and key not in cabin No pulse generation → Pulse generation

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

      Standard Voltage
      for LHD
      Tester Connection Switch Condition Specified Condition E7-5 (B) - Body ground Engine switch off → Engine switch on (IG) 9 to 12 V → Below 2 V
      for RHD
      Tester Connection Switch Condition Specified Condition E17-5 (B) - Body ground Engine switch off → Engine switch on (IG) 9 to 12 V → Below 2 V
