      OK

      When key is brought close to door oscillator that is ON, indicator light on key illuminates.

    NG → See step   4 

    OK → See step   11 

  4. CHECK HARNESS AND CONNECTOR (CERTIFICATION ECU [ECU AGGREGATION BOX ASSEMBLY] - DOOR ELECTRICAL KEY OSCILLATOR RH) 
    1. Disconnect the E84 certification ECU (ECU aggregation box assembly) connector.
    2. Disconnect the G10 door electrical key oscillator RH connector.
    3. Measure the resistance according to the value(s) in the table below.

      Standard Resistance

      Tester Connection Condition Specified Condition
      E84-35 (CLG2) - G10-10 (CLG) Always Below 1 Ω
      E84-36 (CG2B) - G10-5 (CLGB)
      E84-35 (CLG2) - Body ground Always 10 kΩ or higher
      E84-36 (CG2B) - Body ground

    NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

    OK: Go to next step 

  5. CHECK HARNESS AND CONNECTOR (DOOR ELECTRICAL KEY OSCILLATOR RH - ELECTRICAL KEY ANTENNA) 
    1. Disconnect the G10 door electrical key oscillator RH connector.
    2. Disconnect the G9 electrical key antenna connector.
    3. Measure the resistance according to the value(s) in the table below.

      Standard Resistance

      Tester Connection Condition Specified Condition
      G10-2 (SGT) - G9-6 (SGT) Always Below 1 Ω
      G10-3 (ANT1) - G9-5 (ANT1)
      G10-8 (ANT2) - G9-2 (ANT2)
      G10-9 (TRG-) - G9-1 (TRG-)
      G10-2 (SGT) - Body ground Always 10 kΩ or higher
      G10-3 (ANT1) - Body ground
      G10-8 (ANT2) - Body ground
      G10-9 (TRG-) - Body ground

    NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

    OK: Go to next step 

  6. CHECK HARNESS AND CONNECTOR (DOOR ELECTRICAL KEY OSCILLATOR RH - AUXILIARY BATTERY AND BODY GROUND) 
    1. Disconnect the G10 door electrical key oscillator RH connector.

    NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

    OK: Go to next step 

  7. CHECK HARNESS AND CONNECTOR (ELECTRICAL KEY ANTENNA - CERTIFICATION ECU [ECU AGGREGATION BOX ASSEMBLY]) 
    1. Disconnect the G9 electrical key antenna connector.
    2. Disconnect the E84 certification ECU (ECU aggregation box assembly) connector.
    3. Measure the resistance according to the value(s) in the table below.

      Standard Resistance

      Tester Connection Condition Specified Condition
      G9-3 (TRG+) - E84-4 (TSW2) Always Below 1 Ω
      G9-3 (TRG+) - Body ground Always 10 kΩ or higher

    NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

    OK: Go to next step
