Room Oscillator does not Recognize Key [09/2013 - ]: Procedure

  1. CHECK ELECTRICAL KEY TRANSMITTER SUB-ASSEMBLY (OPERATION) 
    1. Temporarily replace the electrical key transmitter sub-assembly with a new or normally functioning one. Refer to REMOVAL [09/2013 - ] .
    2. Check that the wireless door lock functions operate normally.

      OK

      Wireless door lock functions operate normally.

    NG → See step   2 

    OK → END (ELECTRICAL KEY TRANSMITTER SUB-ASSEMBLY WAS DEFECTIVE) 

  2. PERFORM ACTIVE TEST USING TECHSTREAM (INDOOR ELECTRICAL KEY OSCILLATOR) 
    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 / Smart Key / Active Test.
    5. According to the display on the Techstream, perform the Active Test.
      SMART KEY

      Tester Display Test Part Control Range Diagnostic Note
      Fr-Seat Inside Transmitter Indoor electrical key oscillator (front) ON or OFF -
      Inside Trunk/Backdoor Transmitter Indoor electrical key oscillator (rear) ON or OFF -

      OK

      When key is brought close to indoor electrical key oscillator, oscillator is turned OFF and indicator on key illuminates.

    NG → See step   3 

    OK → See step   5 

  3. CHECK HARNESS AND CONNECTOR (INDOOR ELECTRICAL KEY OSCILLATOR - CERTIFICATION ECU [ECU AGGREGATION BOX ASSEMBLY]) 
    1. Disconnect the L25*1 and K25*2 indoor electrical key oscillator connectors.
      • *1: for Front
      • *2: for Rear
    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

      for Front 

      for Rear 

      Tester Connection Condition Specified Condition
      L25-1 (ANTE5) - E84-11 (CLG5) Always Below 1 Ω
      L25-3 (CLGB) - E84-12 (CG5B)
      L25-1 (ANTE5) - Body ground Always 10 kΩ or higher
      L25-3 (CLGB) - Body ground
      Tester Connection Condition Specified Condition
      K25-1 (ANTE7) - E84-15 (CLG7) Always Below 1 Ω
      K25-3 (CLGB) - E84-16 (CG7B)
      K25-1 (ANTE7) - Body ground Always 10 kΩ or higher
      K25-3 (CLGB) - Body ground

    NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

    OK: Go to next step 

  4. CHECK INDOOR ELECTRICAL KEY OSCILLATOR (OPERATION) 
    1. Carry the key into the vehicle.
    2. Temporarily replace the indoor electrical key oscillator with a new or normally functioning one.
    3. Depress the brake pedal and check that the power switch indicator illuminates in green.

      OK

      Power switch indicator illuminates in green.

    NG → See step   5 

    OK → END (INDOOR ELECTRICAL KEY OSCILLATOR WAS DEFECTIVE) 

  5. REPLACE CERTIFICATION ECU (ECU AGGREGATION BOX ASSEMBLY). Refer to  REMOVAL [09/2013 - ]
