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

      Standard resistance

      Tester Connection (Symbols) Condition Specified Condition
      o1-1 (TRG-) - o1-3 (TRG+) Lock switch not pushed 10 kΩor higher
      Lock switch pushed Below 1 Ω
      n1-1 (TRG-) - n1-3 (TRG+) Lock switch not pushed 10 kΩor higher
      Lock switch pushed Below 1 Ω

    NG → REPLACE OUTSIDE HANDLE ASSEMBLY 

    OK: Go to next step 

  2. CHECK HARNESS AND CONNECTOR (CERTIFICATION ECU - ENTRY LOCK SWITCH) 
    1. Disconnect the P33 ECU connector.

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

      Standard resistance

      Tester Connection (Symbols) Condition Specified Condition
      P33-3 (TSW1) - o1-3 (TRG+) Always Below 1 Ω
      P33-4 (TSW2) - n1-3 (TRG+) Always Below 1 Ω
      P33-3 (TSW1) - Body ground Always 10 kΩor higher
      P33-4 (TSW2) - Body ground Always 10 kΩor higher

    NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

    OK: Go to next step 

  3. CHECK HARNESS AND CONNECTOR (ELECTRICAL KEY OSCILLATOR - ENTRY LOCK SWITCH) 
    1. Disconnect the door oscillator connector.

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

      Standard resistance

      Tester connection (Symbols) Condition Specified condition
      o2-9 (TRG-) - o1-1 (TRG-) Always Below 1 Ω
      n2-9 (TRG-) - n1-1 (TRG-) Always Below 1 Ω
      o2-9 (TRG-) - Body ground Always 10 kΩor higher
      n2-9 (TRG-) - Body ground Always 10 kΩor higher

    NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

    OK: Go to next step 

  4. CHECK AND REPLACE ELECTRICAL KEY OSCILLATOR 
    1. Replace the electrical key oscillator.
    2. Check that the entry LOCK/UNLOCK function operates normally.

      OK

      Entry LOCK/UNLOCK function operates normally.

    NG → PROCEED TO NEXT CIRCUIT INSPECTION SHOWN IN PROBLEM SYMPTOMS TABLE 

    OK → END (ELECTRICAL KEY OSCILLATOR IS DEFECTIVE)
